摘要

在总结摄像机标定方法的基础上，提出了一种基于标定对象的直接几何解(DGS)方法。要求在测量区域内的特定位置设置若干等高的信标。仔细调整摄像机，确保测量平面与摄像机成像平面正交。利用针孔成像模型和标定目标坐标建立测量区域点坐标计算的DGS模型。在MATLAB中利用DGS模型对测量误差引起的综合误差进行了仿真，并进行了实际测量实验。实验数据分别采用DGS模型和DLT(直接线性变换)模型进行处理。结果表明，DGS的精度和误差稳定性都明显优于DLT。本实验DGS的平均相对误差为0.5%。DGS模型比DLT模型更适合定位偏远大面积的冲击点。

Vision measurement method for impact point in large planar region

On the basis of summarizing the methods of camera calibration, a new method of direct geometric solution (DGS) based on calibration objects is proposed. It is required to establish some beacons in particular position with equal height in measurement area. Adjust camera carefully to ensure that the measurement plane is orthogonal to the image plane of the camera. The DGS model which is used to calculate the coordinates of points in measurement area is built with the pinhole imaging model and the coordinates of calibration objects. The comprehensive error caused by measurement error was simulated in MATLAB with DGS model, and the experiment of actual measurement was done. The experiment data was processed respectively by the DGS model and the DLT (direct linear transformation) model. The results show obviously that both the accuracy and error stability of DGS are better than ones of DLT. The average relative error of DGS in this experiment is 0.5%. The DGS model is better than the DLT model in locating the impact point in remote large area.
