摘　　要：为解决不规则形状物体的表面积测量问题,提出了一种基于图像处理的测量方法。对采集到的灰度图像,利用图像分割技术,将目标区域从背景中分割出来,得到目标区域图像;利用边界跟踪得到目标区域的边界点以及各边界点的跟踪方向信息,根据其跟踪方向信息判断各边界点的状态,将边界点的一半以及所有的边界内点累加求和,得到目标区域的面积。经仿真实验证明,该方法可以实现对不规则形体表面积的有效测量。In order to measure the area of irregular solid, a measurement method based on image processing is proposed. Using image segmentation technology to segment the object region from background to obtain the target area image from the grayscale acquired. Contour tracking is used to get the boundary point of the region and tracking direction of every point, according to which the boundary point＇ s state can be judged. Accumulate all the points in the region and half of the boundary points to get the region area. The simulating experiment re- sults show that this method can realize effective measurement o{ irregular solid surface area.
