[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.

Embodiment 1
[0029] as attached figure 1 to attach Image 6 Shown:
[0030] The present invention provides a smart cane based on grid laser omnidirectional vision, its structure includes a base 1, a support rod 2, a handle 3, a help button 4, a voice broadcast port 5, a luminous ring 6, gloves 7, and a temperature control button 8, The bottom of the support rod 2 is welded to the top center of the base 1, the bottom of the handle 3 is nested and connected to the top of the support rod 2, the help button 4 is arranged on the front of the support rod 2 near the top, and the voice broadcast The mouth 5 is located below the distress button 4, the luminous ring 6 is set on the outer wall near the bottom of the handle 3, the glove 7 is arranged on the outer wall of the handle 3, and the temperature control button 8 is movably engaged with the middle part of the right end of the handle 3.
[0031] The support rod 2 includes a rod body 21, a processing unit 22, a camera 23, a grid projector 24, ...
Embodiment 2
[0039] as attached Figure 7 to attach Figure 9 Shown:
[0040] Wherein, the base 1 includes a bracket 11, an anti-skid seat 12, and a cover plate 13. The middle part of the upper surface of the anti-skid seat 12 is respectively fixed on the bottom surface of the support 11, and the cover plate 13 is nested in the center of the inner bottom of the slide seat 12. Position, the bottom surface of the anti-skid seat 12 is provided with concave lines, which is conducive to increasing the contact area between the anti-skid seat 12 and the ground, increasing the friction between the bottom surface of the anti-skid seat 12 and the ground, reducing the phenomenon of slipping, and ensuring the safety of users. Safety.
[0041] Wherein, the cover plate 13 includes a plate frame 131, a rod opening 132, a support plate 133, a push block 134, and a rod 135. The rod opening 132 runs through between the bottom surface and the inner wall of the plate frame 131, and the support plate 133 Lo...

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.
