多源图像融合技术及其在公安刑事摄影工作中的应用

Multi-source image fusion technology and its application in criminal photography

近年来,多源图像融合技术的应用越来越多,它可以将同一场景以不同成像方式或者不同成像时间获得的不同图像融合为一幅图像。这种技术可以综合多张照片的信息量,提高视觉感知,便于进行计算机的处理,因此,可在公安刑事摄影工作中用于对疑难指纹、立体痕迹、强反光客体痕迹、高逆光现场照片等的拍摄和处理,从而最大程度的准确反映被摄景物的实际情况。

In recent years,multi-source image fusion technology has been increasingly applied,which enable us to make a series of images of the same scene with different imaging modalities or different imaging time become one picture by image fusion.This technology integrates more information from multi-source images,improves the visual perception,and makes it convenient for computer processing.Therefore,in the work of criminal photography,image fusion technology can be used for difficult fingerprints,three-dimensional marks,strong reflection object traces,high backlighting scene photographs,thus making it possible to accurately reflect the actual situation of the scene.
