Description
Technical Field
[0001] The present invention relates to a parking space number recording method and system thereof, in particular to a method and system thereof for automatically recording and transmitting parking space numbers. Background Art
[0002] Cars are one of the indispensable means of transportation in people's lives today. As the number of cars continues to increase, multi-story and large-area parking lots are designed to meet the parking needs of a large number of cars. For the convenience of management, parking spaces in parking lots are numbered and marked at the location of the parking space (for example, on the ground). For example, the parking space number is "A001", where the English letter "A" means that the parking area is in area A, and the number "001" indicates the parking space number.
[0003] However, the parking space numbers mentioned above vary with the management methods of different parking lots, and various types of numbers are generated. Some parking space numbers are long and complex, and are not easy for drivers to remember, which may cause the driver to forget where the vehicle is parked. Summary of the invention
[0004] Although, in the current management method of some parking lots, when the vehicle enters the parking lot to collect the ticket, the license plate number of the vehicle will be photographed by a camera installed at the entrance of the parking lot, and when the vehicle is parked in the parking space, the parking space number will be photographed again by a camera installed near the parking space and recorded in the management system. When the driver goes to the payment machine to pay the fee, the parking space number is displayed on the payment machine screen to solve the above-mentioned problem that the driver forgets where the vehicle is parked. However, the above-mentioned method requires the installation of multiple cameras in various places in the parking lot. When the number of floors of the parking lot increases and the floor area is larger, the number of cameras that need to be installed will also increase, thereby increasing the construction cost and management cost of the parking lot. In addition, if the driver drives the vehicle into some parking lots that do not have the above-mentioned management method, the driver still needs to remember the parking space number by himself, so the problem of the driver forgetting where the vehicle is parked will still occur.
[0005] To solve the above problems, the present invention aims to provide a method for automatically recording and transmitting parking space numbers, which is executed by a system for automatically recording and transmitting parking space numbers, and includes the following steps: determining whether the vehicle speed information of a vehicle is lower than a set value; when it is confirmed that the vehicle speed information is lower than the set value, obtaining a portion of a plurality of vehicle surrounding images according to the gear information of the vehicle; establishing a parking space recognition model according to the plurality of vehicle surrounding images, and recognizing a plurality of characters corresponding to the portion of the vehicle surrounding images; grouping the plurality of characters to form a plurality of groups of parking space numbers corresponding to the portions of the vehicle surrounding images; determining the priority of the plurality of groups of parking space numbers; and after the vehicle is turned off, transmitting the parking space number with the highest priority among the plurality of groups of parking space numbers to a user end.
[0006] In some embodiments, the plurality of characters are grouped by using the distance between the characters.
[0007] In some embodiments, the priority of the plurality of parking space numbers is determined based on the number of times a portion of the vehicle's surrounding image is recognized.
[0008] In some embodiments, the priority of the plurality of parking space numbers is determined based on the installation position of the vehicle camera module used in the partial vehicle surrounding image.
[0009] In some embodiments, the priority of the plurality of parking space numbers is determined based on the time when the images of the surroundings of the vehicle are captured.
[0010] To solve the above problems, the present invention aims to provide a system for automatically recording and transmitting parking space numbers, comprising: a vehicle speed sensing module for sensing the driving speed of a vehicle to obtain vehicle speed information; a gear position sensing module for sensing the gear position of the vehicle to obtain gear position information; a vehicle camera module installed on the vehicle to obtain a plurality of vehicle surrounding images; an artificial intelligence module connected to the vehicle camera module to establish a parking space recognition model based on the plurality of vehicle surrounding images, and to recognize a plurality of characters corresponding to a portion of the plurality of vehicle surrounding images; a character grouping module connected to the artificial intelligence module to group the plurality of characters to form a plurality of groups of parking space numbers corresponding to the portions of the vehicle surrounding images; a control module connected to the vehicle speed sensing module, the gear position sensing module, the vehicle camera module, the character grouping module and the artificial intelligence module to determine the priority of the plurality of groups of parking space numbers; and a communication module connected to the control module to transmit the parking space number with the highest priority among the plurality of groups of parking space numbers to a user end.
[0011] In some embodiments, the character grouping module groups the plurality of characters using distances between the characters.
[0012] In some embodiments, the priority of the plurality of parking space numbers is determined based on the number of times they are recognized in a portion of the vehicle's surrounding image.
[0013] In some embodiments, the priority order of the plurality of parking space numbers is determined based on the installation position of the vehicle camera module used in the partial vehicle surrounding image.
[0014] In some embodiments, the priority of the plurality of parking space numbers is determined based on the time when the portion of the vehicle surrounding image is captured.
[0015] In summary, the method and system for automatically recording and transmitting parking space numbers of the present invention can determine the priority order according to the number of times the parking space number is recognized in the image around the vehicle, the time when it is photographed, or the installation position of the vehicle camera module, and after the vehicle is turned off, the parking space number with the highest priority order is transmitted to the user end via the communication module to solve the problem that the driver forgets where the vehicle is parked. In addition, the control module can obtain part of the image around the vehicle according to the gear information to reduce the amount of data of the image around the vehicle input to the control module, thereby reducing the calculation load of the control module, and thus relatively improving the calculation efficiency of the control module.

[0043] Please refer to Figure 1, is a block diagram of a system for automatically recording and transmitting parking space numbers according to an embodiment of the present invention. The system 100 for automatically recording and transmitting parking space numbers can be installed on a vehicle 150. The system 100 for automatically recording and transmitting parking space numbers includes: a vehicle speed sensing module 10, a gear position sensing module 20, a vehicle camera module 30, an artificial intelligence module 40, a control module 50, and a communication module 60. The system 100 for automatically recording and transmitting parking space numbers can transmit the parking space number to the user end 200 through the communication module 60. In other embodiments, the system 100 for automatically recording and transmitting parking space numbers can also be connected to the Internet (not shown) through the communication module 60, and the user end 200 can be connected to the Internet. In this way, the system 100 for automatically recording and transmitting parking space numbers can transmit the parking space number to the user end 200 through the Internet. The user end 200 can be, for example, a handheld mobile communication device (e.g., a smart phone) or a wearable electronic device (e.g., a smart watch), but is not limited thereto.
[0044] The vehicle speed sensing module 10 is connected to the control module 50. The vehicle speed sensing module 10 is used to sense the driving speed of the vehicle 150 to obtain vehicle speed information. The vehicle speed sensing module 10 can be, for example, a wheel speed sensor or an axle speed sensor, but is not limited thereto. For example, the vehicle speed sensing module 10 can be connected to the wheels of the vehicle 150 to sense the rotation speed of the wheels to obtain vehicle speed information. In other embodiments, the vehicle speed sensing module 10 can be connected to the output shaft of the gearbox to sense the rotation speed of the output shaft to obtain vehicle speed information.
[0045] The gear position sensing module 20 is connected to the control module 50. The gear position sensing module 20 is used to sense the gear position of the vehicle 150 to obtain gear position information. The gear position sensing module 20 can be, for example, a contact gear position sensor or a non-contact gear position sensor. For example, the gear position sensing module 20 can be connected to the gear mechanism of the vehicle 150 and sense the mechanical position change of the gear mechanism to obtain the gear position information. In other embodiments, the gear position sensing module 20 can use magnetic induction to sense the mechanical position change of the gear mechanism to obtain the gear position information. In other embodiments, the gear position sensing module 20 can use photoelectric induction to sense the mechanical position change of the gear mechanism to obtain the gear position information. The gear position information may include: P gear (i.e. parking gear), R gear (i.e. reverse gear), N gear (i.e. neutral gear), D gear (i.e. forward gear), 3rd gear, 2nd gear and 1st gear, but is not limited thereto.
[0046] The vehicle camera module 30 is connected to the artificial intelligence module 40 and the control module 50. The vehicle camera module 30 is installed on the vehicle 150. The vehicle camera module 30 can capture images of the surroundings (e.g., front, left, right and / or rear, etc.) of the vehicle 150 in horizontal and vertical perspectives to obtain images of the surroundings of the vehicle. The vehicle camera module 30 can be, for example, a wide-angle camera, but is not limited thereto. The vehicle camera module 30 in this example is composed of a plurality of wide-angle cameras. In other embodiments, the vehicle camera module 30 can also be composed of one wide-angle camera.
[0047] For example, see Figure 2 , is a schematic diagram of the installation position of the vehicle camera module 30 of the system 100 for automatically recording and transmitting parking space numbers according to an embodiment of the present invention. The camera module 30 may include a front vehicle camera 31, a side vehicle camera 32, a side vehicle camera 33, and a rear vehicle camera 34. The front vehicle camera 31 is installed at the front of the vehicle 150 to capture images in front of the vehicle 150. The side vehicle camera 32 is installed at the right side of the vehicle 150 to capture images on the right side of the vehicle 150. The side vehicle camera 33 is installed at the left side of the vehicle 150 to capture images on the left side of the vehicle 150. The rear vehicle camera 34 is installed at the rear of the vehicle 150 to capture images behind the vehicle 150. In other embodiments, the number of vehicle camera modules 30 may be increased or decreased, and the installation position (e.g., roof and / or bottom of the vehicle) may be adjusted.
[0048] The artificial intelligence module 40 receives a plurality of vehicle surrounding images from the vehicle camera module 30 to establish a parking space recognition model based on the plurality of vehicle surrounding images, and recognizes a plurality of characters corresponding to a portion of the vehicle surrounding images of the plurality of vehicle surrounding images according to the parking space recognition model. In some embodiments, the artificial intelligence module 40 may use a deep learning object detection method to pre-input and train a large number of images containing parking space numbers to establish a parking space recognition model. The artificial intelligence module 40 may recognize objects based on a neural network algorithm (e.g., YOLO), a region-based convolutional neural network (R-CNN) or a fast R-CNN), but is not limited thereto. The artificial intelligence module 40 may be stored in a non-volatile memory (e.g., a solid state drive (SSD), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), a read-only memory (ROM), etc.) to provide the control module 50 with the data required for reading or writing.
[0049] The character grouping module 42 is connected to the artificial intelligence module 40. The character grouping module 42 uses a grouping algorithm to group the multiple characters recognized by the artificial intelligence module 40 to form multiple groups of parking space numbers corresponding to the images of the surrounding parts of the vehicle. In other words, the character grouping module 42 is equivalent to a post-processing program for data processing, which can combine multiple characters into one or more parking space numbers. In the process of grouping multiple characters, the distance between each character can be used for grouping.
[0050] The control module 50 is connected to the vehicle speed sensing module 10, the gear position sensing module 20, the vehicle camera module 30, the artificial intelligence module 40, the character grouping module 42 and the communication module 60. The control module 50 is used to determine whether to identify a portion of the vehicle surrounding image to obtain multiple parking space numbers based on the vehicle speed information from the vehicle speed sensing module 10 and the gear position information from the gear position sensing module 20. The control module 50 can also be used to determine the priority of multiple parking space numbers. In some embodiments, the control module 50 can determine the priority based on the number of times the multiple parking space numbers are identified in a portion of the vehicle surrounding images of the multiple vehicle surrounding images. For example, the priority is determined to be the highest for the multiple parking space numbers that are identified the most times in a portion of the vehicle surrounding images of the multiple vehicle surrounding images. In other embodiments, the control module 50 determines the priority based on the installation position of the vehicle camera module 30 used in the multiple parking space numbers in a portion of the vehicle surrounding images of the multiple vehicle surrounding images. For example, the priority is determined to be the highest based on the image of the vehicle surroundings captured by the front vehicle camera 31 or the rear vehicle camera 34. In other embodiments, the control module 50 determines the priority based on the time when the multiple parking space numbers are captured in a part of the vehicle surrounding images of the multiple vehicle surrounding images. For example, the priority is determined to be the highest based on the longest time when the multiple parking space numbers are captured in a part of the vehicle surrounding images of the multiple vehicle surrounding images. In other embodiments, the control module 50 may determine the priority to be the highest based on the latest time (for example, close to the current time) when the multiple parking space numbers are captured in a part of the vehicle surrounding images of the multiple vehicle surrounding images. After the vehicle 150 is turned off, the control module 50 transmits the parking space number with the highest priority among the multiple parking space numbers to the communication module 60. The control module 50 may be, for example, a general-purpose or special-purpose microprocessor, a field programmable gate array (FPGA), an application-specific integrated circuit (ASIC), a neural network accelerator or other similar components or a combination of the above components.
[0051] The communication module 60 is used to transmit the parking space number with the highest priority among the multiple parking space numbers from the control module 50 to the user end 200. The communication module 60 can use wireless communication transmission to transmit the information including the parking space number to the user end 200, but is not limited thereto. The communication module 60 can support Bluetooth communication standards, WiFi communication standards, Zigbee communication standards, fourth generation (4G) cellular communication standards or fifth generation (5G) cellular communication standards, but is not limited thereto. In other embodiments, the communication module 60 can also use wired communication transmission to transmit the information including the parking space number to the user end 200.
[0052] Please refer to Figure 3 1 is a flowchart of a method for automatically recording and transmitting parking space numbers executed by the system 100 for automatically recording and transmitting parking space numbers according to an embodiment of the present invention. Figure 3 The steps may be performed by the system 100 which automatically records and transmits the parking space number.
[0053] In step S200, the control module 50 determines whether the vehicle speed information from the vehicle speed sensing module 10 is lower than the set value. The set value may be, for example, 3 km / h to 8 km / h, but is not limited thereto. The control module 50 may compare the vehicle speed information obtained by the vehicle speed sensing module 10 with the set value to confirm whether the current driving speed of the vehicle 150 is lower than the set value. When the judgment is "no", that is, the vehicle speed information is greater than or equal to the set value, the process re-performs step S200, so that the control module 50 continues to determine whether the vehicle speed information of the vehicle 150 is lower than the set value. When the judgment is "yes", the process proceeds to step S210.
[0054] In step S210, the control module 50 obtains a portion of the plurality of vehicle surrounding images according to the gear information from the gear sensing module 20 and outputs the images to the artificial intelligence module 40. For example, when the gear information is D gear, the control module 50 may only obtain the vehicle surrounding images captured by the front vehicle camera 31 and the side vehicle cameras 32 and 33, but not the vehicle surrounding images captured by the rear vehicle camera 34. Since when the gear information is D gear, it can be determined that the vehicle 150 is not ready to park in the parking space (i.e., it is still in the state of searching for a parking space), therefore, the vehicle surrounding images obtained by the rear vehicle camera module 34 are of "no" or "very low" help to the operation procedure of identifying the parking space number, so the control module 50 may not need to include the vehicle surrounding images obtained by the rear vehicle camera 34 in the operation procedure of identifying the parking space number, so as to reduce the operation load of the control module 50. In other embodiments, when the gear position information is the D gear, only the vehicle surrounding images from the front vehicle camera 31 are obtained, while the vehicle surrounding images from the rear vehicle camera 34 and the side vehicle cameras 32 and 33 are not obtained.
[0055] In step S220, the artificial intelligence module 40 uses the parking space recognition model to recognize a portion of the plurality of vehicle surrounding images obtained from the control module 50 to generate a plurality of characters corresponding to the portion of the vehicle surrounding images and output them to the character grouping module 42. The artificial intelligence module 40 can cut, analyze and recognize a portion of the plurality of vehicle surrounding images to obtain a plurality of characters including text, numbers and / or symbols. In other embodiments, the characters may also include patterns.
[0056] In step S230, the character grouping module 42 groups the multiple characters to form multiple groups of parking space numbers corresponding to parts of the vehicle surrounding image and outputs the groups to the control module 50. The multiple characters may be grouped according to the distance between the characters.
[0057] In step S240, the control module 50 determines the priority of the plurality of parking space numbers. In some embodiments, the priority can be determined based on the number of times the plurality of parking space numbers are recognized in the partial vehicle surrounding images. Since the more times the plurality of parking space numbers are recognized, the more likely the vehicle 150 has selected the final parking space position, the number of times the plurality of parking space numbers are recognized is used as a judgment condition. In some embodiments, the priority can be determined based on the installation position of the vehicle camera module used in the partial vehicle surrounding images. Since the vehicle 150 usually parks in the parking space in a straight or reverse manner, the installation position of the vehicle camera (for example, the front vehicle camera 31 or the rear vehicle camera 34) can be used as a judgment condition. In some embodiments, since each vehicle surrounding image records the shooting time information of the image, the control module 50 can determine the order of each vehicle surrounding image according to the shooting time information. The control module 50 determines the priority of the plurality of parking space numbers based on the plurality of shooting time information of the partial vehicle surrounding images corresponding to the plurality of parking space numbers. In some embodiments, the control module 50 determines the priority order to be the highest according to the longest time that the multiple parking space numbers are captured in the images around the vehicle. For example, when the vehicle 150 is parked in the parking space and before the engine is turned off, the parking space number captured by the vehicle camera module 30 for the longest time can be determined to represent the last parking position. Therefore, the control module 50 sets the priority order of this parking space number to be the highest. In other embodiments, the control module 50 can determine the priority order to be the highest according to the latest time that the multiple parking space numbers are captured in the images around the vehicle.
[0058] Step S250, the control module 50 confirms whether the vehicle 150 is turned off? For example, the control module 50 can confirm whether the vehicle 150 is turned off according to the flameout signal generated by the internal judgment circuit of the vehicle 150 after the driver presses the flameout button, or the control module 50 can confirm whether the vehicle 150 is turned off according to the power-off signal generated by the internal judgment circuit of the vehicle 150 (taking an electric car as an example) after the driver presses the flameout button, but it is not limited to the above method. When the judgment is "no", the process returns to step S200. When the judgment is "yes", the process proceeds to step S260.
[0059] In step S260, the control module 50 transmits the parking space number with the highest priority among the plurality of parking space numbers to the user end 200 through the communication module 60. In other embodiments, the control module 50 may also determine whether to transmit the parking space number with the highest priority among the plurality of parking space numbers to the user end 200 through the communication module 60 according to the "P gear" of the gear information.
[0060] Please refer to Figure 4A , is a schematic diagram of the system 100 for automatically recording and transmitting parking space numbers according to an embodiment of the present invention obtaining images around the vehicle. When the gear information is the D gear, the control module 50 can only obtain the images around the vehicle corresponding to the first image range 310 captured by the front vehicle camera 31 and the side vehicle cameras 32 and 33, and does not obtain the images around the vehicle corresponding to the second image range 340 captured by the rear vehicle camera 34. By reducing the amount of data of the vehicle's surrounding images input to the control module 50, the calculation load of the control module 50 is reduced, thereby relatively improving the calculation efficiency of the control module 50.
[0061] Please refer to Figure 4B , is another schematic diagram of the system 100 for automatically recording and transmitting parking space numbers according to an embodiment of the present invention obtaining vehicle surrounding images. When the gear information is the R gear, the control module 50 may only obtain the vehicle surrounding images corresponding to the second image range 340 captured by the rear vehicle camera 34, and not obtain the vehicle surrounding images corresponding to the first image range 310 captured by the front vehicle camera 31 and the side vehicle cameras 32 and 33. In other embodiments, it is also possible to only obtain the vehicle surrounding images corresponding to the image range captured by the side vehicle camera 32 or the side vehicle camera 33, and not obtain the vehicle surrounding images corresponding to the second image range 340 captured by the rear vehicle camera 34 and / or the vehicle surrounding images corresponding to the image range captured by the front vehicle camera 31. Similarly, the above-mentioned method of obtaining a part of the vehicle surrounding images among the plurality of vehicle surrounding images can reduce the amount of vehicle surrounding image data input to the control module 50, thereby reducing the calculation load of the control module 50, and thereby relatively improving the calculation efficiency of the control module 50.
[0062] Please refer to Figure 5A and Figure 5B , is a schematic diagram of the parking space number recognition process according to an embodiment of the present invention. Figure 5A As shown, the vehicle 150 travels in the direction indicated by the arrow. When the vehicle 150 passes through the parking space, the control module 50 obtains a portion of the vehicle surrounding images through the vehicle camera module 30 according to the gear information. Then, the artificial intelligence module 40 recognizes the character 500 as "A", the character 510 as "0", the character 520 as "0", and so on according to the aforementioned portion of the vehicle surrounding images. Finally, the content of the multiple characters obtained is "AAA000000123". The artificial intelligence module 40 outputs the recognized characters to the character grouping module 40.
[0063] like Figure 5B As shown, the character grouping module 40 can group multiple characters using a grouping algorithm and output them to the control module 50. For example, multiple characters are grouped according to the distance d between each character to form parking space numbers 600, 610, and 620. Since each vehicle surrounding image records the shooting time information, the control module 50 can determine the order of each vehicle surrounding image according to the shooting time information. When the vehicle 150 passes the parking space number 620, since the time of the parking space number 620 captured by the vehicle camera module 30 is the longest (i.e., the first vehicle surrounding image captured), and the time of the parking space number 610 captured by the vehicle camera module 30 is the second longest, and the time of the parking space number 600 captured by the vehicle camera module 30 is the shortest (i.e., the last vehicle surrounding image captured). Therefore, the parking space number 620 is temporarily set by the control module 50 to have the first priority, the parking space number 610 is set by the control module 50 to have the second priority, and the parking space number 600 is set by the control module 50 to have the third priority. The first priority is higher than the second priority, and the second priority is higher than the third priority.
[0064] When the vehicle 150 continues to drive to the parking space number 600, since the time of the parking space number 600 photographed by the vehicle camera module 30 is the latest, the time of the parking space number 610 photographed by the vehicle camera module 30 is the second latest, and the time of the parking space number 620 photographed by the vehicle camera module 30 is the latest. Therefore, the parking space number 600 is temporarily set by the control module 50 to have the first priority, the parking space number 610 is set by the control module 50 to have the second priority, and the parking space number 620 is set by the control module 50 to have the third priority.
[0065] When the vehicle 150 finally chooses to park at the parking space number 600 and turns off the engine, the control module 50 sets the parking space number 600 with the first priority and transmits it to the user end 200 (e.g., a smart phone) via the communication module 60 in the form of information. In this way, the driver can check the above information through the smart phone to know the parking space number 600 where the vehicle 150 is parked, so as to solve the problem that the driver forgets where the vehicle is parked. In addition, in other embodiments, the control module 50 can also determine the priority according to the number of times the parking space number in the image around the vehicle is recognized or the installation position of the vehicle camera module used.
[0066] In summary, the method and system for automatically recording and transmitting parking space numbers of the present invention can determine the priority order according to the number of times the parking space number is recognized in the vehicle surrounding image, the time when it is photographed, or the installation position of the vehicle camera module, and after the vehicle 150 is turned off, the parking space number with the highest priority order is transmitted to the user end via the communication module 60 to solve the problem that the driver forgets where the vehicle 150 is parked. In addition, the control module 50 can obtain part of the vehicle surrounding image according to the gear information to reduce the amount of data of the vehicle surrounding image input to the control module 50, thereby reducing the calculation load of the control module 50, and thus relatively improving the calculation efficiency of the control module 50.
