Abstract

The embodiment of the invention discloses a camera fault injection method and device, and the method comprises the steps of obtaining a camera video signal, carrying out the fault simulation processing of the camera video signal according to a received fault injection instruction, obtaining a fault simulation signal, and outputting the fault simulation signal to a to-be-tested controller. According to the camera fault injection method and device, based on normal camera video signals, by performing fault simulation processing on the camera video signal according to a predetermined signal faulttype; and then inputting the video signal subjected to fault simulation processing into the to-be-tested controller, the processing and injection of camera signal faults are realized, more comprehensive detection of the to-be-tested controller is facilitated, and the stability and reliability of each function of the to-be-tested controller are ensured.

Description

technical field [0001] The present invention relates to the technical field of simulation, and more specifically relates to a camera fault injection method and device. Background technique [0002] In recent years, with the advancement of automotive electronics technology and people's emphasis on traffic safety, more and more ADAS-related controllers are deployed in mass-produced models, which is of great significance for improving driving safety and reducing traffic accident rates. For the development of vehicle electronic systems, a controller needs a large number of tests before it is officially installed to ensure the stability and reliability of the functions of the controller. [0003] As an important environmental perception sensor, the camera is widely used in ADAS controllers due to its advantages of low cost, wide detection range, and little influence from weather factors. The current solution for camera fault injection in ADAS testing is mainly to use general fau...
