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 in conjunction with the accompanying drawings.
[0023] see figure 1 As shown, the present embodiment discloses a method for testing vehicle sensor performance based on RT, and the steps include:
[0024] (S1) Set up a test car and a target car, install the sensors to be tested on the test car, install RT3000 equipment at 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) Carry out tests on the test vehicle and the target vehicle, including 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 true value data to be more accurate.
[0026] (S3) After the test is completed, copy out ...

The invention discloses a RT-based vehicle-mounted sensor performance test method, wherein the method comprises the steps: setting a test vehicle and a target vehicle, installing a to-be-tested sensor on the test vehicle, and installing RT3000 equipment at the central positions of the test vehicle and the target vehicle; erecting an RT base station near a test area of the test vehicle and the target vehicle; testing the test vehicle and the target vehicle; after the test is completed, copying the sensor original data and test vehicle RT3000 original data from an industrial personal computer of the test vehicle, and copying the target vehicle RT3000 original data from an industrial personal computer of the target vehicle; performing time and space synchronization processing on the sensor original data, the test vehicle RT3000 original data and the target vehicle RT3000 original data; and comparing the sensor original data subjected to time synchronization with the test vehicle RT3000 original data subjected to time synchronization and space synchronization, and further analyzing the performance of the sensor. According to the test method, the performance of the sensor is tested by adopting the RT true value data, so that the test result is more real and reliable.
