摘要：A 10:" cost multispectral digital frame camera sensor is being developed for airborne remotesens~n9' ph?t?grammetry and close-range applications. It consists of a 1320 x 1035 pixel blacka~d wh~te d~g~t~l frame camera, a 1Smm focal length lens (view angle ±16.7° x ±13.2°), a rotatingf~lter w~eel wh~ch houses user selectable narrowband interference filters, a high speed shutter,and a re~nforced PC computer with a 1280 x 1024 frame grabber, a high capacity buffer and a largehar~ drive. With this configuration, the ground pixel size is between 14cm and Sm for a range ofalt~tudes of 300m to 11,000m. Image acquisition is controlled in-flight using customizedsoftware. Several sets of multispectral imagery can be acquired quickly and held in the bufferbefore reading ~hem to the hard drive or to low cost tape media. Digital frame camera technologyh~s the potent~al to replace photography, line scanners and videography in many applicationse~ther because of its low cost or its superior imaging capabilities. This sensor has thus farbeen applied in monochrome mode for determination of x,y,z positional accuracy using analyticalphotogrammetric techniques. Results have shown that coordinates within an urban scene can bedetermined to accuracies approximately equal to the ground pixel size. Further study is under wayto develop large scale digital elevation models using these methods. Multispectral imaging willcommence in the summer of 1992 for assessment of vegetation damage associated with acid-mineleachate as well as other natural resources applications
