Abstract

This application is applicable to the field of image processing technology and provides a relative positioning method, device, terminal equipment and computer-readable storage medium for lesion location, including: obtaining a sequence of wireless capsule endoscope pictures of an organ; using a superpixel algorithm to Each frame of the wireless capsule endoscope picture is divided into blocks; each block in each frame of the wireless capsule endoscope picture is detected, and the road sign feature blocks in each frame of the wireless capsule endoscope picture are identified; the wireless capsule endoscope picture is The road sign feature blocks of all two adjacent frames of wireless capsule endoscope pictures in the capsule endoscope picture sequence are matched; according to the matching results, all road sign feature blocks in the wireless capsule endoscope picture sequence are numbered; according to The numbers of all landmark feature blocks and the length of the organ are used to obtain the distance between the lesion location in the organ and the entrance of the organ. Through this application, the position of the lesion in the organ can be relatively positioned, which is more conducive to determining the location of the lesion.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a relative positioning method, device, terminal equipment and computer-readable storage medium of a lesion position. Background technique [0002] Wireless capsule endoscopy has become an important technical means for the inspection of the digestive tract, especially for the inspection of the small intestine, which is an area that cannot be inspected by ordinary gastroscopes and colonoscopes. The wireless capsule endoscope is only the size of a capsule. It is equipped with a camera module, an image processing module, and a wireless transmission module. There is no pain during gastroscopy and colonoscopy. The existing wireless capsule endoscope positioning systems mainly include capsule radio signal positioning, capsule magnetic positioning and capsule visual positioning. Capsule radio signal positioning technology is to use the sensor array outsid...
