Positioning controlling apparatus and method

Abstract

The invention discloses a positioning controlling apparatus which comprises a laser transmitter used for transmitting visible laser and infrared laser which are identical in light path outwards; a first camera and a second camera used for shooting an infrared image; a third camera used for shooting a colorful image; an image identifying module used for identifying an infrared laser facula satisfying a preset condition in the infrared image; a planar positioning module which is used for adopting a center of the infrared image as an original point, and obtaining a coordinate of the infrared laser facula; a space positioning module which is used for calculating a space coordinate of the infrared laser facula according to the coordinate of the infrared laser facula as well as a distance and a focal distance between the first camera and the second camera. Furthermore, the invention also provides an adopted method. According to the apparatus and the method, since visible and invisible infrared lasers are matched to be applied, a user can radiate the visible laser onto an object needing to be operated just by simple shaking of the head part, thereby realizing a positioning function, and for the user who has trouble in moving four limbs, a mechanical artificial limb is simpler to control.

Description

technical field [0001] The invention relates to a human-computer interaction and control technology, in particular to a positioning control device and method for controlling a mechanical arm. Background technique [0002] According to the statistics of the World Health Organization, the motor dysfunction group has become the largest minority group in the world, and about 10% of the world's population, or 650 million people, live with various physical disabilities. "Helping the rehabilitation of the disabled" has become one of the major livelihood issues that our government wants to solve. The research and development of prosthetics is of great significance to help disabled people with motor function loss recover or carry out normal life. Electromechanical prosthetics can be seen as a robot that is in close contact with the human body. Unlike traditional prosthetics, electromechanical prosthetics have the ability to move on their own, which is more helpful for patients to c...

Problems solved by technology

[0005] However, due to the large difference and instability of human nerve signals, it is difficult to achieve precise control actions, and long-term adaptive training is required before use

Most of the other electromechanical prosthetic control methods rely on the limbs of the disabled who can still move, and are not suitable for the disabled with severe mobility loss, and these people are precisely the people who have the greatest demand for electromechanical prostheses
