A Study on the Moving Distance and Velocity Measurement of 2-D Moving Object Using a Microcomputer

마이크로 컴퓨터를 이용한 2차원 이동물체의 이동거리와 속도측정에 관한 연구

In this paper, the moving distance and velocity of a single moving object are measured by sampling three frames in a two-dimensional line sequence image. The brightness of each frame is analyzed, and the bit data of their pixel are rearranged so that the difference image may be extracted. The parameters for recognition of the object are the gray level of the object, the number of vertex points and the distance between the vertex points. The moving distance obtained from the coordinate which is constructed by the bit processing of the data in the memory map of a microcomputer, and the moving velocity is obtained from the moving distance and the time interval between the first and second sampled frames.
