遥感图象线性影象的增强,可以提高我们对于线性体的识别能力,便于分析判读线形构造的存在,所用的方法也比较多。可以用计算机进行图象处理,但是需要有一套数字图象处理设备,目前多数单位多不具备;还可以用光学方法在光学实验室中处理,这也要有一套光学仪器,另外也可采用光栅衍射的方法增强线性影象,所需设备就简单得多。它通常是借助 The enhancement of the linear image of remote sensing images can improve our ability to recognize linear bodies and facilitate the analysis of the existence of linear structures for interpretation. There are also many methods used. You can use the computer for image processing, but the need for a digital image processing equipment, the current number of units do not have more; you can also use optical methods in optical laboratories, which also have a set of optical instruments, the other can also use grating Diffractive methods to enhance the linear image, the required equipment is much simpler. It is usually by help
