| Abstract: | A robot collects environment information mainly by its vision system. In order to improve recognition accuracy and positioning precision under variable lighting conditions, this paper describes a new pattern design and proposes a method to adjust the color threshold according to the credibility of current color threshold. Image morphology is used to optimize the recognition results. The vision system is tested in the project Family Life Support Multi Robot Systems. |

| Keywords: | machine vision threshold image morphology vision system |
