Design and Research on Touch-Sensitive Image Measuring Instrument with High Precision
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.
