Estimation of Target's Motion Parameters Using Line-scan Camera
LI Deren · Guangdian gongcheng · 2012
Referring to the deformed scan image of the moving target obtained by a line-scan camera,a new method was proposed to estimate the motion parameters using a line-scan camera.The method,based on one-dimension imagery model of the line-scan camera,made use of the temporal and spatial relations of the key points on the target image to establish a serial of nonlinear functions related to the motion parameters,which transforms the estimation of the motion parameters into a problem of nonlinear optimization.In the analysis of the deformed license plate images of the moving vehicles,speed and direction were estimated.The experiment results show that,the method has good practicability and accuracy.
