Head-mounted type blind guide device

Abstract

The invention is applicable to the field of blind guide devices, and provides a head-mounted type blind guide device. The head-mounted type blind guide device comprises a laser radar system which can detect the surrounding environment of a user and forms position information of a to-be-detected object, a controller which forms road condition information according to the position information of the to-be-detected object and forms a prompting control instruction according to the road condition information, a prompting device which outputs road condition prompting information according to the control instruction, and a fixing structure which can be worn on the head of the user and is used for installing the laser radar system, the controller and the prompting device. According to the blind guide device, parameters such as environment, road condition detection, detection distance, scanning range, scanning frequency, angular resolution and measurement distance precision are effectively improved through the laser radar system; the blind guide device is easy to install, high in practicability and real-time performance, good in user experience and suitable for large-scale use and popularization, can help the blind in accurate real-time navigation and obstacle avoidance and greatly improves the walking conditions and travel safety of the blind.

Description

technical field [0001] The invention belongs to the field of blind guide equipment, in particular to a head-mounted blind guide equipment. Background technique [0002] According to the survey of relevant organizations, there are currently about 10 million blind people in China, accounting for 18% of the total number of blind people in the world, and there will be a continuous increase in the future. By 2020, the number of blind people in China is estimated to reach 50 million. As a special group in society, blind people need more care and care from society so that they can live better independently. How to walk safely is the biggest problem faced by blind people in their lives. But currently the special navigation product for the blind is not very mature yet. [0003] There is a kind of blind guide helmet that is common on the market, including a helmet shell, a camera and an ultrasonic measuring instrument are installed on the outside of the helmet shell, a GPS navigatio...
