Endoscope smudginess detection device and smudginess detection method

Abstract

The invention relates to an endoscope smudginess detection device and a smudginess detection method. The endoscope smudginess detection device is used for being in butt joint with an endoscope and comprises a main body, the main body is fixedly provided with an RGB three-color lamp assembly, the RGB three-color lamp assembly right faces an optical filter of the endoscope, and the RGB three-color lamp assembly can emit red, green and blue monochromatic light and can be switched among the red light, the green light and the blue light. Monochromatic light emitted by the RGB three-color lamp assembly penetrates through an optical filter, is received by a sensor of the endoscope and is imaged. In addition, monochromatic light emitted by the RGB three-color lamp assembly can be switched among red light, green light and blue light, so that the color of the auxiliary light during imaging can be switched among the three colors, and images under the auxiliary light of the three colors are subjected to smudginess judgment through a host. Therefore, misjudgment of the host caused by high transmittance or reflectance of partial smudginess to the auxiliary light with a single color can be avoided.

Description

technical field [0001] The invention relates to the related field of endoscopes, in particular to an endoscope dirt detection device and a dirt detection method. Background technique [0002] The endoscope has image sensors, optical lenses, light source lighting, mechanical devices and other components. It can enter the stomach through the mouth or insert into the body through other channels, and display the internal conditions of the human body on the external screen in the form of images, so that doctors can observe and diagnose ; [0003] During the use of the endoscope, the inside and outside of the lens and the outside of the filter are prone to dirt. Among them, when there is dirt on the outside of the filter, due to the short distance between the filter and the sensor, the image will be blurred during imaging. There will be black spots or even larger black spots on the skin, which will easily affect the normal judgment of the doctor during the operation; [0004] At...

AI Technical Summary

Problems solved by technology

[0005] Based on this, it is necessary to provide an endoscope contamination detection device and a contamination detection method for the problem that different dirt on the filter of the endoscope has different transmittances to the light source, which may lead to misjudgment by the computer.
