Problems solved by technology

[0004] At present, the rehabilitation status of patients mainly depends on the doctor's diagnosis, which requires patients to enter and leave the hospital many times, causing inconvenience to life; the equipment that helps patients perform rehabilitation training only has auxiliary training functions, and cannot evaluate the patient's rehabilitation process, and then feedback the recovery effect of limb function

Abstract

The invention relates to the technical field of visual perception, in particular to a limb function rehabilitation quantitative evaluation system based on visual perception. The system comprises a data acquisition module used for acquiring real-time posture data of a patient within a preset time; a gait cycle extraction module which is used for performing gait analysis according to the posture data and extracting the gait cycle of the patient; a gait similarity acquisition module which is used for acquiring action similarity and period similarity based on a similarity evaluation unit, and acquiring gait similarity according to the action similarity and the period similarity; and a rehabilitation effect evaluation module which is used for screening abnormal gait cycles according to the gait similarity, calculating adjacent similarities between the abnormal gait cycles and a plurality of corresponding adjacent standard data sequences, and selecting the maximum adjacent similarity as fault-tolerant similarity, obtaining an average gait similarity of all gait similarities within a preset time, and evaluating the rehabilitation effect of the patient according to the fault-tolerant similarity and the average gait similarity. According to the embodiment of the invention, the rehabilitation effect of the patient can be accurately evaluated.

Description

technical field [0001] The invention relates to the technical field of visual perception, in particular to a quantitative evaluation system for limb function rehabilitation based on visual perception. Background technique [0002] Movement disorder is one of the main causes of human dysfunction. More than 10 million people around the world suffer from movement disorder, such as Parkinson's disease (PD); in addition, there are many diseases that can cause movement disorders, such as cerebral infarction, cerebral Gait disturbance due to neurological disorders such as bleeding. Therefore, the analysis of limb function has an important role in treatment and rehabilitation. [0003] In practice, the inventor finds that the above-mentioned prior art has the following defects: [0004] At present, the recovery status of patients is mainly determined by doctors, which requires patients to enter and leave the hospital many times, which causes inconvenience to life; the equipment th...
