Embodiment Construction
[0026]Described image acquisition module comprises at least one CCD camera, and the signal output end of each CCD camera is respectively connected with the signal input end of central processing unit, and CCD camera can directly convert image into digital signal, and the digital signal of its output comprises brightness signal, Red (R), green (G), blue (B) signals. In this embodiment, in order to achieve a better use effect, the image acquisition module uses two CCD cameras to simulate the shape, color and brightness information of objects in the surrounding environment seen by human eyes. Two CCD cameras are separated by a certain distance and set horizontally, which can simulate the angle difference when the human body's eyes see the same object, so as to form a stereoscopic visual effect. In order to make the CCD camera always keep accurate focus and record images with the highest definition during the user's movement, the present invention sets a distance measurement and s...

An electronic dot-matrix type image touch sensing device comprises an image acquisition module, a data processing module, a current generation module, and a touch generation device. The image acquisition module is used for acquiring shape, color and brightness information of surrounding objects. The data processing module is used for receiving the shape, color and brightness information of the surrounding objects which is acquired by the image acquisition module, outputting different control signals according to the information acquired by the image acquisition module so as to control the current generation module and the touch generation module to generate current stimulations in different range, strength and frequency for a human body. The current generation module is used for generating currents in different strength under control of the data processing module, and the currents simulate the human body through the touch generation device. The touch generation device is used for receiving control signals outputted from the data processing module, and the currents in different strength and generated by the current generation module are used to generate current stimulations in different range, strength and frequency for the human body. The electronic dot-matrix type image touch sensing device is capable of quickly and accurately transmitting the shape, color and brightness information of the surroundings to the blind, and accordingly life quality is improved for the blind.
Description
technical field [0001] The invention relates to a sensing device and a sensing realization method, in particular to an electronic dot-matrix intelligent blind image tactile sensing device and a sensing realization method. Background technique [0002] my country is the most populous country in the world, and it is also the country with the most blind people in the world. As a vulnerable group in society, blind people have many inconveniences in their daily life. How to enable blind people to live like normal people, perceive the rich and colorful environment around them, and obtain information about the shape, color and brightness of objects to improve the quality of life of blind people has always been a challenge. It is an important field of research. And the existing assisting tool for the blind is only applicable to the blind when they go out to act alone, so as to avoid potential safety hazards caused by no visual aid. With the development of computer vision, pattern ...
