Defects detection in web inspection based on DM642 DSP
In this paper, a novel approach for defects detection in web inspection based on TMS320DM642 DSP development board is proposed. The whole commercial web inspection system can be divided into there major function units: image capture, real-time processing of line-scanned images and the networking transmission. An innovative line-analysis based threshold detection algorithm is presented. The experimental results corroborate that this real-time method implements efficiently in the limited resources on a single DSP with high detection accuracy and robustness to the linear grayscale change. Though the analysis, we can see the total process ability of this algorithm finally achieves 22.51 M/s, which is nearly five to ten times as large as the other algorithms such as SOM based on statistics running on general processor without any obvious decline of the detection accuracy.
