Problems solved by technology
[0004] One way is to use a blind stick. The blind stick is used as an auxiliary tool. The detection method is manual reciprocating point-by-point scanning, but the spatial information obtained by using the blind stick is limited, for example, high obstacles (such as tree branches) , small obstacles (such as wires) and other areas that cannot be swept in time and moving objects, the obstacles cannot be accurately determined;
[0005] There is also a way to use guide dogs, but guide dogs can only remember a few fixed lines, and the range of activities of the visually impaired is limited. At the same time, due to the high cost of training and maintenance, this method is difficult to popularize
[0006] Therefore, the current obstacle avoidance method has the defects of low accuracy and limited range of motion.

The present invention relates to the field of information processing technology, and proposes a method and device for playing audio information to a target object. In this solution, an environmental area in a preset direction and a preset distance from the target object is determined, and then the environmental area is determined For the envelope surface of the target object, the envelope surface refers to the surface composed of points whose distance to the target object is the minimum and / or maximum value in some or all sub-areas of the environment area, and the envelope surface includes The audio information corresponding to the point is played to the target object, so that the target object can determine where there are obstacles in the environment area based on the audio information heard, and then avoid obstacles. Areas, and obstacles in areas that the target object has not been to before are determined. Therefore, the defects of low accuracy and limited range of activities in the prior art can be resolved.
Description
technical field [0001] The invention relates to the technical field of information processing, in particular to a method and device for playing audio information to a target object. Background technique [0002] According to the data of the Second National Sample Survey on Disabilities, the number of visually disabled people in China is about 12.33 million, and about 450,000 people are blind every year. The visually impaired (including the blind) have limited mobility due to limited visual senses, which brings great troubles to life. [0003] At present, the following methods are mainly used to solve the inconvenience caused by the limited visual senses of the visually impaired: [0004] One way is to use a blind stick. The blind stick is used as an auxiliary tool. The detection method is manual reciprocating point-by-point scanning, but the spatial information obtained by using the blind stick is limited, for example, high obstacles (such as tree branches) , small obstacl...
