Aiming at the imbalance of brightness and color in unmanned aerial vehicle (UAV) images captured over a large area, this paper proposes a method of uniforming light and color based on camera response functions. First, referred to two images taking by digital cameras in the same static scene, a multi-parameter image brightness error function is constructed. Then by using the Levenberg-Marquardt algorithm to estimate the optimal parameters and applying the estimated parameters into DOM processing, the uniforming of light and color of DOMs will be achieved. Experiments show that compared with the adaptive template method and the Waillis-filter method, the proposed method can ensure the uniformity of brightness and color in the image mosaic process with high efficiency and quality.
