曝光调整方法、装置、计算机设备和存储介质
摘要：
本申请涉及一种曝光调整方法、装置、计算机设备和存储介质。所述方法包括：获取平面扫描图像；根据所述平面扫描图像，计算每个像素点的三维信息；根据所述平面扫描图像、每个像素点的三维信息、相机坐标系与投影机坐标系的变换关系以及标准光场，得到曝光补偿参数；根据所述曝光补偿参数进行曝光调整。能够根据当前扫描的物体的表面颜色以及材质的变化，实时调整曝光参数，提高采集到的图片的信噪比。进一步的提升重建三维图像的质量。
摘要（英）：

The invention relates to an exposure adjustment method and device, computer equipment and a storage medium. The method comprises the steps of acquiring a flat scanning image; computing three-dimensional information of each pixel point according to the flat scanning image; acquiring an exposure compensation parameter according to the flat scanning image, the three-dimensional information of each pixel point, a conversion relation between a camera coordinate and a projector coordinate and a standard light field; and performing exposure adjustment according to the exposure compensation parameter.The exposure parameter can be adjusted in real time according to the surface color and material change of a currently scanned object, and the signal to noise ratio of the collected picture is improved. The quality of the reconstructed three-dimensional image is further enhanced.
