A 3D laparoscopic video processing method

Abstract

The invention discloses a 3D peritoneoscope video processing method. According to the method, at first, two image sensors respectively collect light signals, the light signals are converted into electrical signals, and the electrical signals are converted into digital signals after modification of AD conversion, a compensation algorithm and an error detection algorithm; then, image preprocessing of data synchronous processing and data correction processing and the like are carried out on the digital signals; after image caches are processed, color space shifting processing, color look-up table processing, space matching processing and other kinds of image postprocessing are further carried out, and after 3D format data conversion processing is carried out, 3D format image data are displayed. According to the 3D peritoneoscope video processing method, 720p high-definition imaging under a 3D mode can be achieved; on the basis of image preprocessing and image postprocessing which are achieved by means of an FPGA, matching processing between original image data time and space can be effectively achieved, and stability and adjustability for images are guaranteed; image cache processing can cache image data on a large scale, and instantaneity is guaranteed.

Description

technical field [0001] The invention relates to a video processing method, in particular to a 3D laparoscopic video processing method. Background technique [0002] Compared with traditional two-dimensional imaging, three-dimensional imaging can display depth information, so it can better understand the shape and motion state of things in all directions. The success of the movie "Avatar" is the introduction of 3D imaging technology into the film and television industry for the first time. The introduction of three-dimensional imaging technology into the laparoscopic imaging system can enable doctors to obtain clear and three-dimensional real visual images, greatly improving the efficiency and success rate of laparoscopic surgery. [0003] The latest 3D laparoscopy system abroad not only realizes 3D imaging, but also has an image resolution of more than one million pixels, which is 720p or even 1080i high-definition imaging. [0004] Due to the failure to master the key hig...

Problems solved by technology

[0004] Due to the failure to master the key high-resolution micro-image sensor and its 3D imaging technology, coupled with insufficient research and development investment, my country's research and development and application in the field of high-end 3D laparoscopy, especially the development of new products using the latest technology, has not yet been reported.
