Problems solved by technology

The basic assumption of the pattern recognition method is that the myoelectric signals of the same action are similar for many times or days. The pre-training model is invalid, and amputee patients need to be retrained continuously, which increases the training burden of amputee patients

Abstract

The invention discloses a prosthesis control method with multi-sensor fusion, relates to the field of prosthesis technology, and comprises the following steps: a first sensor collects the myoelectric signal of an amputee's forearm muscle when it voluntarily contracts; the first sensor detects a second The information of the sensor determines the wrist direction of the prosthetic hand of the amputee; after the wrist of the prosthetic hand is adjusted to a posture suitable for grasping, the camera is triggered by muscle contraction, and the camera captures the grasped object The third sensor determines the grasping mode of the prosthetic hand according to the grasped object captured by the camera device, and controls the grasping mode of the prosthetic hand to grasp the object through the muscle contraction ratio of the amputee; Grip strength; the amputee can let go of the grasped object through muscle contraction. This method can enable amputee patients to control the prosthetic hand autonomously, with more natural operation, no need for training process, more friendly experience and more convenient use.

Description

technical field [0001] The invention relates to the technical field of artificial limbs, in particular to a multi-sensor fusion artificial limb control method. Background technique [0002] According to the total population of my country in the sixth national census, the proportion of disabled persons in the total population of the country and the proportion of various types of disabled persons in the total number of disabled persons in the second national sample survey of disabled persons, the total number of disabled persons in my country at the end of 2010 is calculated. The number is 85.02 million, of which 24.72 million are physically disabled. Compared with the 24.12 million people with physical disabilities estimated by the National Bureau of Statistics in 2006, there are 600,000 new people with physical disabilities. For people with physical disabilities, it is of great social significance to wear functional prostheses to restore their motor ability and confidence in...
