The invention provides a position identification method, which comprises the steps: obtaining a to-be-recognized target image through a position recognition device; predicting the target image to predict a target feasible region in the target image and a first distance transformation diagram corresponding to the target image; and according to the target feasible region and the first distance transformation diagram, recognizing the relative position between the target person wearing the position identification device and the target feasible region. According to the invention, the first distance transformation diagram represents the predicted distance between each target pixel point in the target image and the feasible region boundary, so that the position relationship between the visually impaired person and the target feasible region can be accurately recognized based on the first distance transformation diagram and the target feasible region so as to effectively guarantee safe walking of the visually impaired person. The invention further provides a position recognition device and equipment and a computer readable storage medium.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular to a location identification method, device, equipment and computer-readable storage medium. Background technique [0002] People with visual impairment, due to the lack of effective perception of the external environment, cannot know the area that can be driven, thus affecting their quality of life and range of activities. For a long time, manufacturers at home and abroad have provided various types of walking aids and equipment for people with visual impairments, trying to help them enhance their environmental perception and improve their quality of life. In recent years, with the development of miniaturized wearable electronic devices and the rapid development of image acquisition, processing and analysis algorithms, mobility aids for people with visual impairments with real-time calculations continue to emerge, providing better products and services. [0003] Ta...
