Publication number: 20130136309Abstract: A method of determining functionality of a vision-based imaging system for a vehicle includes capturing images by the vision-based imaging system. The images include landmarks that are identified in multiple images for distinguishing displacement of landmarks between the images. Edge maps for each of the images are generated. Like regions of at least two edge maps are compared for distinguishing displacement of a landmark between the at least two edge maps. Each pixel location of a first edge map is compared with a same pixel location of a second edge map for determining whether each compared pixel location has a different intensity value. An aggregate number of pixel locations having a different intensity value between the at least two edge maps is determined and compared to a threshold. An error message is generated in response to the aggregate number being less than the threshold.Type: ApplicationFiled: November 30, 2011Publication date: May 30, 2013Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Wende Zhang, Bakhtiar Brian Litkouhi
