随着遥感技术的发展,多光谱摄影作为航空遥感的一种新技术,越来越受到人们的重视。它在自然资源开发利用,生态环境监测、土地利用和资源管理等方面,都起到它的特殊作用。它在森林资源调查,森林病虫害调查和自然保护区的调查规划中也具有重要意义。航空多光谱摄影与常规航空测量摄影有其相同之处,但也有其不同之点。相同之处,即摄影时运载平台都是依靠航空器(飞机),成像过程都是通过摄影镜头,借助几何光学中心
With the development of remote sensing technology, multi-spectral photography as a new technology of aviation remote sensing has drawn more and more attention. It plays a special role in the development and utilization of natural resources, ecological environment monitoring, land use and resource management. It is also of great significance in the investigation of forest resources, forest pests and diseases and the investigation of nature reserves. Aeronautical multispectral photography has some in common with conventional aerial photography, but there are also differences. The same point, that is, photography is based on the carrier platform aircraft (aircraft), the imaging process are through the camera lens, with the geometric optical center
