The present invention relates to a construction technical field and, in particular, to a construction inspection method, apparatus, and system.
With the development of urbanization and the improvement of modernization, various constructions have become huge in size and complicated, but the traceability of construction quality management with the low level of computerization has always become a shortboard of the industry. Further, for the inspection of constructions, manual inspection is usually performed, but its efficiency is low, and execution of unified standards is also not possible. In addition, when a typical operation is performed on the concealed construction during the construction, it is almost impossible to accurately determine the construction quality, and the inspection operation is inconvenient, and therefore, the construction period of the construction becomes long, and the construction quality cannot be secured.
In recent years, a technique of using a virtual building construction three-dimensional model for supporting construction quality management has appeared.

In the attached drawings,
Preferred embodiments of the present invention will be described below with reference to the drawings.
A first embodiment of the present invention provides a construction inspection method.
Thus, the established model is compared with the design model based on the result actually detected at the site, and therefore the difference between the actually completed situation of the construction and the desired design plan may be accurately reflected, the accuracy of the inspection result may be high, and the inspection may also be performed according to a unified standard. In addition, as the two models are directly compared with each other, the processing process is simple, and the inspection efficiency is high. After the inspection result is obtained, the inspection result may also be shared with the user. Thus, the user at a location other than the site may also acquire the inspection result in a timely manner, which improves the inspection efficiency, enhances the convenience of inspection, saves time and effort, and improves the user experience.
According to an embodiment of the present invention, the construction site may also be, for example, an operation site of a construction such as inside a building or may also be an outdoor site.
According to an embodiment of the present invention, the construction inspection method may be used for inspection of various constructions, such as installation of air conditioners, constructions of buildings, or interior constructions.
According to an embodiment of the present invention, the construction inspection method may be applied to each stage during the construction, for example, intermediate inspection or completion inspection.
At Step 101, the first construction model is established based on detection data at the construction site.
According to an embodiment of the present invention, the first construction model may be used to simulate a currently completed construction site and all components that are included in the construction and are present at the construction site, and the information of each component may be stored or marked in the first construction model.
For example, when the construction is installation of an air conditioner, the construction may include at least one of components such as an indoor unit, an outdoor unit, a refrigerant pipeline, an electric wire pipeline, a condensation pipeline, and a control panel.
According to an embodiment of the present invention, the information of the component may be various types of information related to the component. For example, the information of the component may include at least one of the position, angle, model number, size, name, identifier, color, category, serial number, brand, material, and surface precision of the component.
According to an embodiment of the present invention, the detection data may be various types of detection data with which the first construction model may be established. Examples thereof may include laser radar signals, image signals, or ground penetrating radar signals.
For example, as illustrated in
According to an embodiment of the present invention, Step 105 is a selectable step in the construction inspection method. For example, the detection data at the construction site may be acquired before the construction inspection method is performed.
For example, the construction site is scanned by a laser radar sensor to acquire a returned laser radar signal, and the first construction model is established based on the returned laser radar signal.
According to an embodiment of the present invention, the laser radar sensor may be provided in an augmented reality (Augmented Reality, AR) device, may be provided in a virtual reality (Virtual Reality, VR) device, or may be provided in a mixed reality (Mixed Reality, MR) device.
Thus, the AR device, the VR device, or the MR device may acquire the detection signal to establish the first construction model and thus intuitively observes the first construction model and may facilitate subsequent model comparison and inspection.
According to an embodiment of the present invention, the AR device may be various types of AR devices. Examples thereof may include AR glasses, smart phones, tablets, or customized AR hand-held devices.
For example, a laser radar sensor attached to the AR glasses transmits a laser radar signal to scan the entire construction site and acquires the laser radar signal returned to the sensor.
For a specific modeling process, reference may be made to a related background art.
According to an embodiment of the present invention, for example, the construction site may be captured by an imaging device to acquire an image signal, and the first construction model may be established based on the image signal.
According to an embodiment of the present invention, the imaging device may be provided in an unmanned device or a robot. The construction site may be captured by the unmanned device or robot and thus captured at multiple angles and in all directions. Accordingly, the accuracy of the established first construction model is ensured.
For example, the image signal is acquired by performing inclination capturing measurement by the unmanned device. For example, in the inclination capturing measurement, a ground object may be captured by five cameras mounted on the unmanned device from five directions, front, rear, left, right, and vertical directions, and then a series of processing such as geometric correction, balance adjustment, and multi-view video verification may be performed to acquire image data having omnidirectional information of the ground object, and then the first construction model may be modeled based on the image data. For a specific modeling process, reference may be made to a related background art.
According to an embodiment of the present invention, for example, a ground penetrating radar (Ground Penetrating Radar, GPR) device may further transmit a high-frequency electromagnetic wave to the construction site to acquire a returned electromagnetic wave signal and establish the first construction model based on the returned electromagnetic wave signal. By establishing the first construction model with the ground penetrating radar signal, internal structures, which cannot be observed from outside, may be modeled. Examples thereof may include dark pipelines in a wall or underground, and various devices or structures closed by a ceiling.
For example, high-frequency electromagnetic waves are transmitted to the construction site by a transmitting antenna, and reflected electromagnetic waves are received by a receiving antenna, electromagnetic waves are reflected when they encounter a boundary surface having an electrical difference during propagation, and the spatial position, structure, form, embedding depth, and the like, of an internal component are inferred in accordance with the characteristics of the waveform, amplitude intensity, and temporal change of the received electromagnetic waves to acquire the information of the component, and the first construction model is established based on the information of the component at the construction site. For a specific modeling process, reference may be made to a background art.
According to an embodiment of the present invention, it is possible to determine which one of the laser radar signal, the image signal, and the ground penetrating radar signal is used to establish the first construction model according to an application situation.
For example, when the construction may be observed from outside, the laser radar signal or the image signal may be used to establish the first construction model; however, when it is difficult to observe the construction from outside or it is difficult to observe some components in the construction from outside, the ground penetrating radar signal may be used to establish the first construction model.
For example, for the installation of a central air conditioner, when the installation of the air conditioner is finished and there is no ceiling, the first construction model may be established by using the laser radar signal or the image signal, but when the installation of the air conditioner is finished and there is a ceiling, the first construction model may be established by using the ground penetrating radar signal.
According to an embodiment of the present invention, as described above, the information of the component in the first construction model may include at least one of the position, angle, model number, size, name, identifier, color, category, serial number, brand, material, and surface precision of the component. When it is difficult to directly acquire some of the information from the detection signal, it may be acquired in combination with other techniques.
For example, the image signal is input into a previously established AI model to be identified and determine the material of the component.
In addition, according to an embodiment of the present invention, various detection signals may be combined to establish the first construction model. For example, the laser radar signal and the ground penetrating radar signal may be combined to establish the first construction model.
According to an embodiment of the present invention, after the first construction model is established, in Step 102, the first construction model is compared with the previously established second construction model based on construction design data to acquire a comparison result.
According to an embodiment of the present invention, the second construction model is previously established based on the design data of the construction and may be various three-dimensional models. For example, the second construction model may be a building information model (Building Information Modeling, BIM).
According to an embodiment of the present invention, the second construction model may include information of all the components in the construction, and the information of the components may be various types of information related to the components. For example, the information of the component may include at least one of the position, angle, model number, size, name, identifier, color, category, serial number, brand, material, and surface precision of the component.
According to an embodiment of the present invention, the data of the second construction model may be previously stored in a terminal device used at the inspection site, such as an AR device.
Alternatively, the data of the second construction model may be acquired by the terminal device from a server of a cloud terminal.
According to an embodiment of the present invention, for example, as illustrated in
Accordingly, the second construction model matched with the position of the construction site, the established first construction model, and the comparison result are displayed on the site by the AR device, which is an augmented reality device, and thus the accuracy of inspection is improved, and the difference between the two models, i.e., the comparison result, may be intuitively observed.
According to an embodiment of the present invention, Step 106 is a selectable step.
According to an embodiment of the present invention, the second construction model may not be positioned at the construction site. In this way, the efficiency of the operation at the site is increased, and the flexibility is high.
According to an embodiment of the present invention, the positioning of the second construction model may be implemented in various ways.
For example, positioning may be performed with two location points at the construction area. The positioning operation with two points is simple and suitable for a wide range of personnel. By simply establishing two points on the ground, the second construction model and the construction area, e.g., a building body, may be positioned together.
Further, for example, positioning may be performed with a wall at the construction area. The positioning with the wall is positioning with three points, which may further increase the superimposition accuracy of the second construction model and the construction area and further improves the inspection accuracy.
Further, for example, the positioning may be performed by scanning a two-dimensional code installed at the construction area. For example, the two-dimensional code includes information of one wall at the construction area. Thus, the superimposition accuracy between the second construction model and the construction area may be further increased, and the accuracy of inspection is further improved. At the same time, the time required for point calibration is saved, and the accuracy of inspection is further improved.
Further, for example, positioning may be performed by a geographic information system (Geographic Information System, GIS).
According to an embodiment of the present invention, the construction inspection method may further include a step of matching a coordinate point of the first construction model to coincide with a coordinate point of the second construction model. Accordingly, the accuracy of the comparison result between the first construction model and the second construction model is increased, and the accuracy of inspection is further improved.
For example, when the first construction model is established, the coordinate point of the first construction model may be matched to coincide with the coordinate point of the second construction model. Accordingly, after the first construction model is established, it may be directly compared with the second construction model so that the processing process is simple and the inspection efficiency may be further improved.
Further, for example, when the first construction model is compared with the second construction model, matching may be performed such that the coordinate point of the first construction model coincides with the coordinate point of the second construction model. Accordingly, it is not necessary to perform alignment with respect to the model at the site, and thus labor saving may be achieved.
At Step 102, collisional verification between the first construction model and the second construction model may be performed to acquire the comparison result.
In Step 102, the information of all the components in the first construction model may be compared with the information of the corresponding components in the second construction model one by one to specify the component having a mismatch. For example, the ID of the component having a mismatch may be recorded. In addition, specific content of the mismatch may be recorded.
For example, the information of the component may include at least one of the position, angle, model number, size, name, identifier, color, category, serial number, brand, material, and surface precision of the component.
According to an embodiment of the present invention, the construction inspection method may further include a step of marking the component having the mismatch in the second construction model, and a step of displaying, by an augmented reality device, the second construction model in which the component having the mismatch is marked. Accordingly, it is possible to intuitively observe the component having a mismatch.
After acquiring the comparison result, in Step 103, the inspection result of the construction is confirmed in accordance with the comparison result.
For example, when the position mismatch is greater than the position mismatch defined in the inspection standard, it is confirmed that the construction is defective, and when the position mismatch is less than or equal to the position mismatch defined in the inspection standard, it is confirmed that the construction is successful.
For various constructions, inspection standards in different industries or self-defined inspection standards by manufacturers may be used.
For example, for the installation of air conditioners, the inspection standard may include a pipeline and wiring inspection standard of air conditioners, and the inspection items are air conditioners, liquid pipes, gas pipes, supporting and lifting brackets, buckles, pipe joints, ducts, valves, and the like.
For example, the quality inspection items of the air conditioner may include a device model number, spatial position, horizontal angle, and vertical angle. Here, it is assumed that the position mismatch of the air conditioner is ±20 cm or less and the angle mismatch is ±10° or less. The liquid pipe and the gas pipe are requested to be provided with a thermal insulation material, the position mismatch of the liquid pipe and the gas pipe is ±30 cm or less, and the inclination angle is requested to meet the design requirement and not to exceed 10% beyond the range. The interval of the supporting and lifting bracket is requested to meet the design requirements and not to exceed 20% beyond the designed interval, and the inclination angle is requested not to exceed 10%. A shock absorbing pad is requested to be attached to a hanging leg. Buckles are requested to be rigid, and the number is requested to meet the design requirements. The quality inspection of the ducts is performed in accordance with the categories of the material, the machining process, and the system, and the quality inspection is requested to meet the design requirements, including the material, specification (radius and length), strength, and strictness of the ducts. The mounting position, height, and inlet and outlet directions of valves need to meet the design requirements, and the connection need to be secure and tight.
According to an embodiment of the present invention, the construction inspection method may further include a step of displaying an inspection result by a virtual reality (VR) device. For example, by transmitting the inspection result to the VR device and displaying the inspection result on the construction site or remotely by the VR device, the worker or the user may intuitively confirm the inspection result.
After the inspection result is acquired, in Step 104, the inspection result may be shared with the user. According to an embodiment of the present invention, the user is a user who is not at the construction site at the time of inspection.
For example, the inspection result may be transmitted to a server of the cloud terminal and shared with a specific user.
According to an embodiment of the present invention, the specific user is, for example, a client or another inspector who is not at the construction site.
In addition, according to an embodiment of the present invention, the second construction model may also be updated according to the inspection result.
According to an embodiment of the present invention, the construction inspection method may be implemented by local processing. That is, it is executed by a terminal device at the inspection site. For example, it may be executed by an AR device.
Alternatively, the construction inspection method may be implemented by processing using a cloud terminal. That is, it may be executed by a server of a cloud terminal.
For example, the terminal device at the inspection site may transmit the detection data to the server of the cloud terminal, and the server of the cloud terminal may execute each step of the construction inspection method.
The process in the cloud terminal and the process in the local terminal according to the construction inspection method will be described below in detail by taking the installation of the air conditioner as an example.
Accordingly, the server of the cloud terminal mainly performs the process of inspection, which increases the processing speed and lowers the requirement on the processing capability of the hardware of the AR device.
Accordingly, the process of inspection by the local terminal device is mainly performed, which may be applied to various network states.
As may be understood from the above embodiment, the first construction model is established at the construction site based on the detection data at the site, the first construction model is compared with the previously established second construction model based on the design data, and the inspection result is confirmed in accordance with the comparison result so that the model established based on the result actually detected at the site is compared with the design model, and therefore it is possible to accurately reflect the difference between the actually completed situation of the construction and the desired design plan, the inspection result may be highly accurate, and the inspection may also be performed according to a unified standard. In addition, as the two models are directly compared with each other, the processing process is simple, and the inspection efficiency is high. After the inspection result is acquired, the inspection result may be shared with the user. Thus, the user at a location other than the site may also acquire the inspection result in a timely manner, which improves the inspection efficiency, enhances the convenience of inspection, saves time and effort, and improves the user experience.
