The invention provides a dysphagia screening system based on computer vision, and relates to the technical field of image recognition, and the system comprises an image collection module which collects image data of a swallowing event to obtain a time sequence image sequence; the motion field establishing module is used for extracting a motion point track sequence according to the time sequence image sequence and establishing a global motion transformation field; the motion separation module is used for carrying out registration correction on the global motion transformation field and carrying out motion separation on the stabilized image sequence to obtain local deformation components; the region segmentation module is used for carrying out key region segmentation on the local deformation components to obtain swallowing function parameters; and the risk identification module is used for identifying the obstacle risk of the swallowing function parameters and generating a swallowing obstacle screening report. According to the method and the device, the technical problem of relatively poor screening accuracy of the dysphagia based on the computer vision in the prior art can be solved, and the technical effect of improving the screening accuracy of the dysphagia based on the computer vision is achieved.
