Problems solved by technology

In this way, when the infrared positioning tracker is used, in addition to the spot pattern of the infrared marking target, there are noises in the image of the infrared camera
The existence of this image noise will interfere with the discrimination of the infrared marker target coordinates by the surgical navigation system and affect the accuracy of the operation.

Abstract

The embodiment of the invention is suitable for the technical field of image processing, and provides an image denoising method and device for an infrared camera and computer equipment, and the method comprises the steps: controlling the infrared camera to carry out the image collection of a circular infrared reflection identification target, and obtaining an infrared image which comprises a plurality of pixel points, each pixel point has a corresponding pixel value; according to the pixel value of each pixel point, carrying out gray scale binarization processing on the infrared image; identifying a light spot connected domain in the infrared image after gray binarization processing, and detecting the shape of the light spot connected domain; and denoising the infrared image based on the shape of the light spot connected domain. By adopting the method, the interference of other factors on the detection of the infrared identification target can be eliminated, and the detection accuracy is improved.

Description

technical field [0001] The embodiments of the present application belong to the technical field of image processing, and in particular relate to an image denoising method, device and computer equipment for an infrared camera. Background technique [0002] With the rapid development of medicine and computer science, computer-assisted surgery has become a hot spot in the research and application of modern surgery, and has been widely valued by people. Surgical navigation system is an important application direction of computer-assisted surgery. It can help doctors choose the best surgical path, reduce surgical damage, and improve the accuracy, convenience and success rate of surgery. At present, the most commonly used surgical navigation system is to use infrared positioning tracker to track and locate surgical instruments and infrared targets on lesions in real time, calculate the working position, direction and movement path of surgical instruments, and based on this Preope...
