Aerial Cameras,Camera Calibration,and Aerial Photography,

摘要

The basic components of a photogrammetric mapping camera consist of the camera mount,camera body and lens cone,shutter,lens,magazine,and intervalometer/viewfinder. The characteristics of modern camera lenses are discussed,and guidelines are given for selecting the proper aerial camera to meet a specific aerial photographic task. The objectives of camera calibration are to establish the geometric and imaging characteristics of the camera system. The practical aspects of achieving these objectives are brought out in a detail discussion of the multicollimator method of calibration used by the Geological Survey. A number of photographic parameters and natural elements,besides the camera itself,that affect the recording of photographic detail are described. (Author)
