Estimate the Size of the Moving Vehicle LWH Based on Machine Vision

Abstract

The main content of this paper is based on the estimate of LWH(length width and height) dimensions of a machine vision moving vehicle. The information of a vehicle’s length width and height is an important parameter to monitor Road. To achieve non-contact rapid detection of the parameter of a moving vehicle’s size, can effectively improve the efficiency of the road monitoring and provide effective technical means for China's road transport management department. First get the vehicle in sequences image and extract the vehicle from background. Then, we transform the two-dimensional image to three-dimensional image with a simple projection model for getting the parameters of the length, width and height of the vehicle. Experiments show that the accuracy of the test results of this algorithm is relatively high.
