| Popis: | In real life, the text is one of the main carrier forms of information, which carries human civilization, and spreads knowledge to people, and also promotes culture and records history; however, how to read more information in a limited time, that is, to improve reading efficiency, has become a problem to be solved by current technology. The purpose of this paper is to integrate the existing wearable device concept, combined with a wireless intelligent sensor system; design a wearable reading assistance system designed to facilitate the use of blind and partially sighted people, based on the study and comparison of existing text recognition products; improve their functions and implementation platform, combined with wireless network; and design a wearable device that can achieve foreign text recognition and reading cognitive state reading assistance thereby improving reading efficiency. This paper proposes a method to implement foreign text decoding under the embedded platform with relatively few resources and quickly completes image acquisition, binarization, and compressed storage through the bit and storage area and DMA (direct memory access) double buffering mechanism unique to the chip selected in this paper; proposes to use the connected boundary tracking algorithm to find foreign text locators, reducing a large number of floating-point operations; does not rotate the image, instead, the image is directly sampled at the current rotation angle, and then foreign text bitstream information is acquired to realize the decoding of foreign text under the embedded platform with relatively fewer resources. |
