Problems solved by technology

[0003] However, the depth sensor based on laser speckle coding can calculate the depth information according to the position change of the received speckle. Since the speckle is flooded by sunlight outdoors, the depth information cannot be calculated according to the change of speckle, so it is invalid outdoors.

Embodiment Construction

[0027] Such as figure 1 Said, a kind of assistive glasses for the blind, which can avoid water surface and obstacles, and realize channel detection. Including glasses body, attitude angle sensor, two linear polarizers, two infrared cameras, infrared speckle projector, two bone conduction earphones, battery and processor; two infrared cameras are respectively embedded in the frame above the left and right lenses, The polarization directions of the two linear polarizers are perpendicular to each other (one is parallel to the horizontal plane, and the other is perpendicular to the horizontal plane), and they are respectively fixed in front of the two infrared cameras; the infrared speckle projector and the attitude angle sensor are embedded in the frame, and are located Between the infrared cameras, the two bone conduction earphones are respectively arranged at the ends of the temples; the battery and the processor are embedded in the temples, and the side walls of the mirror fra...

Abstract

The invention discloses a pair of blind people assisting glasses used for keeping away from water surfaces and obstacles, which is used for guiding the blind people to walk to a passage region withoutobstacles and water surfaces. The glasses contain devices such as a red speckle projector, two infrared cameras, an attitude angle sensor, a processor and two bone conduction earphones. The glasses greatly improve the safety and convenience for the blind people to keep away from barriers and water surfaces and select the passage direction, are favorable for the blind people to keep away from regions with water surfaces and obstacles while going out to find a correct passage, and has the advantages of being good in environment adaptation, high in user compatibility, good in wearability and lowin cost, avoiding occupation of two ears of the blind people, and being applicable to a moving condition.

Description

technical field [0001] The invention relates to a pair of blind assisting glasses for avoiding water surfaces and obstacles. Background technique [0002] According to the World Health Organization, there are approximately 285 million visually impaired people in the world, of whom as many as 39 million are blind. Due to the lack of normal vision, the blind cannot effectively distinguish the terrain ahead, predict obstacles and water surfaces, and choose a passable route. Depth sensors based on laser speckle coding or binocular vision technology can obtain high-speed color data streams and depth data streams, so the application of these sensors for detection is spreading in the field of visual assistance for the blind. [0003] However, the depth sensor based on laser speckle coding can calculate the depth information according to the position change of the received speckle. Since the speckle is flooded by sunlight outdoors, the depth information cannot be calculated accordi...
