Research on Self positioning Technology of Elderly Power Wheelchairs Based on VLSR Method
Power wheelchairs for the elderly are an important assistive device that can assist them in their daily activities.Howev-er,due to the limitations of the physical condition and exercise ability of elderly people,they may experience getting lost or lost while using wheelchairs.Therefore,research is based on vector line segment relationship methods to achieve automatic positioning of elderly powered wheelchairs through the use of LiDAR and visual sensors.The research first focuses on self-localization and vector line seg-ment matching,and then uses VLSR to calculate the positioning information.Finally,simulation experiments are used to compare with other methods to verify the localization ability of the method.The results show that the average root mean square error of the VS-LR method is 5.13％,and the overlap rate fluctuates between 0.6 and 0.78.Within the operating range of 10 meters,the average positioning time is 5.8 seconds.This indicates that the VLSR based self-localization technology for elderly powered wheelchairs has higher positioning accuracy and robustness.
