摘要

In this work, conducted by three partners (UFAM/CETELI, ICTS and ENVISION/TPV), we propose an automated dead/bright pixel distance measurement system for use on monitors and TVs screen. The proposed system use Homography transformation and proportion estimation and some simple detection algorithms to detect edge, corners, and contour. As result, the proposed system perform the 700 Euclidean distance in millimeters. As result, the average distance measurement error was 0.44 millimeter.
