Problems solved by technology
[0002] In automatic driving, it is necessary to fuse the data of the on-board sensors and control the vehicle according to the fused data. It is often impossible to overcome the shortcomings of each sensor by using the same type of sensors multiple times, and obtain the output data of different sensors. And use Combined information to perceive the surrounding environment more accurately. To ensure that the vehicle can perceive the surrounding environment more accurately and control the vehicle more accurately, the accuracy of the sensor output must first be ensured, so it is necessary to test the performance of the sensor.
Existing technologies only test the performance of a single sensor without comparison with real road condition data, and do not have good real reliability

Embodiment Construction
[0022] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0023] see figure 1 As shown, this embodiment discloses an RT-based vehicle sensor performance testing method, the steps comprising:
[0024] (S1) Set up a test car and a target car, install the sensors to be tested on the test car, install RT3000 equipment in the center of the test car and the target car, and set up RT near the test area of the test car and the target car base station. The sensors include one or more of a front-view camera, a rear-view camera, millimeter-wave radar, ultrasonic radar, and lidar.
[0025] (S2) Test the test vehicle and the target vehicle. The test includes one or more of the following test, overtaking test and parallel driving test; the purpose of setting up the base station is to help the RT3000 real-value data to be more accurate.
[0026] (S3) After the test is completed, the original data of the sensor...

The invention discloses a method for testing the performance of vehicle-mounted sensors based on RT. A test vehicle and a target vehicle are set up, sensors to be tested are installed on the test vehicle, and RT3000 equipment is installed at the center of the test vehicle and the target vehicle; Set up an RT base station near the test area of the test vehicle and the target vehicle; test the test vehicle and the target vehicle. After the test is completed, copy the original sensor data and the original data of the test vehicle RT3000 from the industrial computer of the test vehicle. Copy the original data of the target vehicle RT3000 into the computer; perform time and space synchronization processing on the sensor original data, the test vehicle RT3000 original data and the target vehicle RT3000 original data; The original data of the test vehicle RT3000 were compared to analyze the sensor performance. The test method of the present invention uses RT true value data to test the performance of the sensor, so that the test result has more real reliability.
Description
technical field [0001] The invention relates to the technical field of sensor testing, in particular to an RT-based vehicle sensor performance testing method. Background technique [0002] In autonomous driving, it is necessary to fuse the data of the on-board sensors, and control the vehicle according to the fused data. Often, the shortcomings of each sensor cannot be overcome by using the same type of sensors multiple times, and the output data of different sensors can be obtained and used. The combined information can perceive the surrounding environment more accurately. To ensure that the vehicle can perceive the surrounding environment more accurately and control the vehicle more accurately, it is first necessary to ensure the accuracy of the sensor output, so it is necessary to test the performance of the sensor. The existing technology only tests the performance of a single sensor, and does not compare with real road condition data, so it does not have good real relia...
