摘　　要：详细介绍了应用立体视觉技术由立体像对测定林木个体分布空间格局的方法、步骤,探索了适合林业环境下的立体视觉实现的技术路线。摄像机标定采用基于非线性度量误差模型的摄像机标定方案;图像匹配采用外极线和Canny算子检测出的树干边缘约束下的人机交互式的相关匹配。最后通过实验对文中算法、策略进行了验证。结果表明,在实验条件下,应用立体视觉测定林木个体分布格局可以达到精度要求。The approach of applying stereo vision technology on measuring distribution of tree with stereo image couple was introduced in detail and the procedure of stereo vision which fit for forestry environment was explored. The camera calibration based on nonlinear error in measure model was adopted and the interactive correlation matching constrained by epipolar line and edge of tree detected by Canny operator was used.The algorithm and maneuver in this paper were illustrated.Results proved that application of stereo vision technology on measuring distribution of tree could meet precision need in experimental conditions.
