Abstract

Electronic Rolling Shutter (ERS) was usually considered to be the shortcoming of low-cost and low-power CMOS image sensors, because ERS will cause distorted and/or blurred images when the target is moving. In this paper, we propose a new method to measure roller's velocity by using ERS's distortion as a response of moving target rather than a drawback. In the presented method, dimension expanding method is improved to generate a repeated isosceles triangle pattern as the reference object. 2D velocity is simultaneously calculated from the distorted isosceles triangle pattern. Some experimental results are given to clarify the feasibility of the proposed method.
