Description

technical field [0001] The invention relates to the technical field of test and evaluation of weather simulation equipment, in particular to a method and device for testing and evaluation of weather simulation equipment for field testing of automatic driving. Background technique [0002] With the development of intelligent technology in various industries, more and more intelligent systems are being applied to engineering technology, many of which may need to work in harsh weather environments, such as self-driving cars that need to operate in rainy and snowy weather During normal driving, relevant tests are usually carried out under artificial simulation conditions generated by weather simulation equipment. [0003] However, there are many differences between the weather generated by weather simulation equipment and the real weather. At present, the methods for evaluating the fidelity of weather simulation equipment are directly evaluated from the perspective of basic weat...

However, this evaluation method does not consider the direct impact of the coupling effect of weather parameters on the intelligent system. For example, under the same rainfall intensity and raindrop diameter, whether the rain generated by the rainfall simulation device and the rain in the real environment have the same interference effect on the sensor , so there is an urgent need for an objective test and evaluation method to evaluate
