Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] A method for judging and reminding an obstacle for guide glasses provided in this embodiment uses a guide glasses combined with dual cameras 1 and an image processing system that combines two photos of a three-dimensional space scene to create a depth map And the mobile phone 3 of audio control player; It comprises the following steps:

[0038] Step 1. The dual cameras 1 on the above-mentioned guide glasses collect scene images at the same time, such as figure 1 shown;

[0039] Step 2. The image processing system in the above-mentioned mobile phone 3 obtains the scene image in the preceding steps, and completes the scene depth calculation based on the scene image to obtain a depth map that can reflect the three-dimensional features of the scene in the field of view of the glasses; divide the above-mentioned depth map into 5 areas , that is, the...

Abstract

The invention discloses an obstacle judgment and prompting method, particularly an obstacle judgment and prompting method for a pair of blind guide glasses. After an image processing system obtains scene images, the image processing system carries out depth calculation instantly, carries out fragmentation and obstacle mark generation on a depth image and informs a user of the obstacle distributioncondition in an audio playing mode. When the user hears an audio, the user forms an obstacle distribution state in an imagined field of view on the mind of the user and walks independently accordingto the obstacle distribution state. The invention also provides the pair of blind guide glasses employing the obstacle judgment and prompting method. The pair of blind guide glasses comprises a glasses body combined with double cameras, and a mobile phone combining the image processing system which establishes the depth image through two images of a three-dimensional space scene with an audio control player. The double cameras are electrically connected with the mobile phone. The technical problem of improving the blind guide precision of the blind guide glasses is solved, and the pair of blind guide glasses has the characteristic of relatively high obstacle judgment precision.

Description

technical field [0001] The present invention relates to a method for judging and reminding an obstacle, in particular to a method for judging and reminding an obstacle for guide glasses; in addition, the present invention also provides a method for judging and reminding an obstacle. Background technique [0002] Guide glasses are a blind detection device specially used by blind people, cataract patients and other temporarily blind people. [0003] Existing guide glasses are composed of two parts, an electronic box and glasses, and two ultrasonic transducers and an earplug are housed on the glasses. Its working principle is: the ultrasonic transducer can transmit and receive the reflected ultrasonic pulse wave to the front, the controller can measure the distance according to the time difference between ultrasonic transmission and reception, and the blind can perceive the obstacles in front through the sound change of the earphone. [0004] However, in the actual use process...
