Abstract

The invention is applicable to the technical field of image processing, and provides a lesion position relative positioning method and device, terminal equipment and a computer readable storage medium, and the method comprises the steps: obtaining a wireless capsule endoscope picture sequence of an organ; partitioning each frame of wireless capsule endoscope picture by using a superpixel algorithm; detecting each block in each frame of wireless capsule endoscope picture, and identifying a road sign feature block in each frame of wireless capsule endoscope picture; matching the road sign characteristic blocks of all two adjacent frames of wireless capsule endoscope pictures in the wireless capsule endoscope picture sequence; numbering all road sign characteristic blocks in the wireless capsule endoscope picture sequence according to a matching result; and obtaining the distance between the lesion position in the organ and the entrance of the organ according to the numbers of all the road sign characteristic blocks and the length of the organ. According to the invention, the lesion position in the organ can be relatively positioned, and the determination of the lesion position is facilitated.

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...
