Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] The present invention is used in the automatic docking mode of the bed and chair of the intelligent wheelchair bed system, which can realize a one-button berth, reduce the operation difficulty of the user, and facilitate the use of the user. In the present invention, artificial road signs are installed directly under the head of the auxiliary bed, and a camera is installed under the rear of the intelligent wheelchair. When the smart wheelchair enters the berth area, the user will issue a docking command for the bed and chair through human-computer interaction. The intelligent wheelchair searches for artificial landmarks in the camera field of view through the autonomous movement of in-situ rotation. After the artificial landmarks are searched, the visual perception system calculates the image coordinates of the artificial landmarks and transmit...

Abstract

The invention discloses an automatic bed and wheelchair butt joint method for an intelligent wheelchair and bed system. The automatic bed and wheelchair butt joint method for the intelligent wheelchair and bed system is used for controlling automatic butt joint between an intelligent wheelchair and an auxiliary bed body. The automatic bed and wheelchair butt joint method comprises the steps that a manual guidepost unit is fixed on the auxiliary bed body, and a visual perception system unit is installed behind the intelligent wheelchair; information of a manual guidepost is acquired through the visual perception system unit and transmitted to an embedded upper computer; intelligent wheelchair positioning and motion planning based on the manual guidepost are finished by the embedded upper computer so as to achieve automatic butt joint between the intelligent wheelchair and the auxiliary bed body. According to the automatic bed and wheelchair butt joint method for the intelligent wheelchair and bed system, automatic butt joint between the intelligent wheelchair and the auxiliary bed body is accomplished through automatic identification of the manual guidepost and automatic positioning and motion planning of the intelligent wheelchair, high butt joint accuracy is achieved, use difficulty of a bed and wheelchair integration system is reduced, and a user can conveniently use the bed and wheelchair integration system.

Description

technical field [0001] The invention relates to the field of visual servoing and motion control, in particular to an automatic docking method for a bed and chair of an intelligent wheelchair bed control system. Background technique [0002] With the increasingly serious problem of aging society, various types of disabled people and long-term bedridden patients exist and continue to grow in large numbers, which puts unprecedented pressure on medical and nursing work, and the problem of helping the elderly and disabled is becoming a major social problem. The intelligent wheelchair bed system based on the integrated design of the bed and chair can provide the elderly and the disabled with stronger independent living ability, reduce the work intensity of the nursing staff, improve the quality of life of the elderly and the disabled, and ensure the sustainable and stable development of society has important practical significance. [0003] A key problem in the intelligent wheelc...
