Abstract: This paper proposes a method for high-dynamic images composition based on the 3CCD multiple-channel achromatic image. The model extracts three different components of three channels in 3CCD achromatic image as the synthetic image sequences to make full use of the information of 3CCD image, and it can effectively remove parts of the high-light area and over-saturation region. It reduces the needs for synthetic image amount. Experimental results show that the method relative to the usual achromatic image has a better dynamic range and SNR.

摘要： 提出一种基于非彩色物体3CCD多通道的高动态图像的合成方法。将非彩色物体在3CCD中3个通道的3个不同分量提取作为合成的图像序列，充分利用3CCD图像的信息，可以有效地去除部分图片中的高光区域与过饱和区域，并减少需要进行合成的图像数量。实验表明该方法相对于一般的非彩色物体图像具有更好的动态范围与信噪比。
