摘要：

This letter reports a novel method for light field three-dimensional measurement by using unfocused plenoptic cameras. A light field metric model, based on which nonmetric depths in the image space can be mapped to metric dimensions in the object space, was established. Furthermore, with the aid of a three-dimensional measurement system, light field metric calibration was carried out by determining light rays with spatio-angular parameters and set up the depth relationship between the object and image spaces in accordance with the light field image properties.
