传统的投影仪标定方法总是假设投影仪图像上的重投影误差是独立的、同分布的,并采用与摄像机标定相同的方法。实际上,即使摄像机图像上的测量点是独立的、同分布的高斯变量,也不可能获得投影仪图像上重投影误差的统计特性,因为原始测量误差与重投影误差之间的关系是非线性的。提出了一种根据摄像机图像重投影误差估计投影仪参数的方法。该方法不需要知道投影仪图像点的统计特性,并且充分利用了摄像机图像噪声的背景知识,因为我们的代价函数不像传统方法那样考虑投影仪图像上的重投影误差。仿真和实验证明,该方法即使在真实噪声不正常的情况下,也具有较高的精度。
The traditional projector calibration always assumes that the reprojection errors on the projector image are independent and identically distributed and utilize the same method as the camera calibration. Actually, even if the measured points on the camera image are independent and identically distributed Gaussian variables, it is impossible to obtain the statistical characteristics of the reprojection errors on the projector image, because the relation between the original measurement error and the reprojection error is nonlinear. We propose a method to estimate the projector parameters according to the camera image reprojection error. It does not require us to know the statistical characteristics of the projector image point and makes full use of the background knowledge of the camera image noise, because our cost function does not concern the reprojection error on the projector image as is the case in the traditional method. The simulations and experiments affirm that this method has higher precision, even if the real noise is not normal.
