摘　　要：主动式线激光三角技术的三维重建广泛地应用于工业测量领域,对于图像中目标激光影像的搜索和定位尤其重要,搜寻区域的大小影响着计算效率。本文根据激光器投射模型,以投射点为基准提出一种图像中目标所在区域的自动划分方法。在每张图像中自动定位搜索区域,在保证目标完整的情况下能够有效地缩减搜索区域,提高搜索效率,同时避免常规的按行(列)搜索方法所产生的拍摄角度重叠问题。Three-dimensional reconstruction based on triangulation using active line laser is widely applied in the field of industrial measuring.It is especially important to find and locate the part of target laser in the image,and the computational efficiency has been affected by the size of the searching area.According to the projection model of laser,an automatic method of dividing the interesting area out of the image is proposed based on the projection point.The interesting area is automatically determined in each image,which can effectively reduce the search area and improve the search efficiency in the case of guaranteeing the complete of target.The method can resolve the overlapping issues caused by the shooting angle when using the conventional searching method of line-by-line(or column-bycolumn).
