Blind guiding method and device based on point cloud three-dimensional modeling and electronic equipment

Abstract

The invention discloses a blind guiding method and device based on point cloud three-dimensional modeling and electronic equipment, and the method comprises the steps: obtaining real-time weather data, and determining a blind guiding auxiliary range according to the real-time weather data; obtaining point cloud data collected by the laser scanner in the blind guiding auxiliary range, and constructing a road three-dimensional model based on the point cloud data; and according to the road three-dimensional model, determining obstacle data on the current travel route, generating reminding information based on the obstacle data, and displaying the reminding information. According to the invention, the point cloud data of the road condition is obtained through the laser scanner, so that the road three-dimensional model is constructed, and the blind can be accurately guided on the road. In addition, according to different real-time weathers, the blind guiding auxiliary range can be adjusted according to different weathers, and it is guaranteed that road blind guiding can be efficiently and accurately conducted under different weather conditions.

Description

technical field [0001] The present application relates to the technical field of intelligent blind guidance, in particular, to a blind guidance method, device and electronic equipment based on point cloud three-dimensional modeling. Background technique [0002] Visual impairment is one of the serious public health problems in our country. Visual impairment is due to various reasons that lead to low vision in both eyes and cannot be corrected or narrowed vision, which affects their daily life and social participation. Population growth and aging have led to an increase in age-related blindness. And in recent years, with the improvement of residents' living standards, great changes have taken place in the causes of visual disease. How to provide more standardized, convenient and humanized auxiliary services for visually ill patients is an important topic at present, and the guide system is one of them. an important part. [0003] Depending on the focus, blind guide systems ...

Problems solved by technology

This single sensing itself has its own defects that are difficult to perfect. When detecting the obstacle position, only the approximate direction of the obstacle can be obtained. The accuracy cannot meet the daily use, and the size, shape and edge of the obstacle itself cannot be obtained. and other information

With the continuous development of image processing technology, through the application of machine vision and image processing technology to the field of blind guide, a visual substitute system has emerged. The substitute blind guide system can judge and recognize obstacles and common road conditions, but the mainstream The technology still stays in two-dimensional space, lacking the judgment of space and distance, and in rainy days, the road condition recognition in two-dimensional space cannot effectively avoid puddles, which is prone to misjudgment
