Abstract
A triangulation-based laser rangefinder is able to achieve a favorable balance between measurement accuracy and measurement time. However, conventional triangulation-based rangefinders are known to be difficult to apply to the 3-D shape measurement of specular objects with shiny surfaces. We previously 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.
