激光测距仪是一种简单的技术，用于通过计算投影在被测物体表面上的激光点（或激光线）的变形来获得三维信息。我们已经提出了一种适用于镜面物体的激光测距仪，它由激光投影仪、透镜、半透半反镜和两个图像传感器组成。结果表明，测距仪的精度是敏感的这些部件的失调，然而，传统的摄像机标定方法不能纠正这种测距仪的失调。针对这一问题，提出了一种基于遗传算法的激光测距机标定方法。
Laser rangefinder is a simple technique used to obtain three-dimensional information by calculating the deformation of a laser point (or a laser line) projected on the surface of a measured object. We already proposed a laser rangefinder applicable to specular object, which consist of laser projector, lens, half-mirror, and two image sensors. It is shown that the accuracy of the rangefinder is sensitive to misalignment of these parts, however, conventional camera calibration methods cannot correct the misalignment of this rangefinder. To overcome this problem, we proposed a novel laser rangefinder calibration method by using of Genetic Algorithm (GA).
