Intelligent walking stick based on grid laser omnidirectional vision

Abstract

The invention discloses an intelligent walking stick based on grid laser omnidirectional vision. The intelligent walking stick structurally comprises a base, a supporting rod, a handle, a help seeking button, a voice broadcast opening, a noctilucent ring, a glove and a temperature control button, due to the fact that the distance between a refractor and the ground is changed, the area of an obtained light source is changed, and by changing the installation mode of a mirror plate of the spherical refractor, the mirror plate is limited through the limiting mechanism, the angle of the mirror plate can be changed according to different users, the area of a light source can be obtained after the distance between the refractor and the ground is changed, the front light source can be obtained and refracted into the camera in time, and the walking stick can normally provide front road surface information for the users; when a user passes through a wet muddy ground, the friction force between the base and the muddy ground is small, the borne supporting force is reduced, and the slipping phenomenon is likely to occur, the inserting rods in the sleeve plates are inserted into the ground, the slipping phenomenon occurring when the base passes through the wet muddy ground is reduced, and safe use of personnel is facilitated.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation, and more specifically relates to an intelligent walking stick based on grid laser omnidirectional vision. Background technique [0002] The cane is a kind of medical rehabilitation aid. It is used by people with mobility issues and visual impairments. Due to the dark light at night, the user cannot obtain the road information ahead in time when walking. Four grid-structured light projectors. The projector projects the light on the ground. The refractor refracts the light on the ground to the camera. The acquired information is transmitted to the processing unit through the camera. The processing unit judges the road conditions ahead and plays it by voice The information is played at the mouth, so that the user can know the road conditions ahead in advance; in the prior art, when the cane is used for personnel rehabilitation assistance, the height of the cane changes due to the different he...

[0002] The cane is a kind of medical rehabilitation aid. It is used by people with mobility issues and visual impairments. Due to the dark light at night, the user cannot obtain the road information ahead in time when walking. Four grid-structured light projectors. The projector projects the light on the ground. The refractor refracts the light on the ground to the camera. The acquired information is transmitted to the processing unit through the camera. The processing unit judges the road conditions ahead and plays it by voice The information is played at the mouth, so that the user can know the road conditions ahead in advance; in the prior art, when the cane is used for personnel rehabilitation assistance, the height of the cane changes due to the different heights of different users, while the angle of the refractor remains unchanged for a long time , so that the distance between the refractor and the ground changes, the area of ​​the light source obtained changes, and the front light source cannot be refracted to the camera in time, which affects the cane's normal provision of road information ahead for the user.
