Based　on　the　intelligent　AC　contactor　control　system　and　the　auxiliary　plane　mirror　imaging　system,　a　special　dynamic　process　of　intelligent　AC　contactor　testing　method　is　proposed　by　collecting　sequence　images　of　the　dynamic　process　of　AC　contactors　with　a　monocular　high-speed　camera.　By　detecting　and　identifying　feature　points　on　moving　targets　of　AC　contactors　from　the　image　sequence,　and　dynamically　tracking　feature　point　position　changes,　the　action　mechanism　with　dynamic　process　of　intelligent　AC　contactors　is　comprehensively　tested　and　analyzed.　The　measuring　technique　and　the　analysis　method　have　far-reaching　significance　for　intelligent　control　and　prototype　optimization　design　of　AC　contactors.　©　2014　Chin.　Soc.　for　Elec.　Eng.
