成捆原木检尺自动化不仅能够提高生产效率,而且是林木资源管理的需要。通过图像处理得原木检尺直径和统计根数,这是实现检尺自动化中的重要环节。由于原木生产作业现场获取的成捆原木图像背景多样,拍照时自然光照条件不一,成捆原木轮廓识别需要较多的人工交互。通过研究成捆原木端面彩色图像中原木的色彩特征,利用它滤除大量的不相关背景,留下原木色彩近似的像素点;并结合拉普拉斯滤波器,获得原木边缘,实现成捆原木轮廓的分离,从而获得原木轮廓。
成捆原木檢呎自動化不僅能夠提高生產效率,而且是林木資源管理的需要。通過圖像處理得原木檢呎直徑和統計根數,這是實現檢呎自動化中的重要環節。由于原木生產作業現場穫取的成捆原木圖像揹景多樣,拍照時自然光照條件不一,成捆原木輪廓識彆需要較多的人工交互。通過研究成捆原木耑麵綵色圖像中原木的色綵特徵,利用它濾除大量的不相關揹景,留下原木色綵近似的像素點;併結閤拉普拉斯濾波器,穫得原木邊緣,實現成捆原木輪廓的分離,從而穫得原木輪廓。

Scaling automation for bundled logs not only improves production efficiency, but also is a requirement for forest resource management. After image processing, diameter of each log and the number of logs is obtained, and this process is key point of scaling automation for bundled logs. Because the imaging environment of bundled logs is complex, much man-machine interaction is needed while using the existing methods for outline identification of bundled logs. In this paper, the color feature of logs in the image of cross section of bundled logs has been discussed, which is used to remove the irrelevant pixels in the image and obtain the pixels of logs. In the next step, Laplace filter is used to work out the edge in the image, implementing the separation of log outlines. Finally, we achieve outline identification of bundled logs.
