成果介绍

本发明适用于光学测量技术领域，提供了一种多方位投影的投影仪标定方法，包括：步骤S1，利用投影仪依次在标靶周围预置的N个指定方位投射预置的标定图案到标靶平面，在每个指定方位用相机采集标靶信息图；步骤S2，处理各个指定方位下采集的标靶信息图，计算得到标靶特征点的精确相位值，进而得到投影仪图像坐标系中与所述标靶特征点相对应的亚像素坐标；步骤S3，利用得到投影仪图像坐标系下的亚像素坐标和已知的标靶特征点的三维世界坐标X对所述投影仪进行标定，求得初始标定参数；步骤S4，利用光束平差法对所述初始标定参数和所述三维世界坐标X进行优化，得到最终标定参数。本发明提供的标定方法使最终的标定结果更加精确。
