[0038] Please refer to Figures 1 to 7The present application provides a road real-scene test light box device, which includes a bracket 10, a box 20, a real-scene model 30, a light source assembly 40 and a motion assembly. The box 20 is connected to the bracket 10, and the box 20 has a first side surface and a second side surface that are opposite to each other in a first direction, and an opening is provided on the first side surface. The real-scene model 30 is arranged inside the box 20 to simulate a real road environment. The light source assembly 40 includes a light source box 41, a simulated sunlight light source 43 and a multi-color temperature light source 42. The light source box 41 is arranged on the second side surface and connected to the bracket 10. The simulated sunlight light source 43 and the multi-color temperature light source 42 are arranged inside the light source box 41, and the simulated sunlight light source 43 and the multi-color temperature light source 42 are used to simulate the emission of sunlight and multi-color temperature light to the inside of the box 20, respectively. The motion assembly includes a first support platform 50, a second support platform 60, and a first linear motion module 140 and a second linear motion module 150 connected side by side on the bracket 10 along a first direction. The first linear motion module 140 and the second linear motion module 150 are located below the box 20. The first linear motion module 140 and the second linear motion module 150 are respectively connected to the first support platform 50 and the second support platform 60 so as to drive the first support platform 50 and the second support platform 60 to move alternately back and forth.
[0039] For example, the real scene model 30 is used to simulate a traffic road close to the real one inside the box 20, so that the vehicle-mounted camera 80 can perform in a more realistic road scene. In addition, the real scene model 30 may include a tunnel 34, a sidewalk 33, a driving road, a traffic light, a billboard, pedestrians, etc., which may be added according to the test requirements.
[0040] Exemplarily, the simulated solar light source 43 is used to simulate sunlight irradiating the interior of the box 20, and the road traffic at different time periods can be simulated by controlling the illumination intensity and illumination angle of the sunlight emitted by the simulated solar light source 43, so as to ensure that the vehicle-mounted camera 80 is tested in a more realistic road environment. For example, if the illumination intensity of sunlight irradiating on the road is relatively high at noon, the illumination intensity of the simulated solar light source 43 is controlled to be increased; if the illumination intensity of sunlight irradiating on the road is relatively low in the morning, the illumination intensity of the simulated solar light source 43 is controlled to be reduced.
[0041] Exemplarily, the multi-color temperature light source 42 is used to emit light of multiple color temperatures to the interior of the box 20, so as to provide fill light for the real-scene model 30 inside the box 20, thereby simulating the real road scene under different lighting environments and ensuring the accuracy of the vehicle-mounted camera 80 test.
[0042] Exemplarily, the first linear motion module 140 and the second linear motion module 150 are respectively used to drive the first support platform 50 and the second support platform 60 to perform linear motion, so that the car model 70 and the vehicle camera 80 placed on the first support platform 50 and the second support platform 60 move forward and backward in traffic to simulate the vehicle driving on the road. In addition, the first linear motion module 140 and the second linear motion module 150 can control their running speeds through a controller to simulate different vehicle speed states of the car and test the performance of the vehicle camera 80 in identifying or shooting under different vehicle speed states. It should be noted that the first linear motion module 140 and the second linear motion module 150 can adopt linear motion components commonly used in the prior art, and the specific details are not repeated.
[0043] Exemplarily, the first loading platform 50 and the second loading platform 60 are used to place the car model 70 and the vehicle camera 80 to be tested, respectively. Specifically, the first loading platform 50 can be used to place the car model 70, and the second loading platform 60 can be used to place the vehicle camera 80 to be tested. Alternatively, the first loading platform 50 can be used to place the vehicle camera 80 to be tested, and the second loading platform 60 can be used to place the car model 70. However, for ease of description, this embodiment is described by taking the first loading platform 50 for placing the car model 70 and the second loading platform 60 for placing the vehicle camera 80 to be tested as an example.
[0044] The road real-scene test light box device based on the above-mentioned technical features places a real-scene model 30 inside the box 20, and cooperates with the simulated sunlight light source 43 and the multi-color temperature light source 42 to emit light to the inside of the box 20, so that the real-scene model 30 simulates real road scenes in different environments under the irradiation of different lighting, and then drives the first linear motion module 140 and the second linear motion module 150 to drive the first load platform 50 and the second load platform 60 to move back and forth alternately, thereby simulating the situation of a car driving on a real road, so that the vehicle-mounted camera 80 can capture the corresponding image or video. It has a simple structure and a high degree of integration. It can be adjusted accordingly according to different test requirements, which is closer to the performance test of the vehicle-mounted camera 80 in the real world scene.
[0045] In a possible implementation, a background plate 160 is further included. The background plate 160 is disposed on the second side and located between the light source box 41 and the box body 20 . The background plate 160 is used to simulate a real background under the illumination of the simulated sunlight light source 43 and the multi-color temperature light source 42 .
[0046] Exemplarily, the background board 160 is disposed on the second side and is located between the light source box 41 and the box body 20, so that the light emitted from the simulated sunlight light source 43 or the multi-color temperature light source 42 in the light source box 41 is irradiated on the background board 160, so that the patterns of the sun, moon, stars, etc. on the background board 160 are displayed above the real scene model 30, thereby simulating a sky environment close to the real thing.
[0047] In a possible embodiment, the real-life model 30 is provided with a tunnel 34 and a first driving lane 31 and a second driving lane 32 arranged side by side along a first direction. The first driving lane 31 and the second driving lane 32 both run through the tunnel 34. A sidewalk 33 crossing the first driving lane 31 and the second driving lane 32 is provided in front of the exit of the tunnel 34. The first load platform 50 and the second load platform 60 can move back and forth along the first driving lane 31 and the second driving lane 32, respectively.
[0048] For example, the first driving lane 31 and the second driving lane 32 are set in the real-life model 30, and the lower ends of the first supporting platform 50 and the second supporting platform 60 pass through the bottom of the box 20 to connect with the first linear motion model and the second linear motion model, so that the first supporting platform 50 and the second supporting platform 60 move along the first driving lane 31 and the second driving lane 32 under the action of the first linear motion model and the second linear motion model to simulate the situation that the vehicle is driving on the same or opposite roads. In addition, the first driving lane 31 and the second driving lane 32 are passed through the tunnel 34 in order to simulate the imaging effect of the vehicle camera 80 shooting when the vehicle is driving in the tunnel 34, so as to test the performance of the vehicle camera 80.
[0049] In a possible implementation, the first clamping member and the second clamping member 180 are further included, and the first clamping member and the second clamping member 180 are respectively used to detachably connect the first carrier 50 and the second carrier 60 to the first linear motion module 140 and the second linear motion module 150. In this way, the first carrier 50 and the second carrier 60 are detachably connected to the first linear motion module 140 and the second linear motion module 150 by using the first clamping member and the second clamping member 180, respectively, to ensure that the first carrier 50 and the second carrier 60 will not fall when being driven to move, thereby affecting normal testing, and can also be replaced according to the size of the car model 70 and the fixture 170 to be carried.
[0050] In a possible implementation, the first clamping member and the second clamping member 180 have the same structure. The second clamping member 180 includes a sliding frame 181 and a clamping plate 182, the sliding frame 181 is slidably connected to the second linear motion module 150, the clamping plate 182 is fixedly connected to the lower end of the second bearing platform 60, and the clamping plate 182 is detachably connected to the sliding frame 181.
[0051] It should be noted that the connection between the clamping plate 182 and the lower end of the first supporting platform 50 can be detachable or integrally formed, and there is no limitation on this.
[0052] For example, since the sliding frame 181 is slidably connected to the first linear motion module 140, and the clamping plate 182 is connected to the sliding frame 181, when the first linear motion module 140 drives the sliding frame 181 to move along the first direction, the clamping plate 182 is driven to move back and forth, thereby driving the first bearing platform 50 to move, so that the car model 70 placed on the first bearing platform 50 can be driven to move, simulating the state of the car driving. In addition, the speed of the first bearing platform 50 can be adjusted by controlling the running speed of the first linear motion module 140, so that the speed of the car model 70 can be adjusted according to the test requirements, with a simple structure and convenient adjustment.
[0053] It should be noted that, since the first clamping member and the second clamping member 180 have the same structure, the specific structure of the second clamping member 180 may refer to the structure of the first clamping member, and will not be described in detail.
[0054] In a possible implementation, the box 20 includes a frame 21 and a plurality of enclosures 22 . The frame 21 is fixedly connected to the bracket 10 , and the plurality of enclosures 22 are connected to multiple surfaces of the frame 21 to enclose a chamber for placing the real-life model 30 .
[0055] In a possible implementation, a jig 170 is further included, the jig 170 is connected to the second carrier 60, and the jig 170 is provided with a plurality of mounting ports 170a for mounting the vehicle-mounted camera 80. Thus, by connecting the jig 170 to the second carrier 60 and providing a plurality of mounting ports 170a on the jig 170, different numbers of cameras can be selected for testing according to test requirements.
[0056] In a possible implementation, it also includes a control computer 90 and a cantilever bracket 100, one end of the cantilever bracket 100 is connected to the side wall of the box 20, and the other end of the cantilever bracket 100 is connected to the control computer 90, so that the control computer 90 can be adjusted to be suspended on the outside of the box 20. In this way, the control computer 90 can be suspended on the side wall of the box 20 using the suspension bracket 10, without the need for an additional table, which is conducive to saving occupied space. In addition, it should be noted that the suspension bracket 10 can adopt the specific structure of the following embodiments, or it can be a component in the prior art that can realize the suspension of the control computer 90, and this is not limited.
[0057] In a possible embodiment, the cantilever bracket 100 includes a fixed base 101, a first cantilever 102, a second cantilever 103 and a connecting plate 104. The fixed base 101 is fixed to the side wall of the box body 20, one end of the first cantilever 102 is rotatably connected to the fixed base 101, the other end of the first cantilever 102 is movably connected to one end of the second cantilever 103, and the other end of the second cantilever 103 is connected to the connecting plate 104. A connecting hole for connecting to the control computer 90 is provided on the connecting plate 104, and the lower end of the connecting plate 104 is connected to an extension plate 120 for fixing the keyboard 110.
[0058] Exemplarily, the fixing seat 101 is fixed to the side wall of the bracket 10 by fasteners, and then one end of the first cantilever 102 is rotatably connected to the fixing seat 101, and then one end of the second cantilever 103 is movably connected to the end of the first cantilever 102 away from the fixing seat 101, and finally the connecting plate 104 is fixed to the end of the second cantilever 103 away from the first cantilever 102, so as to form a cantilever bracket 100 with a simple structure and convenient assembly and disassembly. It can be rotated according to different control requirements of the user to rotate the control computer 90 to a suitable position for the user to control. At the same time, an extension plate 120 is extended downward from the lower end of the connecting plate 104, so that the keyboard 110 can also be placed in the air without the user lifting the keyboard 110 for operation. It should be noted that the connection between the back of the control computer 90 and the connecting plate 104 can be fixed by screws, so that the control computer 90 can be easily removed from the suspension bracket 10 later.
[0059] In a possible implementation, in order to enable the road scene test light box device to be flexibly moved to meet the test at different positions, a moving wheel 130 is connected to the bottom of the bracket 10. It should be noted that a wheel frame can be connected to the bottom of the bracket 10 using fasteners (such as screws, etc.), and then the moving wheel 130 can be rotatably mounted on the wheel frame to achieve the connection of the moving wheel 130 to the bottom of the bracket 10. The above connection method for the moving wheel 130 is only an example and is not limited thereto.
