The present invention provides a method for building an image reading model based on a capsule endoscope, a device and a medium. The method includes: driving the capsule endoscope to move within a working area, sequentially recording position coordinates and field of view orientations of the capsule endoscope when it reaches each positioning point at a predetermined first frequency, and driving the capsule endoscope to sequentially capture and record images at a predetermined second frequency; constructing a 3D model corresponding to the outer contour of the working area based on the recorded position coordinates of the capsule endoscope at each positioning point; and mapping the recorded images onto the 3D model to create an image reading model. By mapping the obtained images onto a 3D model of the working area, to enhance the visualization effect of the examination, facilitate observation, save image reading time, and increase the detection efficiency.

A capsule endoscope image recognition method based on deep learning, and a device and a medium is provided. After a plurality of frames of continuously captured images are processed to form an image sequence of a specific format, multi-channel recognition is performed on the plurality of frames of images by means of a 3D convolutional neural network model, and a recognition result is then output in combination with a recognition probability of each channel, such that the image recognition precision is improved.

A mechanical limiting mechanism comprises a swivel base, a spring arm, a loading part and a reinforcing arm. The spring arm, the swivel base, the reinforcing arm and the loading part constitute a four-bar mechanism, the loading part moves up and down through the rotation of the spring arm, and a limiting is realized through a contact of the spring arm and the reinforcing arm. When the spring arm and the reinforcing arm drive the loading part to move downwards, after the spring arm is abutted against the reinforcing arm, the four-bar linkage mechanism cannot rotate, a mechanical limiting is realized, and the loading part can be prevented from falling. There is no need to add additional parts, and different height changes of the limiting are realized only by adjusting the size of the spring arm and/or the size of the reinforcing arm.
