Abstract

The invention relates to a real-time image stitching method based on a circular tube operation robot. The method comprises the following steps that: mapping matrix model library stitching: carrying out projection transformation on an image collected by the circular tube operation robot at different gestures, and calculating and recording a stitched mapping matrix corresponding to each gesture according to a projection transformation result to obtain a stitched mapping matrix model library; and real-time image stitching: identifying a linear angle corresponding to a to-be-stitched image which is collected at present, and selecting a corresponding stitched mapping matrix in the stitched mapping matrix model library to realize the real-time stitching of the image. Compared with the prior art, the method has the advantages of high stitching efficiency, good stitching effect, high practical performance and the like.

Description

Technical field [0001] The invention relates to the field of image acquisition, and in particular to a real-time image splicing method based on a circular tube working robot. Background technique [0002] The round pipe robot is a machine, electricity, and instrument that can automatically walk along the outside of the pipe, carry one or more sensors and operating machinery, and perform a series of pipe operations under the remote operation of the staff or the automatic control of the computer. 化系统. The circular tube operation robot often needs to collect and stitch the surrounding environment images during the operation. At present, the robot panoramic navigation mainly adopts the reflective panoramic splicing system and the feature-based panoramic splicing system. For the reflective panoramic system, the camera system requires a higher installation position, while for the pipeline motion robot, the height is a factor that affects its movement flexibility, so the reflective pano...
