由于没有视觉信息，盲人在购物、阅读、找东西等方面都面临着各种困难。为此，我们研制了一种便携式的视觉障碍者听觉引导系统SoundView。该原型系统由一个小型CCD摄像机，数字信号处理单元和耳机，工作与内置的可定制的听觉编码算法。SoundView采用环境理解技术，处理来自摄像头的图像并检测带有条形码标签的物体。然后将环境中识别出的物体编码成立体声语音信号，通过耳机供盲人使用。在SoundView的帮助下，用户将能够识别感兴趣对象的类型、运动状态和位置。与其他视觉辅助技术相比，SoundView是面向对象的，具有成本低、体积小、重量轻、功耗低、易于定制等优点。
Without visual information, the blind people live in various hardships with shopping, reading, finding objects and etc. Therefore, we developed a portable auditory guide system, called SoundView, for visually impaired people. This prototype system consists of a mini-CCD camera, a digital signal processing unit and an earphone, working with built-in customizable auditory coding algorithms. Employing environment understanding techniques, SoundView processes the images from a camera and detects objects tagged with barcodes. The recognized objects in the environment are then encoded into stereo speech signals for the blind though an earphone. The user would be able to recognize the type, motion state and location of the interested objects with the help of SoundView. Compared with other visual assistant techniques, SoundView is object-oriented and has the advantages of cheap cost, smaller size, light weight, low power consumption and easy customization.
