Abstract: A digital image detecting system that employs a touch-sensitive monitor as operating center is stated here. With touch-screen and easy-to-use measuring software, its efficiency has been greatly improved compared to the traditional manual image instrument. Its basic structure and measuring principle are presented first, and then the software’s interface and the calibration method, and finally the fundamental principle of the two key algorithms for image detecting: sampling and marking.

Abstract: According to serious accident of general overturn and machine damage that happens while an enterprise steel wharf’s port fixed crane with a rated capacity of 10 t was hoisting load. Checking the safety device and safety structure of key part of the accident crane, and the adaptability of maximum amplitude rated capacity and other cause of the accident, finally put forward safety measure of integrated management of cranes.
