Abstract

The present invention provides a high-precision video measurement system of a thin tube inner wall. Specifically, the high-precision video measurement system of the thin tube inner wall includes a supporter and a platform disposed on the supporter. The platform is provided with a precision guide rail. The mobile platform is slidably mounted on the precision guide rail, and is also provided with a thin tube rotation fixture. One end of the precision guide rail is provided with an endoscope. The endoscope is connected and mounted on the platform through an endoscope holder. The edge of the platform is also provided with an operation platform. The left of the operation platform is provided with a signal display device. The present invention not only reconstructs the inner wall of the pipeline fast in three dimensions to achieve high-precision detection of defects, but also completes the cross-sectional graphic data collection of the thin tube inner wall with a curvature radius greater than 100 mm with the synergistic effect of a spatial curvature sensor. The mechanical rotating mechanism is simple, the difficulty of operation is low, and low-cost high-precision testing standards are achieved.

Description

technical field [0001] The invention relates to the field of mechanical device detection, in particular to a video high-precision measurement system for the inner wall of a thin tube and a method for using it. Background technique [0002] With the continuous development of the manufacturing industry, the application of micro-pipes is becoming more and more extensive, and the detection of defects on the inner wall of micro-pipes has attracted more and more attention. After long-term use, defects such as cracks may appear, resulting in gas and liquid leakage, damaging the entire system, causing unnecessary economic losses, and even endangering the safety of personnel. Therefore, the detection of such parts has become a very important subject. The detection technology of the inner wall of large pipes is relatively mature. The most common method is to use a CCD camera to image the inner wall of the pipe, and then properly process the image to judge the defects of the pipe. Du...
