技術摘要 / Our Technology: |
本發明係一種光場相機之光度校正方法,該方法包括拍攝相片、特徵點擷取、三角分割、變形化處理、光度誤差計算及光度校正之步驟,本發明係藉由演算方法,在不需使用一校正物體的狀態下,減少光場下光度失真的現象。
A photometric calibration method includes: obtaining a target image and a reference image by a light field camera and transforming the reference image into a revised target image corresponding to the target image; calculating a photometric calibration ratio according to a function for correlating the target image and the revised target image by using a numerical algorithm; and the intensity of the target image is divided by the photometric calibration ratio to obtain a calibrated target image. A light field of a scene is formed by all of the calibrated target image so as to improve the quality of the light field.
