Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Because the reserved quantity of the automobiles in the city is large, and the space available for parking is small, the distance between the automobiles in the parking area is small, and the operation of a user is difficult in the process of parking and warehousing. Therefore, a vehicle equipped with an automatic parking function is popular.
When a vehicle is parked automatically, an image of an available parking space is acquired by an image acquisition device (such as a camera) mounted on the vehicle, and position information between the vehicle and the available parking space, size information of the parking space, and the like are acquired by identifying a parking space line in the image. And then, planning a driving path according to the information and controlling the vehicle to park in the available parking space. Therefore, the recognition of the vehicle to the parking space line is a key ring for realizing automatic parking, and therefore, the recognition function of the vehicle to the parking space line needs to be tested in the vehicle development process.
In the related art, a target parking space meeting the test requirement needs to be found before testing, and then a vehicle to be tested is driven to the target parking space for testing. For example, in the cell a, a target parking space meeting the test condition is available, and a vehicle to be tested needs to be driven to the cell a by a vehicle manufacturing company for testing. When different types of target parking spaces need to be tested, vehicles to be tested need to be driven to different places in sequence for testing. The testing process is time consuming and labor intensive.
In view of this, the present application provides an automatic parking assistant testing device, where a projection device is installed on a support so that the support is higher than the ground, the projection device can project a parking space line on the ground, and a vehicle to be tested tests a recognition function of the vehicle on the parking space line by recognizing the projected parking space line. In the test process, the vehicles to be tested do not need to be driven to different places, so that the test difficulty and the labor intensity are reduced.
The following describes the automatic parking assistance test apparatus provided in the present application in detail with reference to the accompanying drawings.
As shown in fig. 1 to 3, the automatic parking assistance test apparatus provided by the present application includes a rack and a projection apparatus 100.
The projection device 100 faces the ground 400 and is used for projecting a parking space line on the ground 400, wherein the parking space line is used for identifying vehicles to be tested. Here, projecting the parking space line on the ground 400 means that the projection device 100 projects an image of the parking space line on the ground 400, and does not generate a physical parking space line on the ground 400. The type of the projection apparatus 100 is not limited in the present application, as long as the vehicle line can be projected on the floor 400. The internal structure and operation principle of the projection apparatus 100 can be referred to in the prior art.
The parking space line image may be built in the projection device 100, or may be read from the outside when the projection device 100 is operated. For example, the projection apparatus 100 has a USB data interface, and a USB disk storing the lane images is inserted into the USB data interface of the projection apparatus 100, so that the lane images in the USB disk can be read when the projection apparatus 100 is in operation. For another example, the projection device 100 is connected to the control device 300 through a data line, a parking space line image is stored in the control device 300, and the control device 300 transmits the parking space line image to the projection device 100 so that the projection device 100 projects a parking space line on the ground 400. The present application does not limit the manner in which the projection apparatus 100 acquires the parking lane image.
The power supply of the projection apparatus 100 during operation may be provided by a battery or by connecting to an external power source, which is not described herein again.
The support serves as a framework of the automatic parking assistant testing device and is used for supporting and connecting other parts (such as the projection device 100). The stand includes a fixing portion 211 coupled to the ground 400 and a mounting portion for supporting and coupling the projection apparatus 100.
The installation part is higher than the ground 400 after being connected with the installation part by a preset height from the ground 400, so that the projection device 100 can conveniently project the vehicle leaving line on the ground 400. Generally, the farther the projection apparatus 100 is from the ground 400, the larger the projected image, and the closer the projection apparatus 100 is to the ground 400, the smaller the projected image. Therefore, the preset height may be determined according to the performance of the projection apparatus 100, as long as it is ensured that the position line projected by the projection apparatus 100 is the same as or similar to the actual position line.
The fixing portion 211 is connected to the ground 400, and the mounting portion is connected to the fixing portion 211 so that the mounting portion is fixed with respect to the ground 400. The fixing portion 211 may be movably placed on the ground 400, or may be fixedly connected to the ground 400 by an expansion bolt, etc. For example, when the test site is fixed, the fixing portion 211 may be fixedly attached to the test site; when the test position is not fixed, the fixing portion 211 may be movably placed on the floor 400 to facilitate replacement of the test position.
The automatic parking auxiliary testing device comprises a projection device 100 and a support, wherein the projection device 100 is fixed at a certain height above the ground 400 through the support, the projection device 100 projects a parking space line on the ground 400 during testing, and a vehicle to be tested identifies the parking space line projected on the ground 400, so that the automatic parking function of the vehicle to be tested is tested. Compared with the prior art that a target parking space needs to be searched before testing, and a vehicle to be tested is driven to the target parking space, the automatic parking auxiliary testing device provided by the application can simulate a parking space line in a projection mode, and further realizes the testing of an automatic parking function. The target parking space does not need to be searched, and the vehicle to be tested does not need to be driven to the target parking space, so that the testing difficulty and workload are reduced.
In the practical application process, on one hand, the car position lines are different in size, color and shape, and in order to ensure normal use of the automatic parking function, the recognition capability of the car to different car position lines needs to be tested respectively. On the other hand, the parking space lines in the same area are generally the same, and the parking space lines in different areas may be different. For example, the parking space lines of the same cell are the same, while the parking space lines may be different between different cells. Therefore, different vehicle location lines need to be searched for in different cells respectively in the test process so as to test the recognition capability of the vehicle on the different vehicle location lines, and time and labor are wasted.
Optionally, in some embodiments, the automatic parking assistance testing apparatus further includes a control device 300, the control device 300 is electrically connected to the projection device 100, and the control device 300 is configured to control the projection device 100 to project different parking space lines on the ground 400. Therefore, different parking positions can be simulated through the automatic parking auxiliary testing device to test the recognition capability of the vehicle to different parking positions, namely, the test to different parking positions can be realized at the same position without respectively testing to different places, and the test workload is reduced.
The control device 300 may be installed on the ground 400 or on a stand.
Optionally, in some embodiments, the projection apparatus 100 includes a first projection apparatus 110 and a second projection apparatus 120, the first projection apparatus 110 and the second projection apparatus 120 are spaced apart along a horizontal direction, and the first projection apparatus 110 is used for projecting a first parking space angle 111 of the parking space line and the second projection apparatus 120 is used for projecting a second parking space angle 121 of the parking space line.
Since the farther the projection apparatus 100 is from the ground 400, the larger the projected image, and the closer the projection apparatus 100 is from the ground 400, the smaller the projected image. Therefore, if all required parking spaces are projected by one projection device 100, the height of the projection device 100 from the ground 400, that is, the height of the support, needs to be set higher, which not only reduces the stability of the support, but also reduces the mobility of the support.
The first projection device 110 projects the first position angle 111 of the position line, and the second projection device 120 projects the second position angle 121 of the position line, that is, each projection device 100 projects a part of the position line, so that the requirement for the installation height of the projection devices 100 can be reduced, and the height of the support can be reduced.
Of course, the projection apparatus 100 may further include a third projection apparatus 100, a fourth projection apparatus 100, and the like, which is not limited in this application.
