A measurement method of image fusion based on multi camera was proposed to avoid reduced accuracy and measurement error caused by mage occlusion, reflection and other reasons in multi-line structured light stereovision measurement system. The measurement method can be used on the prior multi-line structured light stereo vision measurement system hardware platform by updating its software. The fusion image can be created after these processes: extracting band images, image feature matching, matching band image with the line structure light knife which create the band image by using traditional stereo vision measurement method, converting all band images to a camera's imaging plane, and realizing image fusion by resampling and interpolation of band images after coordinate transformation. Experiment proved that the method can greatly decrease reduced accuracy and measurement error caused by band image defects.
