摘要
计算机能模拟人眼视觉环境来甄别、测量视野中的事物,随着精度的不断提高,计算机视觉能代替人眼实现简单、重复的人工操作。计算机视觉结合原木剖料可以提高原木的出材率,减少木材损耗。凭借计算机的高效性、准确性,计算机视觉能实现原木的最大利用,最大程度减少生成方木浪费的原料,提高原木出材率。将所提算法应用于自动化带锯原木切割系统的基本流程是通过图像预处理来消除图像噪声,通过颜色分割去除背景,通过边缘检测给出感兴趣区域的轮廓,应用形态学运算连接和填补被误处理的轮廓边缘,计算最大面积的拟合椭圆。实验结果表明,该算法可以满足实际生产的需要,实验精度达到95%以上。
The computer can simulate the human visual environment to identify and measure things in the field of vision.With the increase of accuracy,computer vision can replace the function of human’s eyes to achieve simple and repetitive manual operations.The introduction of computer vision into logs can increase the yield of logs,reduce wood loss,maxmize the utilization rate of logs with high-efficiency and accurate performance of the computer,minimize the production of raw materials that generate square waste,and increase the output rate of logs.This algorithm is applied to automated band saw log cutting systems.The basic process includes eliminating image noise through image preproces-sing,removing the background through color segmentation,giving the contour of the region of interest by edge detection,filling the misprocessed contour edges through morphological operations,and calculating the largest area of the fitted ellipse.The experimental results show that the arithmetic can meet the requests of actual production,and the accuracy reaches 95%.
