摘要
采用图像的边缘检测技术,设计了盲人图像感知系统,使盲人通过皮肤电刺激来感知图像信息,为盲人提供了一种获取视觉信息的新方法。该系统包括图像采集与处理系统和电触觉装置,用于产生皮肤电刺激。盲人通过摄像机采集图像,对该图像进行边缘检测得到边缘图像。然后把边缘图像发送给电触觉装置的单片机微处理器,单片机根据接收到的边缘图像数据控制二维电极阵列产生相应的电刺激,盲人通过皮肤电触觉来感知图像的边缘轮廓信息。盲人图像感知系统使盲人能够以触觉的方式"看到"视觉图像,大大提高了盲人的生活质量。
A blind image perception system is designed using image edge detection technology to make blind people sensing image information through skin electrical stimulation,provide a new method for blind people to obtain visual information.This system consists of two parts:The first part is image acquisition and processing part,which is worn on the blind person’s head;the second part is an electrical tactile device,which is worn on the abdomen of the blind for generating electrical stimulation of the skin.The blind people capture a image through the camera.The system performs edge detection on this image to obtain the edge image.This edge image is then sent to the microcontroller unit(MCU)of the electrical tactile device.The MCU controls the two-dimensional electrode array to generate corresponding electrical stimulation,according to the received edge image data,so the blind people sense the edge information of the image through electrical tactile of the skin.The blind image perception system let the blind can'see'the visual image in a tactile way,which greatly improve the quality of life of the blind man.
