Application of image processing and recognition technology on the automatic test platform of electronic products

The automatic testing platform of electronic products is a key equipment for electronic product production test automation. And the visual detection is the core technology of the testing platform. This paper mainly gathers the screen image of electronic products and analyzes the image feature, then uses the image processing functions of smoothing filtering, threshold segmentation, edge detection, seed filling, feature extraction, pattern recognition and so on to process the image and realize automatic testing of electronic products. As an innovatively application of this paper, the efficiency of the ways of detecting LCD screen miscellaneous points with seed filling, the automatic test system for electronic products with image processing, character recognition, voice detection integrated as well as the Tesseract OCR applied to screen character recognition have been notably improved. Practice has proved that this method is fast and practical in automatic testing.
