Image measurement based on machine vision is a promising method for the precise measurements of machine parts. As for a large sized work piece that exceeds the FOV (field of view) of the camera, image mosaic must be performed to acquire the panorama of the work piece. The problematic behavior of image mosaic is the contradiction between the precision of mosaic and the complex of algorithm adopted...
To solve the problem of image measurement for work piece larger than the view field of the camera, it is necessary to obtain the panorama of the object to measure. Because the template matching algorithm for image mosaic based on similarity measure will lead to long time consumption, this paper proposed an optimization method based on multi-scale and multi-resolution to speed up the shrinkage of the...
