摘要：

A wide image mosaic and measure algorithm of mobile mapping system (MMS) has been proposed in this paper. Through constructing the cylinderical panorama projection relationship of triple original digital measurable images (DMIs), the wide image has been mosaiced directly. The corresponding relationship between wide image and object space coordinate has been constructed by utilizing back projection relationship between wide image and original DMIs, and synchro or asynchro stereo DMI pair of the triple original DMIs. Then, the wide image object measure algorithm has been realized. The wide image experiment illustrates that, the method of utilizing cylinderical panorama projection to acquire wide image can be applied in mosaic of sequential wide images in MMS. When original DMI possesses synchro stereo DMI pair, the absolute precision of wide image measure result can be better than 1m and the relative precision of wide image measure result can be better than 0.2m. This accuracy contents with the precision requirement of real vision object measure in city environment.
