Abstract

The invention provides a character image correction method. The method comprises the following steps: information is transmitted, reflection information of the transmitted information is received, scenery information in a view field is acquired, and a character image in the view field is acquired; according to the scenery information, distortion parameters of the character image are calculated; and according to the distortion parameters of the character image, distortion correction is carried out on the character image. The embodiment of the invention, on the other hand, also provides a character image correction device and a character recognition device. According to the above scheme of the invention, as information is actively transmitted during a shooting process, the reflection information is then received, and the scenery information in the view field is acquired, more information advantageous to distortion parameter estimation can be acquired based on the assistant way. When the character image is corrected, the distortion information of the character image can be dynamically acquired in real time, parameter estimation can be well completed based on the captured reflection information, the distortion parameters of the character image can be accurately calculated, and the problem of character image distortion can be better solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular, the present invention relates to a text image correction method and device. Background technique [0002] Image processing refers to the technology of analyzing images with computers to achieve the desired results, also known as image processing. Image processing generally refers to digital image processing. Digital image processing is the use of computers to process image information to meet human visual psychology or application needs. First of all, digital image processing technology can help people understand the world more objectively and accurately. The human visual system can help humans obtain more than 3 / 4 of information from the outside world, and images and graphics are the carriers of all visual information. Although the human eye is highly discerning and can recognize thousands of colors, in many cases images are blurred or even invisible to the huma...
