A STUDY OF GATHERING THE LOG SHAPE DATA BY IMAGE PROCESSING

对利用图像处理方法采集原木形状参数的过程作了研究。以正对原木长向摄取的图像为例，对图像处理的各个步骤及采用的算法分别作了试验和比较。结果表明，原木图像处理采用如下步骤是合理的：图像抖动二元二次多项式法及双线性内插法几何校正分段线性灰度变换二值化智能高通滤波法消除噪声ＲＯＢＥＲＴ算子边缘提取坐标提取，最后的坐标即为原木形状参数。

The process of gathering the log shape data by the way of log image processing was involved in this study. The steps taken in image processing and algorithms used in each step were experimented and compared. The results indicated, it is suitable for log image processing to use the following steps, and the final coordinates are log shape parameters: Image DitheringGeometrical Correcting By Daulity Quadratic Polynomial And Double Linear InterpolationPiecewise Linear Graylevel TransformationBilevelizing Noise Eliminating By Intelligent High Pass FilterEdge Extracting By Robert OperatorCoordinate Extracting
