The Electronic Police System is an important trend of the development of the Intelligent Traffic System present. Aim at video images taken by the Electronic Police System, a kind of vehicle detection algorithm based on detecting area is proposed. This method combines background difference with edge difference and morphological steps to detect vehicles, and the accuracy of the algorithm is further improved by correcting the frame data stream. Experimental results demonstrate that the algorithm is effective and can meet the needs of real-time requirement.
For the automobile stamping parts quality inspection problem, this paper discusses the advantages and disadvantages of the contact measurement method and non-contact measurement method. It adopts non-contact photography-type scanner to obtain stamping parts point cloud, and compares and analyzes the automobile stamping parts point cloud and digital model based on ‘Geomagic-qualify’ software. In order to obtain accurate comparison result, it adopts alignment methods like benchmark feature surface, best fit, and RPS, etc. and finds out that RPS alignment method can obtain the values that are mostly approximate to the practically measured values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
