Who can introduce surveying and mapping instruments and software?

(1)JX-4C digital photogrammetry workstation

This instrument is a set of semi-automatic microcomputer digital photogrammetry workstation developed by combining the working experience of production units. This workstation is mainly used to make digital elevation model "DEM", digital orthophoto "DOM" and digital line drawing "DLG" of various scales. The system has unique hardware configuration such as 3D input card and output card with independent intellectual property rights and software configuration of 18. It is a digital photogrammetry workstation with strong practicability, good human-computer interaction function and strong product quality control.

JX-4C DPS digital photogrammetry workstation cluster has developed into a very mature product. 7-year sales breakthrough 1000 sets.

JX-4C DPS has the characteristics of high cost performance, free training, automatic software upgrade, customized functions (providing different solutions for different users) and perfect after-sales service.

(2)Imatizer 2305 image scanner

Imatizer 2305 image scanner is a professional high-precision aerial image digitizer. It is a key product of the National "863" and the National Bureau of Surveying and Mapping in the Ninth Five-Year Plan, and won the first prize of national scientific and technological progress. This product is used to scan high-precision digital black and white, color, positive and negative aerial photographic films, and is used in digital photogrammetry and other surveying and mapping fields. It uses high-grade (professional-grade) area array CCD photosensitive device, and the gray level digitization reaches the real level of 4096 (12 bits), and 12 bits are scanned and saved, and 8-bit ordinary images are adjusted and output by special post-processing software. This technology is unique in the world at present. Imatizer 2305 image scanner, as an advanced front-end equipment for photogrammetry, can meet the requirements of surveying and mapping production in all indexes and image quality. The software and most hardware of the scanner are made in China, which is convenient to maintain. At present, this product not only serves domestic surveying and mapping units, but also exports to Southeast Asian countries.

(3) Real 3D visualization hardware platform

True 3D visualization hardware platform is the output and observation part of virtual reality system, which provides true 3D visualization platform for digital city, 3D GIS, industrial simulation design, virtual planning, virtual human surgery, space virtual training, virtual teaching, virtual museum, virtual battlefield and so on. Developed by Beijing Siwei Yuan Jian Information Technology Co., Ltd., this platform is a part of the project "Key Technology Integration and Industrialization of Digital Surveying and Mapping Technology System" which won the first prize of National Science and Technology Progress in 200 1. The platform has independent intellectual property rights, and its unique rear projection structure design is unique in the industry.

This platform is a technological innovation of the traditional 2 1/2 dimension. It uses the principle of polarized light to obtain a real three-dimensional space, which can make the observer immersive, especially the use of large screen, making the viewing angle more realistic. It is an ideal display and viewing platform for three-dimensional achievements.

The platform has the following characteristics: clear and bright, rich in color and strong in three-dimensional sense; Unique rear projection structure, bright indoor observation, not affected by indoor lighting; Circularly polarized glasses are light to wear and can accommodate dozens or even hundreds of people to watch; The adjustment mechanism of the stereo projector is simple and easy to operate; A variety of configurations meet the needs of different users, and can be used as an ordinary projector when not looking at the stereo; Compatible with 3D software developed by different companies under 3D card; The price is cheap, only115 ~1/30 of imported similar products.
