LED Chip Electrode Positioning Based on Machine Vision

Abstract:

The paper mainly studies the automatic positioning system of LED chip electrode based on machine vision technology, The main idea is taking, analysis and processing the LED chip images through the machine vision technology, and accurately finding the LED chip electrodes and their coordinates, then sending the coordinate informations to the servo control system to achieve precise positioning the LED chip electrodes. This paper focuses on the identification and coarse positioning of the LED chip, the precise positioning of the LED chip electrodes and analysis of image matching accuracy
