By means of analysis of detecting methods for surface cracks of the existing slab, a detection method based on image feature to surface crack of slab was put forward. The system architecture and the specific implementation process were described. The method took network cameras and IPC as the core of the system??s hardware platform. The digital image acquired by the network camera was sent via Ethernet to IPC.A software developed in IPC by VS2008 realizes the real-time monitoring to the state of the upper surface and the side of the slab, and the video of each slab was record. The system supplemented by automatic recognition algorithm mainly artificial line marked defects detect surface defects of slab. The software in IPC can also replay the recorded slab video to re-defect defects. Phase consistency algorithm for automatic recognition algorithm is used, which has nothing to do with the brightness information of image. 相似文献

数字图像技术在棒材自动计数装置中的研究 总被引:1,自引:0,他引:1
利用数字图像处理技术[1]在棒材自动计数装置方面的研究,目前基本上是采用对捆装棒材横断面图像进行各种数学形态学方法[2]的处理,其结果在很大程度上依赖于图像本身的质量和所采取的图像处理算法。根据图像处理技术中的投影[2]原理,并结合生产特点改进设计方案,提出一种新的图像处理方法,可以大大提高棒材自动计数的准确度。 相似文献

A high-density cDNA microarray with colorimetry detection system to simultaneously monitor the expression of many genes on nylon membrane is described and characterized. To quantify the expression of genes and to isolate differentially expressed genes, the southern hybridization process on filter membranes was employed. The levels of gene expression were represented by color intensities generated by colorimetric reactions in place of hazardous radioisotopes or costly laser-induced fluorescence detection. The gene expression patterns on nylon membranes were digitized by devices such as an economical flatbed scanner or a digital camera. The quantitative information of gene expression was retrieved by image analysis software. Quantitative comparison of the northern dot-blotting method with the microarray system is described. Applications employing single-color detection as well as dual-color detection to isolate differentially expressed genes among thousands of genes are demonstrated. 相似文献

通过构建不规则三角网模型的方法,采取包围盒方法排除两三角网模型中大量无效三角形单元,辅以空间编码技术进一步定位相交三角形集合,即利用AUTOCAD软件下的VBA语言实现初期网格模型构建和最终交线生成;中期数据处理采用VC++编译环境,对其进行相交检测并求出交线端点坐标,经过端点排序最终生成连续的多段线或闭合交线环形成包络面,此举能够极大地降低计算过程的实体建模和运算的大量数据而导致的计算效率低,最终准为实现露天矿生产过程中数字化模拟. 相似文献

AbstractVarious methods of detecting surface defects are being used in automated industrial manufacturing environments. This work presents the design and development of a laser charged couple device (CCD) displacement scanning system. The surface defect detection method using a laser CCD displacement sensor is derived from an idea in which surface defects such as cracks, inclusions and holes of three‐dimensional morphology characteristics are compared to normal surface especially in continuous casting slabs. Some novel research methods have been applied to develop the surface defect detection system used: first, getting a one‐dimensional distance matrix along transverse direction and a two‐dimensional matrix combining with a certain moving speed through the laser CCD displacement sensor; second, obtaining the slab surface profile and mapping to a greyscale image and finally, obtaining the surface defect regions by an image processing and searching algorithm and quantitatively detecting slab surface defect shape and depth. The research results in the lab trials have shown that the methodology proposed is effective to detect two‐dimensional defect size and reconstruct a three‐dimensional surface defect shape. At the same time, it is also able to accurately locate and identify surface defects and realise automatic surface defect non‐destructive detection online, and provides a theoretical base and technology idea for further studying surface defects online inspection for hot continuous casting slab. 相似文献
