Abstract
The procedure of object motion states estimation is developed in the paper. For moving objects with simple geometry, the information about motion states can be obtained via the implementation of object state estimator module. Using industrial CCD camera, the sampled images of the specified viewing area in the scene are analysed and the information about objects is extracted. First, paper review on machine vision, object contour tracking and recognition, related study about machine vision application in industrial automation is shown. Basic image processing method, calibration, the framework of object state estimation and procedure are explained later. In the topic of system configuration, the block diagram of whole system, the estimation of field of view of CCD and the transformation between image coordinate system and machine coordinate system are shown. Finally, the accuracy and viability of the module are verified experimentally.
