Abstract: A low-vision reading vision assisting system based on OCR and TTS, having an image acquisition module, a processing module and an output module. The image acquisition module is used for scanning a read object and acquiring and outputting an image. The processing module has an OCR unit and a TTS engine unit. The OCR unit is connected with the image acquisition module and used for receiving the image and performing image pre-processing and single-character recognition on the image to obtain a text file corresponding to the image. The TTS engine unit is connected with the OCR unit and used for converting the text file into an audio file; and the output module is connected with the processing module and used for synchronously outputting the text file and the audio file. The system has the advantages of convenience in use and relief in eye fatigue.
