DETAILED DESCRIPTION

In the following, the technical solutions in the embodiments of the disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the disclosure. It will be apparent that the described embodiments are only part of the embodiments of the disclosure but not all of the embodiments. Based on the embodiments in the disclosure, all the other embodiments obtained by those of ordinary skill in the art without paying any creative work shall fall within the protection scope of the disclosure.

In the related art, multiple features are recognized and extracted from the same picture one by one, resulting in a complex process. It is difficult to associate the multiple features with each other, and the accuracy of association is low. Therefore, the disclosure provides a particular method for obtaining multi-dimensional information by picture-based integration. With the development of human face retrieval, human body retrieval and vehicle retrieval, the method provided in the disclosure can recognize and extract human faces, human bodies and vehicles from the same picture simultaneously, and associate the human faces, human bodies and vehicles automatically according to their position relationships with each other, to obtain the associated multi-dimensional information.

An advantageous effect of the disclosure over the related art is that: a to-be-detected picture is acquired, the to-be-detected picture is detected and multiple pieces of feature information are extracted from the to-be-detected picture; and target feature information and associated feature information are selected from the multiple pieces of feature information, and the target feature information is associated to the associated feature information to generate multi-dimensional information. The multi-dimensional information includes multiple pieces of feature information associated with each other. Therefore, automatic extraction, and automatic association of multiple pieces of feature information in the picture are achieved.

Specifically, referring to FIG. 1 which illustrates a schematic flowchart of a first embodiment of a method for obtaining multi-dimensional information by picture-based integration according to the disclosure.

The method for obtaining multi-dimensional information by picture-based integration according to the disclosure may be applied to an apparatus for obtaining multi-dimensional information by picture-based integration. The apparatus for obtaining multi-dimensional information by picture-based integration may be a terminal device such as a smartphone, a tablet computer, a notebook computer, a computer, or a wearable device, etc., or may be a monitoring system in a traffic block port system. Throughout the following descriptions of the embodiments, the method for obtaining multi-dimensional information by picture-based integration is described from the perspective of the apparatus for obtaining multi-dimensional information by picture-based integration. Specifically, the method for obtaining multi-dimensional information by picture-based integration as illustrated in FIG. 1 includes the following operations.

In operation S11: a to-be-detected picture is acquired.

Specifically, the to-be-detected picture may include one or more to-be-detected pictures. The to-be-detected picture may be a picture containing any of: a human face, a human body, and a vehicle. Specifically, the to-be-detected picture may contain one or more human faces, one or more human bodies, and one or more vehicles, which is not specifically limited.

In operation S12: the to-be-detected picture is detected and multiple pieces of feature information are extracted from the to-be-detected picture.

Specifically, the operation of extracting the multiple pieces of feature information from the to-be-detected picture includes extracting at least two of the following from the to-be-detected picture: human face feature information, human body feature information, or vehicle feature information. For example, in an embodiment, the human face feature information and the human body feature information may be extracted from the to-be-detected picture. Alternatively, the human body feature information and the vehicle feature information may be extracted from the to-be-detected picture. Alternatively, the human face feature information and the vehicle feature information may be extracted from the to-be-detected picture. Alternatively, the human face feature information, the human body feature information, and the vehicle feature information may be extracted from the to-be-detected picture.

In operation S13: target feature information and associated feature information are selected from the multiple pieces of feature information, and the target feature information is associated to the associated feature information to generate multi-dimensional information. Herein the multi-dimensional information includes multiple pieces of feature information associated with each other.

Specifically, after obtaining the multiple pieces of feature information (the human face feature information, the human body feature information, and the vehicle feature information) from the to-be-detected picture by detection, one of the multiple pieces of feature information may be taken as the target feature information, and the remaining of the multiple pieces of feature information may be taken as the associated feature information. The target feature information is associated to the associated feature information according to the position relationship to form the multi-dimensional information. Specifically, the multi-dimensional information may include multiple pieces of feature information associated with each other.

In a particular embodiment, S13 may be performed through the method as illustrated in FIG. 2. Specifically, the method includes the following operations.

In operation S21: a control instruction is received, and the target feature information and the associated feature information are selected from the multiple pieces of feature information based on the control instruction. Herein, the selected target feature information and the selected associated feature information include at least two different types of information of the following: the human face feature information, the human body feature information, or the vehicle feature information.

In a particular embodiment, in order to further improve the accuracy of tracking, the target feature information may also include two different types of feature information in the embodiment. For example, the selected target feature information may include both human face feature information and human body feature information, or may include both human face feature information and vehicle feature information, or may include both human body feature information and vehicle feature information.

In operation S22: the target feature information is associated to the associated feature information to generate the multi-dimensional information.

The selected target feature information is integrated and associated to the associated feature information according to a position relationship to form the multi-dimensional information.

According to the method for obtaining multi-dimensional information by integration in the embodiment, multiple pieces of feature information can be recognized simultaneously. Moreover, by selecting target feature information and associated feature information from the multiple pieces of feature information, and further integrating the target feature information with the associated feature information to form the multi-dimensional information, associated features associated with different target features can be determined through the target features, so as to achieve automatic association. Furthermore, the accuracy of association is improved through association from different perspectives.

In an implementation, as illustrated in FIG. 3, the operation S13 includes the following sub-operations.

In sub-operation S31: target human face feature information corresponding to a target human face with a highest quality score in the to-be-detected picture is selected as the target feature information, and at least one of the following is selected as the associated feature information: target human body feature information corresponding to the target human face feature information, or target vehicle feature information corresponding to a vehicle closest to a center point of the target human face.

After performing feature extraction on the to-be-detected picture, the human face feature information, the human body feature information and the vehicle feature information are extracted from the to-be-detected picture. The extracted target human face feature information with the highest quality score is used as the target feature information, and human body feature information containing the human face feature information of the target human face and target vehicle feature information corresponding to a vehicle closest to the center point of the target human face are used as the associated feature information. Then the selected human face feature information, the human body feature information, and the vehicle feature information are associated to each other.

In sub-operation S32: the target feature information is associated to the associated feature information to generate multi-dimensional information. Herein, the multi-dimensional information includes at least two different types of features information of the following: the target human face feature information, the target human body feature information, or the target vehicle feature information.

Specifically, when the target feature information is associated to the associated feature information to form the multi-dimensional information, if the target feature information includes one type of feature information and the associated feature information also includes one type of feature information, the multi-dimensional information includes two different types of feature information. For example, if the target feature information includes human face feature information and the associated feature information includes human body feature information, the multi-dimensional information includes two different types of feature information: the human face feature information and the human body feature information. For another example, if the target feature information includes one type of feature information and the associated feature information includes two different types of feature information, the multi-dimensional information includes three different types of feature information. For example, if the target feature information includes human face feature information and the associated feature information includes human body feature information and vehicle feature information, the multi-dimensional information includes three different types of feature information: the human face feature information, the human body feature information, and the vehicle feature information.

According to the method for obtaining multi-dimensional information by integration of the embodiment, the target human face feature information corresponding to the target human face with the highest quality score is selected as the target feature information, and at least one of target human body feature information corresponding to the target human face feature information, or target vehicle feature information corresponding to the vehicle closest to the center point of the target human face is selected as the associated feature information. Herein the human face with the highest quality score is the clearest human face in the to-be-detected picture. Therefore, the accuracy of association can be improved, so as to prevent the case where a human face and a human body without correspondence are associated to each other, or a human face and a vehicle without correspondence are associated to each other.

In another implementation, as illustrated in FIG. 4, the operation S13 includes the following sub-operations.

In sub-operation S41: a control instruction is received, and the target feature information is selected from the multiple pieces of feature information based on the control instruction. Herein the target feature information is one of: the human face feature information, the human body feature information, or the vehicle feature information.

Specifically, a piece of feature information may be selected from the feature information obtained by detection as the target feature information, and the remaining feature information may be taken as the associated feature information.

Herein the target feature information may be human face feature information, or may be human body feature information, or may be vehicle feature information, which is not specifically limited.

In sub-operation S42: associated feature information matching with the target feature information is selected according to the selected target feature information. Herein the associated feature information matching with the target feature information includes at least one type of information of the following other than a type of the target feature information: the human face feature information, the human body feature information, or the vehicle feature information.

In a particular embodiment, if the selected target feature information is human face feature information, human body feature information and vehicle feature information matching therewith are selected from the remaining feature information according to the selected human face feature information. If the selected target feature information is human body feature information, human face feature information and vehicle feature information matching therewith are selected from the remaining feature information according to the selected human body feature information. If the selected target feature information is vehicle feature information, human face feature information and human body feature information matching therewith are selected from the remaining feature information according to the selected vehicle feature information.

In sub-operation S43: the target feature information is associated to the associated feature information matching with the target feature information to generate the multi-dimensional information.

The selected target feature information is associated to the associated feature information matching with the target feature information to generate the multi-dimensional information. Specifically, the human face feature information, the human body feature information, and the vehicle feature information are associated to each other to generate the multi-dimensional information including the human face feature information, the human body feature information, and the vehicle feature information.

Specifically, in an embodiment, when the feature information is detected, the coordinate position corresponding to each piece of feature information is acquired at the same time. The target feature information is integrated and associated to the associated feature information according to the coordinate position corresponding to the target feature information and the coordinate position corresponding to the associated feature information. For example, when the human face feature information is detected in the to-be-detected picture, coordinates around the human face feature are acquired to form a bounding box surrounding the human face feature. When the human body feature information is detected in the to-be-detected picture, coordinates around the human body feature are acquired to form a bounding box surrounding the human body feature. When the vehicle feature information is detected in the to-be-detected, coordinates around the vehicle feature are acquired to form a bounding box surrounding the vehicle feature.

In a particular embodiment, in the case where the human face feature information is selected as the target feature information, when the associated feature information matching therewith is selected according to the target feature information (the human face feature information), a bounding box of human body feature information which contains the bounding box of the selected human face feature information is determined. In this case, the human body feature information within the bounding box of human body feature information matches with the human face feature information. A bounding box of vehicle feature information which contains a vehicle closest to the center point of the bounding box of the selected human face feature information is determined. In this case, the vehicle feature information within the bounding box of vehicle feature information matches with the human face feature information. The human face feature information, the human body feature information and the vehicle feature information are associated and integrated to each other according to the coordinate positions of the bounding boxes.

In another particular embodiment, in the case where the human body feature information is selected as the target feature information, when the associated feature information matching therewith is selected according to the target feature information (the human body feature information), it is determined whether the bounding box of the selected human body feature information contains a bounding box of selected human face feature information; if yes, the human face feature information in the bounding box of selected human face feature information matches with the human body feature information. A bounding box of vehicle feature information which contains the vehicle closest to the center point of the bounding box corresponding to the selected human body feature information is determined. In this case, the vehicle feature information within the bounding box of vehicle feature information matches with the human body feature information. The human face feature information, the human body feature information and the vehicle feature information are associated and integrated with each other according to the coordinate positions of the bounding boxes.

In yet another embodiment, in the case where the vehicle feature information is selected as the target feature information, when the associated feature information matching therewith is selected according to the target feature information (the vehicle feature information), a bounding box containing human face feature information and a bounding box containing human face feature information which are closest to the center point of the bounding box of the selected vehicle feature information are determined. Herein the human face feature information within the bounding box containing the human face feature information matches with the vehicle feature information, and the human body feature information within the bounding box containing the human body feature information matches with the vehicle feature information. The human face feature information, the human body feature information and the vehicle feature information are associated and integrated to each other according to the coordinate positions of the bounding boxes.

According to the method for obtaining multi-dimensional information by picture-based integration as described in the embodiment, the associated feature information matching with the target feature information is determined by the positions of the target feature information and the associated feature information, and the target feature information and the associated feature information are integrated and associated to each other. Thus, automatic extraction, and automatic association and integration of multiple pieces of feature information are realized. The labor burden of staffs can be greatly reduced and thus the work efficiency is improved in practical applications.

FIG. 5 illustrates a schematic flowchart of a second embodiment of the method for obtaining multi-dimensional information by picture-based integration according to the disclosure.

The embodiment includes operations S51˜S53 which are the same as operations S11˜S13 in FIG. 1, and differs from the first embodiment in that the method further includes the following operations after operation S13.

In operation S54: a first target image is retrieved from a first database based on the target feature information in the multi-dimensional information.

Specifically, after the multi-dimensional information is obtained by synthesis, the multi-dimensional information is input to the first database for retrieval, to acquire the first target image corresponding to the target feature information in the multi-dimensional information. Specifically, in an embodiment, if the target feature information in the multi-dimensional information is human face feature information, the first database is a human face feature database. The human face feature information in the multi-dimensional information is matched with the human face feature database to acquire multiple first target images matching with the human face feature information.

In operation S55: a second target image is retrieved from a second database based on the associated feature information in the multi-dimensional information.

Specifically, in an embodiment, if the associated feature information in the multi-dimensional information is human body feature information, the second database is a human body feature database. The human body feature information in the multi-dimensional information is matched with the human body feature database to acquire multiple second target images matching with the human body feature information. Alternatively, in an embodiment, if the associated feature information in the multi-dimensional information is vehicle feature information, the second database is a vehicle feature database. The vehicle feature information in the multi-dimensional information is matched with the vehicle feature database to acquire multiple second target images matching with the vehicle feature information.

In operation S56: the first target image and the second target image are determined as a retrieval result of the to-be-detected picture.

Specifically, the retrieved first target image and second target image are the retrieval result corresponding to the to-be-detected picture. In an embodiment, if the first target image and the second target image are integrated with each other, the motion trajectory corresponding to at least one of the target feature information or the associated feature information can be acquired according to the photographing locations and the photographing time of the first target image and the second target image. Specifically, this solution may be applied to criminal investigation for search of escape routes of suspects or target persons. When searching for suspects and tracking target persons, the method for obtaining multi-dimensional information by integration in the embodiment can greatly reduce the labor burden of staffs, thereby improving the work efficiency.

Specifically, after the first target image and the second target image are determined as the retrieval result pictures of the to-be-detected picture, other pictures corresponding to the retrieval result pictures may also be searched according to the retrieval result pictures.

Specifically, please refer to FIG. 6 which illustrates a schematic flowchart of a third embodiment of the method for obtaining multi-dimensional information by picture-based integration according to the disclosure. The third embodiment includes operations S61˜S66 which are the same as operations S51˜S56 in FIG. 5, and differs from the second embodiment in that the method further includes the following operations after operation S56.

In operation S67: at least one of the following is acquired: a target human face picture corresponding to the human face feature information, a target human body picture corresponding to the human body feature information, or a target vehicle picture corresponding to the vehicle feature information.

Specifically, the target human face picture containing the human face feature may be acquired according to the human face feature. Herein the target human face picture may contain the human face feature, the human body feature, and the vehicle feature. The target human body picture containing the human body feature may also be acquired according to the human body feature. Herein the target human body picture may contain the human face feature, the human body feature, and the vehicle feature. The target vehicle picture containing the vehicle feature may also be acquired according to the vehicle feature. Herein, the target vehicle picture may contain the human face feature, the human body feature, and the vehicle feature.

In operation S68: at least one of the following is performed. In response to that the target human face picture corresponds to a same first target image as the target human body picture and has a preset spatial relationship with the target human body picture, the target human face picture and the target human body picture in the retrieval result pictures are associated to each other. In response to that the target human face picture corresponds to a same first target image as the target vehicle picture, and has a preset spatial relationship with the target vehicle picture, the target human face picture and the target vehicle picture in the retrieval result pictures are associated to each other. In response to that the target human body picture corresponds to a same first target image as the target vehicle picture and has a preset spatial relationship with the target vehicle picture, the target human body picture and the target vehicle picture in the retrieval result pictures are associated to each other.

Specifically, the first target image (which may contain a human face and a human body) is acquired. The first target image may include the target human face picture and the target human body picture, one of which is a first target picture, and the the other of which is a second target picture. If the coverage of the first target picture contains the coverage of the second target picture, or the image coverage of the first target picture partially overlaps the image coverage of the second target picture, or the image coverage of the first target picture is connected with the image coverage of the second target picture, the target human face picture and the target human body picture in the retrieval result pictures are associated to each other.

In this case, if a first target image includes only a human face picture and a second target image includes only a human body picture, the human face picture may serve as a target human face picture, and the human body picture may serve as a target human body picture; and the target human face picture may be associated to the target human body picture to obtain a complete associated image. In this way, the human body may be searched through the human face, or the human face may be searched through the human body.

Alternatively, the first target image (which may contain the human face and the vehicle) is acquired. The first target image may include the target human face picture and the target vehicle picture, one of which is a first target picture, and the the other of which is a second target picture. If the coverage of the first target picture contains the coverage of the second target picture, or the image coverage of the first target picture partially overlaps the image coverage of the second target picture, or the image coverage of the first target picture is connected with the image coverage of the second target picture, the target human face picture and the target vehicle picture in the retrieval result pictures are associated to each other.

In this case, if a first target image contains only a human face picture and a second target image contains only a vehicle picture, the human face picture may serve as a target human face picture and the vehicle picture may serve as a target vehicle picture; and the target human face picture may be associated to the target vehicle picture to obtain a complete associated image. In this way, the vehicle may be searched through the human face, or the human face may be searched through the vehicle.

Alternatively, the first target image (which may contain the human body and the vehicle) is acquired. The first target image may include the target human body picture and the target vehicle picture, one of which is a first target picture, and the the other of which is a second target picture. If the coverage of the first target picture contains the coverage of the second target picture, or the image coverage of the first target picture partially overlaps the image coverage of the second target picture, or the image coverage of the first target picture is connected with the image coverage of the second target picture, the target human body picture and the target vehicle picture in the retrieval result pictures are associated to each other.

In this case, if a first target image contains only a human body picture and a second target image contains only a vehicle picture, the human body picture may serve as a target human body picture and the vehicle picture may serve as a target vehicle picture; and the target human body picture may be associated to the target vehicle picture to obtain a complete associated image. In this way, the vehicle may be searched through the human body, or the human body may be searched through the vehicle.

According to the method described in the embodiment, through the preset spatial relationship among the human face, the human body and the vehicle, the human body may be searched through the vehicle and the vehicle may be searched through the human body, or the human body may be searched through the human face and the human face may be searched through the human body, or the human face may be searched through the vehicle and the vehicle may be found through the human face. In practical applications, with only one of the human face, the human body and the vehicle of the tracking target, the multi-dimensional information of the tracking target can still be obtained. In this case, the feasibility of this solution is further improved and the work efficiency is improved on the premise of achieving automatic association.
