DETAILED DESCRIPTION

In order to solve the conventional problem that the GPS or the wireless communication system can not be utilized indoors for guiding the vehicle to a vacant parking space, the present invention provides a method and a device for guiding a parking space indoors, such that the driver can find the vacant parking space quickly, so as to reduce the time for finding a parking space. Please refer to FIG. 1, which is a schematic diagram of a parking space guiding process 10 according to an embodiment of the present invention. The parking space guiding process 10 is utilized for an electronic device. The electronic device can be a PDA, a tablet personal computer, a mobile telephone, a car navigation system or a vehicle computer, etc., which is not limited herein. The parking space guiding process 10 includes the following steps:

Step 100: Start.

Step 110: Obtain location information of a parking space.

Step 120: Calculate a destination position according to the location information.

Step 130: Determine a movement of the vehicle via at least one sensor of the electronic device to generate a determination result.

Step 140: Generate a guiding indication for guiding the vehicle to the destination position according to the determination result and the destination position.

Step 150: End.

According to the parking space guiding process 10, the electronic device on the vehicle obtains the location information of the parking space first, and calculates the destination position of the parking space according to the location information. The electronic device then determines a direction and distance of the movement of the vehicle via at least one sensor, in order to generate the guiding indication corresponding to the destination position according to the direction and distance of the movement of the vehicle, in order to guide the vehicle to the parking space. Please note that the location information may include data related to path, distance, parking space number and/or coordination, etc.

For example, please refer to FIG. 2, which is a schematic diagram of a ticket issuing machine according to an embodiment of the present invention. The ticket issuing machine is set up at the entrance of the parking lot, and has a server for storing parking space information. The parking space information includes a parking space guide, and the parking space guide can be coded as a mobile barcode such as a Quick Response Code (QR Code). Please note that the mobile barcode can be displayed on the screen of the ticket issuing machine or printed on a parking ticket. After obtaining the mobile barcode, the driver can utilize related software (e.g. a QR code reader) on a mobile device (e.g. a smart phone) to scan the mobile barcode and to decode to obtain the parking space guide. After obtaining the parking space guide, the smart phone can obtain a turning angle of the vehicle via a sensor (e.g. a gyro meter), and calculate a distance of the movement of the vehicle via an acceleration sensor. Please note that, the types of sensors are not limited herein, and as long as a sensor can be utilized for detecting the movement of the vehicle, the sensor can be realized in the embodiments of the present invention. Besides, operations of the gyro meter and the acceleration sensor are well known by those skilled in the art, and the functions and characteristics of these sensors will not be narrated herein.

In addition, please refer to FIG. 3, which is a schematic diagram of an image of modeling the parking space guiding according to an embodiment of the present invention. According to the embodiment of the present invention, after the sensor obtains the movement of the vehicle, the smart phone may generate related direction indication according to the parking space guide and the movement of the vehicle, and the direction indication is displayed on the screen of the smart phone in an augmented reality (AR) manner together with the image captured by the camera of the smart phone, such that the driver can arrive the destination position of the parking space accurately.

In short, the driver downloads the QR code assigned by the ticket issuing machine of the parking lot via the camera of the smart phone, and the location information is converted from the diagram of the QR code. The smart phone then sets the destination position according to the location information, performs guiding via the sensors, and utilizes an arrow on the screen to indicate the moving direction, in order to lead the driver to the destination. Therefore, according to the embodiment of the present invention, the purpose of guiding the vehicle to the vacant parking space can be achieved by using the application installed in the wireless communication device (e.g. the smart phone) together with the photographic function and the sensors of the smart phone. Please note that the embodiment of the present invention can be utilized indoors, which solves the problem that the conventional GPS or the wireless communication system are limited to bad reception and cannot perform the positioning and guiding functions indoors.

Those skilled in the art can realize the parking space guiding process 10 in a software or hardware manner. For example, the electronic device may include a storage unit, which can be any one of data store devices such as read-only memory (ROM), for storing data. The stored data includes a program compiled according to the parking space guiding process 10, where the program is read and processed by a processor, in order to execute and realize the steps of the parking space guiding process 10. Otherwise, please refer to FIG. 4, which is a schematic diagram of a parking space guiding device 40 according to an embodiment of the present invention. The parking space guiding device 40 can be utilized in a vehicle, for guiding parking space. As shown in FIG. 4, the parking space guiding device 40 includes a decoding unit 400, a processing unit 402, a sensing unit 404, an indicating unit 406 and a screen 408. The decoding unit 400 is utilized for obtaining location information of a parking space. The processing unit 402 is utilized for calculating a destination position according to the location information. The sensing unit 404 is utilized for determining a movement of the vehicle to generate a determination result. The indicating unit 406 is utilized for generating a guiding indication for guiding the vehicle to the destination position according to the determination result. In short, after obtaining the location information of the parking space (e.g. decoding a QR code to obtain the location information of the parking space), the decoding unit 400 may send the location information to the processing unit 402, such that the processing unit 402 can calculate the destination position of the parking space. After determining the direction and distance of the movement of the vehicle, the sensing unit 404 sends the information to the processing unit 402. The processing unit 402 then calculates the relationship between the movement of the vehicle and the destination position, and outputs an indication signal to the indicating unit 406, such that the indicating unit 406 can display the direction guiding indication corresponding to the indication signal on the screen 408. The detailed operations of the parking space guiding device 40 are illustrated above, and will not be narrated herein.

To sum up, according to the embodiment of the present invention, after the parking space information is obtained, the sensor together with the camera can guide the vehicle to the accurate location of parking space, such that the time for the driver to find the parking space can be reduce. In addition, the embodiment of the present invention can be used for solving the problem of poor signal reception indoors, so as to avoid guiding failure.
