Problems solved by technology

However, this technology is still aimed at the identification of stationary objects in the environment. Although the object information in the environment can be continuously updated with the help of the buffer zone, it does not achieve continuity for the detection of moving objects, and because the buffer zone is required, the algorithm It is more complicated and cannot meet real-time performance, which is a great deficiency for moving object detection

Embodiment Construction

[0024] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the described embodiment.

[0025] Such as figure 1 As shown, in this embodiment, the device is composed of a black-and-white camera mounted on the head of a blind person (ie, a moving object information reading unit), a moving object detection unit, and a sound conversion output unit, wherein: the moving object detection unit, the sound conversion The functions of the output unit are realized by the DSP platform. In addition, there are peripherals headsets.

[0026] The moving object information reading unit reads in the moving object information, uses the black and white camera to pick up im...

Abstract

The invention relates to a blind guiding method based on tracking moving objects and a device thereof, and belongs to the technical field of aids for disabled persons. A moving object information read-in unit is responsible for picking images within visual field and transferring the image information to a moving object detection unit, the moving object tracks and processes the image information, and then detects the moving direction and the speed of the moving object, finally, the sound with the moving object motion information is output from an earphone to a blind person by a sound conversion output unit. The blind guiding method and the device thereof are mainly used for aiding the blind persons to acquire the moving object information in the surrounding environment and converting the moving object information into specific sound, and the blind persons judge such situations of the located environments as the vehicles passing by in front, pedestrians and the like by the sound with the moving object information.

Description

technical field [0001] The invention relates to a blind-guiding device and method in the technical field of detection, in particular to a blind-guiding method and device based on moving object tracking. Background technique [0002] Nearly 80% of human beings rely on vision to obtain information from the outside world, and the other 20% rely on hearing and touch. But for the blind, due to the loss of their visual senses, their access to external information is greatly limited. In order to improve the quality of life of the blind and minimize the pain caused by blindness, scientists consider replacing vision with hearing, hoping to pass some important visual information to the blind through this sense of substitution, especially information about moving objects. [0003] Because blind people lose the most important information input channel - vision, their perception of moving objects will be greatly reduced, such as cars speeding on the road. To solve this problem, it is n...
