| Abstract: | The thermal grey image captured by the dynamic detection system and the principle for detecting the image edge are introduced based on the wavelet transform. The realizing method is investigated based on the wavelet transform to recognize the welding seam on the welding temperature field image. Results prove that the recognition method is better than the traditional edge detection method in the application of the welding seam. The method has a better denoising performance and can precisely recognize the welding seam. |
