Embodiment Construction

[0037] The specific implementation manners of the present invention will be described in further detail below in conjunction with the drawings and embodiments.

[0038] A wheelchair control method based on head gesture recognition technology.

[0039]The first step, on the basis of existing wheelchair, add following hardware: image acquisition equipment (common CCD camera is used in this embodiment), calculation and control unit (miniature notebook computer is used in this embodiment), support and motor. The image acquisition device is fixed at a position facing the human face through one end of the bracket; the other end of the bracket is connected with the vehicle body. The image acquisition device is used to take images of the user's head; the calculation and control unit is used to save the image, detect the position information of the user's face and nose, so as to obtain the user's head posture and generate control commands; Command to drive the wheelchair to make corre...

Abstract

The invention provides a head gesture recognition technology-based wheelchair control method, and belongs to the field of artificial intelligence technology. A wheelchair body is provided with an image acquisition device, a computation and control unit, a bracket and a motor. When the wheelchair is used, the image acquisition device acquires a head image of a wheelchair user in real time and transmits the head image to the computation and control unit. The computation unit processes, analyzes and computes the image to acquire human face and nose position information and judges the head gesture of the user according to the human face and nose position information. According to the acquired head gesture, the computation and control unit generates a corresponding control command. Finally, the motor drives the wheelchair to move according to the acquired control command. Based on a non-contact image sensing and detecting method, the distribution condition of the human face gesture and the nose position in the image is comprehensively considered, so the head gesture judgment is more accurate, the control of the wheelchair is facilitated, and the method has the advantages of friendly man-machine interaction, convenient use for seriously disabled persons, and low additional cost.

Description

technical field [0001] The invention relates to a wheelchair control method based on head gesture recognition technology, which belongs to the technical field of artificial intelligence. Background technique [0002] In order to improve the self-care ability of the disabled and promote the development of social civilization, the technology of electric wheelchairs has developed rapidly in the past 20 years. However, in these electric wheelchairs, users still mainly rely on joysticks or buttons to manually control the motion of the wheelchair, and for some severely disabled persons such as quadriplegics, such wheelchairs cannot meet the requirements. [0003] In recent years, with the continuous improvement of the cost performance of computers, and the rapid development of image processing, pattern recognition, artificial intelligence and other related fields, it has become possible to develop an intelligent system that allows users to control the movement of wheelchairs throu...
