Embodiment Construction

[0015] This patent implements automated metamorphosis testing of autonomous driving systems through test case generation technology and metamorphosis testing. )Wait.

[0016] 1. Prepare data. The project first needs to obtain the raw data collected by the self-driving car, unify the specifications of the raw data, and configure them into image data with consistent pixel sizes.

[0017] 2. Design the corresponding metamorphosis rules, and generate new test cases according to the metamorphosis rules and original image data. Here we choose the rule-based image augmentation technique and the generative alignment network technique as the corresponding transformation rules. In terms of augmentation rules, we consider cropping, translating, changing brightness, adding noise, rotating angles, and mirroring to process data. For Generative Adversarial Network technology, we consider generating human error-prone scenarios, such as: bad weather conditions, test cases under bad line-of-...

Abstract

The invention discloses a metamorphic test method for an automatic driving system, which is characterized in that test cases are expanded on the basis of existing automatic driving system test cases according to metamorphic rules, newly generated test cases and original data are input into an automatic driving system together, and the performance of the automatic driving system is observed, so that the problem of insufficient test is solved. Three parts ofa metamorphic test case generation module, an automatic verification module and a test report generation module are included. The input is the original test picture and the test case which is expandedbased on the metamorphic rule, the original test picture and the test case are sequentially sent to the automatic driving system, the difference of output results is compared, and possible defects of the system are judged. The method has the beneficial effects that the problems of insufficient test cases of the automatic driving system and difficulty in test predication collection are solved, meanwhile, the test loss can be reduced, and the product research and development period is shortened.

Description

technical field [0001] The invention belongs to the field of automatic driving software testing, and in particular relates to the definition of automatic driving test criteria. According to the metamorphosis rules, the test cases are augmented based on the existing automatic driving system test cases, and then the newly generated test cases are input into the automatic driving system together with the original data, and the performance of the automatic driving system is observed to solve the problem of insufficient testing. Background technique [0002] A traditional car tests its performance, but a self-driving car will have other dimensions, because it is an intelligent body similar to a person. In self-driving cars, we call it the autonomy of driving, that is, the driving ability of the vehicle itself under certain external conditions or environments. Therefore, automatic driving system testing is an important part of ensuring the safety of autonomous driving vehicles. ...
