Digital photogrammetry
(A) the basic functions of digital photogrammetry system
Most digital photogrammetry systems should have the following basic functions: ① image digitization; ② image preprocessing; ③ coordinate measurement; ④ Image positioning; ⑤ Automatic aerial triangulation; ⑥ forming a nuclear image; ⑦ Image matching; ⑧ Establish a digital terrain model and edit it; Pet-name ruby automatic contour drawing; The attending doctor makes orthophoto images.
(2) Introduce the commonly used digital photogrammetry system.
The task of digital photogrammetry system is to complete photogrammetry based on digital images or digitized images. Here are two typical domestic digital photogrammetry systems.
1.VirtuoZo digital photogrammetry system
The digital photogrammetry workstation VirtuoZo was developed by Academician Zhang Zuxun of Wuhan University. It is a modern photogrammetry system with complete functions and a high degree of automation, which can complete the mapping and production of 4D products from automatic aerial triangulation (AAT) to various scales. VirtuoZo uses the most advanced fast matching algorithm to determine the same name points, and the matching speed is as high as 500 ~ 1 000 points /s, which can process aerial images, SPOT images, IKONOS images and close-range images. It can not only make all kinds of surveying and mapping products of various scales, but also be the most powerful operating platform integrating GPS, RS, GIS, 3D landscape, urban modeling and GIS spatial data collection.
2.JX-4C digital photogrammetry system
JX-4 C is a semi-automatic microcomputer digital photogrammetry system developed by Academician Liu Xianlin of China Academy of Surveying and Mapping. This system is mainly used to produce DEM, DOM and DLG of various scales. It is a digital photogrammetry system with strong practicability, good man-machine interaction function and strong product quality control.
