Pressure sensing data glove and its grasping process judgment method based on machine vision

Abstract

The invention provides a pressure sensing data glove based on machine vision and a gripping process judgment method thereof. The pressure sensing data glove based on the machine vision comprises a color camera module, a worktable panel, a PC and a data glove body. The color camera module is arranged above the worktable panel and connected with the PC through a video USB transmission line. The data glove body is arranged between the color camera module and the worktable panel and connected with the PC through a high-speed USB transmission line. The pressure sensing data glove based on the machine vision more accurately conducts tracking and judgment and is low in price, convenient to carry and convenient to popularize in a user group.

Description

technical field [0001] The invention relates to mechanical electronics and information processing technology, in particular to a pressure sensing data glove based on machine vision and a method for judging the gripping process thereof. Background technique [0002] The hand is mainly responsible for fine activities and work in the motor function, and its flexibility and movement accuracy are closely related to the daily life ability, quality of life and social activities of the human body. In medical rehabilitation, stroke patients with hemiplegia have hand motor dysfunction, and Parkinson's disease patients with hand tremor and slow movement can also lead to hand motor dysfunction; in engineering, the mechanism of hand fatigue of assembly line workers As well as the detection of human adaptability to various labor loads is also crucial. [0003] For stroke and Parkinson's patients, the traditional clinical treatment and evaluation method is that therapists conduct one-on-o...

Problems solved by technology

[0004] In recent years, there have also been some patent applications for gloves capable of hand tracking, one is to rely on optical fiber or piezoelectric sensors to achieve measurement (Chinese invention patent with application number 201310149065.8 and Chinese invention patent with application number 200810222477.9), another One is to rely on the camera to capture the marking points on the glove to achieve measurement (Chinese invention patent application number 201010507844.7). Although these systems can also track hand movements, the former has locality of tactile information, and it is necessary to increase the number of sensors to improve the measurement accuracy. Accuracy, and the increase in the number of sensors will greatly increase the difficulty of manufacturing data gloves; the latter has tracking accuracy problems caused by visual and spatial information due to light and occlusion

To improve the capture accuracy, the number of cameras needs to be increased. The increase in the number of cameras makes the entire processing system more complex, the processing efficiency is low, the requirements for PC are high, the development cost is increased, and the price is expensive, so it is not suitable for promotion in the user group.
