Autonomous operation method and device based on electric wheelchair

Abstract

The invention discloses an autonomous operation method and device based on an electric wheelchair, and the method comprises the steps: firstly moving the electric wheelchair to a position near a target carrier, and automatically determining a reference object; and after three-dimensional point cloud data and images of the reference object acquired by the point cloud data acquisition equipment and the visual sensor are processed, decision fusion is carried out to obtain spatial position attitude information of the reference object. And then the position and orientation of the electric wheelchair body required by the user to realize autonomous transfer between the electric wheelchair and the target carrier are calculated. The electric wheelchair is adjusted according to the calculation result. According to the method, a user can independently and conveniently realize autonomous transfer between the electric wheelchair and carriers such as a sofa and a bed without assistance of other people, and the electric wheelchair can also autonomously move between a standby space and a target carrier. The electric wheelchair is more user-friendly and intelligent, and the physiological and psychological comfort of the user is improved.

Description

technical field [0001] The present application relates to the technical field of electric wheelchairs, in particular to a method and device for autonomous operation of electric wheelchairs. Background technique [0002] Wheelchairs bring great convenience to people with limited mobility. The emergence of electric wheelchairs saves manpower even more. However, traditional electric wheelchairs pay more attention to a series of functional upgrades during driving, ignoring user transfer in the home environment. Function, that is, it is difficult for the user to independently and conveniently realize the autonomous transfer between the electric wheelchair and the sofa, bed and other carriers, and it still needs the assistance of others, or it will take a lot of time and physical strength, and the user is likely to feel uncomfortable during this process. Physical and psychological discomfort. [0003] In addition, after the user transfers to the carrier, the electric wheelchair c...

[0002]Wheelchairs have brought great convenience to people with limited mobility. The emergence of electric wheelchairs has saved manpower, but traditional electric wheelchairs pay more attention to driving. A series of function upgrades, ignoring the user transfer function in the home environment, that is, it is difficult for the user to independently and conveniently realize the independent transfer between the electric wheelchair and the sofa, bed and other carriers, and still needs the assistance of others, or it will cost more It takes a lot of time and physical strength, and users are prone to feel physical and psychological discomfort in the process

[0003] In addition, after the user transfers to the carrier, the electric wheelchair continues to stay next to the carrier, which may cause inconvenience to the user or others, and if the electric wheelchair does not Timely placement will take up space and block the line of sight
