AI Technical Summary

Problems solved by technology

However, due to the complexity of the surface of the tape, the tightness and miniaturization of the scale of the tape, and the high precision required for the detection of the tape, the detection of the printing quality on the surface of the tape has been stuck in the original stage.

Abstract

The invention relates to a tape measure scale on-line automatic detecting system based on image processing and a method thereof; the system forms a main framework by a CCD video camera, two light source devices (including a direct annular epi-illuminating light source and a side LED light source), a computer equipped with an image capture card, an operating platform provided with a neck and a shielding device, and an alarm bell. The method acquires production line moving tape measure surface images by using the CCD video camera, judges whether the scale, marks and figures on the surface of the tape measure are completely accurate by the computer processing, and further monitors by using the alarm bell. The utility system can automatically check the printing quality of the surface of the tape measure in real time, and has high detecting precision and good accuracy.

Description

Technical field [0001] The invention relates to an on-line automatic detection system and method for the surface scale of a measuring tape, in particular, the quality of the measuring tape is detected by acquiring the surface image of the measuring tape and performing digital image processing with high efficiency, accuracy and high degree of automation. Background technique [0002] my country is a major producer of steel tapes, with an annual output of more than 1 billion meters. The production of steel tapes uses rolling templates to continuously print lines with specified accuracy on the steel tape. Due to objective reasons such as printing equipment, how to accurately align steel tapes Printing quality inspection has become an important part of the tape measure production process. At present, the quality inspection methods adopted by our country are relatively primitive, and the quality inspection equipment is relatively rudimentary, mainly through manual sampling inspection. ...
