摘要
An automated video monitor alignment system for transforming coordinated systems includes a camera (80) and computer (90) to capture an image of the display bezel and the image displayed on the CRT (82). Three dimensional models of the CRT tube and display bezel are used to compute and compensate for camera perspective. Camera pixel data can then be transformed to 'flat plane' coordinates. When the relative orientation of the camera and CRT are corrected, the effects of parallax can be eliminated, allowing more accurate inspection, measurement, and lower cost fixturing on the production line. Correction factors for correcting errors due to refraction can also be generated empirically in accordance with the present invention. Slope coordinate data is generated for a sample monitor for predetermined slope coordinate locations on the tube face. Correction signals can be generated from the slope coordinate data and measured tilt angles of the monitor relative to the vision system.
