3D endoscope calibration system and method

Abstract

The invention relates to a 3D endoscope calibration system and method. The system comprises lenses, a housing and at least one electric heating piece; the lenses are arranged in the housing at intervals, every two lenses are combined into a pair, the electric heating pieces are arranged on the outer sides of the lenses, and the temperature of the electric heating pieces is raised after the electric heating pieces are energized; the electric heating pieces and the lenses are both flexible parts. After the electric heating pieces heat the lenses, the sides, with higher temperature, of the lensesare bent toward the sides with lower temperature, and images taken by any pair of lenses can form 3D images. The lenses are bent by being heated by the electric heating pieces on the outer sides of the lenses, so that the relative angle of one pair of lenses is adjusted.

Description

technical field [0001] The invention relates to a calibration system, in particular to a 3D endoscope calibration system and method. Background technique [0002] Existing electronic endoscopes usually use miniature image sensors as the original camera. Compared with fiber endoscopes, the advantages of image resolution and high definition are obvious. In recent years, with the development of miniature endoscopes Wide application and rapid development also have certain requirements for endoscopes, which must have high resolution, good calibration ability and calibration accuracy. [0003] The traditional endoscope calibration is through mechanical adjustment and auxiliary calibration with naked eye observation. The calibration accuracy is poor. Most of the endoscope calibration process is calibrated by fixing one lens and adjusting another lens instead of The two lenses are adjusted at the same time. When the traditional endoscope is calibrated, it is difficult to rotate the...

[0003] The traditional endoscope calibration is through mechanical adjustment and auxiliary calibration with naked eye observation. The calibration accuracy is poor. Most of the endoscope calibration process is calibrated by fixing one lens and adjusting another lens instead of The two lenses are adjusted at the same time. When the traditional endoscope is calibrated, it is difficult to rotate the lens and must be calibrated before the inspection. However, if there is a slight deviation of the endoscope lens after the endoscope is inserted into the human body, It is necessary to take out the endoscope again, causing the pain of the inspectors, and the practicability is not strong
