Abstract: The application of image processing technology in household electric appliances performance test can achieve clearer and more intuitive results, taking the oil smoke test of automatic cooker as an example, the composition and frame of the whole system were designed. TMS320DM6437 as the core component of data processing in the system, background difference method as the main method to extract feature targets and the system focuses on the design of feature target extraction process and related algorithms. In addition, the application of image processing technology in household electric appliances test was discussed through the analysis of the oil smoke test of automatic cooker.

Key words: Household electric appliances testing, Image processing, TMS320DM6437, Background difference, Application prospect
