针对普通彩色相机采用多次曝光获取高动态范围图像的技术,提出了一种基于相机分段色域颜色模型的高动态范围图像获取及颜色合成的理论模型和实现方法。介绍了相机分段色域颜色模型的基本结构和建立方法。用NikonD70s彩色相机和修正的sRGB标准颜色转换模型对所提出的理论和方法进行了实验验证。结果表明,所提出的方法可以在普通彩色相机上实现高动态范围彩色图像获取与图像合成,并可同时实现高动态范围图像的颜色标准化。
A new piecewise color characterization model is proposed with a camera for the high dynamic range'imaging based on multiple exposures. The principle and the construction of the piecewise color characterization model, and the im- ages capturing, the color tone mapping and the images combination are introduced. By using an RGB color camera Ni- konD7Os, the new method can obtain high dynamic range images with standard and desired color information.
