摘要
投影仪的标定是结构光三维视觉测量系统应用的基础。提出了一种利用投影二维平面靶标对投影仪进行现场标定的新方法。与传统的投影仪标定相比,该方法不需要精密的标定设备,提高了标定精度,简化了标定过程,能够满足现场不断变换的要求。实验证明:该标定方法获得的结果较准确,方法简便易行,能够满足现场不断变化的测量需求。
Projector calibration is the basis for a structure-light 3D vision measurement system. The method of the 2D projection planar target images to calibrate the projector is used. Compared with the traditional planar target in the projector calibration, this method improves calibration accuracy, simplifies the projector calibration process without any expensive calibration device. Experiments show that the calibration result is good, and the 3D measurement requirement can be met.
