Abstract

The invention relates to a real-time image splicing method based on a circular pipe operation robot. The method includes: a step of establishing a splicing mapping matrix model library, performing projection transformation on images collected by a circular pipe operation robot in different postures, and calculating according to the result of the projection transformation And record the splicing mapping matrix corresponding to each posture to obtain the splicing mapping matrix model library; the real-time image stitching step is to identify the straight line angle corresponding to the currently collected image to be spliced, and select the corresponding splicing mapping matrix in the splicing mapping matrix model library to realize Real-time stitching of images. Compared with the prior art, the invention has the advantages of high splicing efficiency, good splicing effect, strong practical performance and the like.

Description

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