Weld-ray image detection technology research
Abstract
This topic is aims at some tall and slender pipeline welded joint to carry on the welded joint flaw examination, manages the Daoist priest 5 meters, the welded joint for the straight line seam.This project main purpose establishes a welded joint flaw automatic detection system, examines flaw and automatic evaluation flaw size and position which in the welded joint exists, finally carries on the evaluation and the rating to the welded joint.Grinds according to the topic creates the request, the union fuzzy mathematics, mathematics morphology as well as the digital image processing technology, the endeavour seeks one kind of fast effective flaw real-time enhancement, the flaw extraction and the flaw division method, causes it all obtains the satisfying effect in the extraction effect and the processing speed, finally realizes this product welded joint automatic detection.
The grasping welded joint beam image characteristic and the correlation noise reduction and the enhancement technology theory and in the method foundation, understood the selected topic the application background and the technical background, understood the selected topic the significance, uses many kinds of noise reduction and the enhancement technology method carries on processing to the welded joint beam image, requests to achieve the image signal-to-noise ratio is high, the clarity is high, and analyzes the comparison effect; Completes the corresponding algorithm 。
