中文摘要：由于激光3D投影系统的光路复杂，且受空间目标的形状和大小的影响，导致在特定空间内难以取得理想的投影效果，使得投影目标与实际投影点之间存在较大的偏差，因此，提出一种辐射照度校准方法。分别利用矩形、圆形两种不同形状的辐射面和敏感面搭建辐射照度测量仪，得到4种不同辐射照度测量结果;利用斯忒藩-玻尔兹曼全辐射定律，对测量结果校准，进而完成对智能激光3D投影空间目标辐射照度的校准。实验结果表明，所提方法辐射照度校准结果与实际结果基本一致，且辐射照度校准误差保持在6W。m2以内。

外文摘要：Due to the complexity of the optical path of the laser 3D projection system and the influence of the shape and size of spatial targets,it is difficult to achieve ideal projection effects in a specific space,resulting in a sig-nificant deviation between the projection target and the actual projection point.Therefore,a radiometric illumination calibration method is proposed.Using two different shapes of radiation surfaces and sensitive surfaces,rectangular and circular,respectively,to construct radiation irradiance measurement instruments and obtain four different radiation ir-radiance measurement results;Using the Stefan Boltzmann total radiation law,calibrate the measurement results,and then complete the calibration of the irradiance of intelligent laser 3D projection space targets.The experimental results show that the radiometric calibration results of the proposed method are basically consistent with the actual results,and the radiometric calibration error remains within 6 W·m2.
