Problems solved by technology
However, most of the current images are captured by a single device, and the range of captured images is limited. For example, using smart glasses to capture images of the scene, the area close to the feet of the visually impaired may form a detection blind spot, resulting in the inability to accurately identify the scene. Obstacles affecting the safe travel of the visually impaired

Embodiment Construction
[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0047] The main solution of the embodiment of the present invention is to obtain a first scene image and a second scene image, the first scene image is collected by the wearable device 10, the second scene image is collected by the ground recognition device 20, and the ground Identifying that the distance between the device 20 and the ground is smaller than the distance between the wearable device 10 and the ground; constructing a scene model according to the first scene image and the second scene image; identifying walking obstacle information in the scene model; Output the prompt information of walking assistance through the walking obstacle information.
[0048] Because the prior art uses a single device to capture images, the range of the captured images is limited, resulting in the inability to accurately identif...

The invention discloses a visual aid method for traveling, the method includes acquiring a first scene image and a second scene image, the first scene image is collected by a wearable device, the second scene image is collected by a ground recognition device, The distance between the ground recognition device and the ground is smaller than the distance between the wearable device and the ground; construct a scene model according to the first scene image and the second scene image; identify walking obstacle information in the scene model; The walking obstacle information outputs walking assistance prompt information. The invention also discloses a travel visual aid device, a travel visual aid system and a readable storage medium. The invention aims at accurately and comprehensively identifying the scene situation where the visually impaired people are located, and improving the travel safety of the visually impaired people.
Description
technical field [0001] The invention relates to the technical field of obstacle avoidance, in particular to a travel visual aid method, a travel visual aid device, a travel visual aid system and a readable storage medium. Background technique [0002] With the continuous development of society, people pay more and more attention to the visually impaired. As an obstacle avoidance device that facilitates the travel of the visually impaired, it has been more and more widely used. [0003] In the current obstacle avoidance equipment, the image of the scene is captured by the camera, and the captured image is analyzed to identify the scene where the visually impaired people are located, so as to send corresponding prompt information to remind the visually impaired people. However, most of the current images are captured by a single device, and the range of captured images is limited. For example, using smart glasses to capture images of the scene, the area close to the feet of t...
