Endoscope stereoscopic visualization system and method by employing chromaticity forming method

Abstract

The invention discloses an endoscope stereoscopic visualization system and method by employing a chromaticity forming method. An image conversion device is connected between a single-lens endoscope and a stereoscopic display. The chromaticity forming method is adopted by the image conversion device, so that the image conversion device can calculate to obtain deep information through the chromaticity forming method according to a plane image obtained by the single-lens endoscope, and further a deep map is generated. A demanded stereoscopic image is generated by the plane image and the deep map, and the demanded stereoscopic image is output to an external stereoscopic display, so that a user can watch the stereoscopic image conveniently. An existing single-lens endoscope is unnecessarily replaced by a double-camera endoscope system, a hardware structure of the existing single-lens endoscope is unnecessarily modified, and the problems that the existing single-lens endoscope cannot provide the stereoscopic image and a double-camera endoscope device is expensive are solved.

Description

technical field [0001] The invention relates to a stereoscopic visualization system for an endoscope, in particular to a stereoscopic visualization system for an endoscope which uses a chroma forming method to generate a stereoscopic image. Background technique [0002] The minimally invasive surgery of existing medical behaviors has become an indispensable part of the treatment of many diseases. The minimally invasive surgery is performed through endoscopic assisted surgical instruments, so that it has smaller incisions and reduces tissue trauma, and can shorten the length of time. Patient recovery period and reduced overall treatment costs. However, most existing applications in minimally invasive surgery use single-lens endoscopes, which can only display plane (2D) images. Since plane images lack depth information, surgeons can Accurately moving surgical instruments into the correct position within the patient's body can be a challenge. Surgeons usually need to rely on ...

Problems solved by technology

[0003] As mentioned above, the existing single-lens endoscope can only display a plane image, which lacks depth information and is difficult to locate accurately. Although the dual-camera endoscope has the advantage of obtaining a three-dimensional image, its It is expensive and not easy to popularize. Therefore, the main purpose of the present invention is to provide an endoscope stereoscopic visualization system and method using the chroma shaping method, which mainly uses the chroma shaping method to generate the depth The map is combined with two-dimensional images to generate a three-dimensional image. It does not need to install dual cameras and does not need to modify the hardware structure of the existing single-lens endoscope, which solves the problem that the existing single-lens endoscope cannot provide stereoscopic images and the dual-camera endoscope equipment is expensive.
