Beijing Geo-Vision Tech.Co.,Ltd.
Beijing Geo-Vision Technology Company Limited, established in March, 1989, is a high-tech and software company registered in Beijing Haidian District. The registered capital is 12 million yuan. It is a joint-stock company affiliated with the State Bureau of Surveying and Mapping of China. The products can be applied in mapping and surveying, water conservancy, electricity, roads, railways, forestry, petroleum, coal, geology, urban planning and design, transportation, colleges and universities, etc.
With the combination of the operating experience of the
production, JX4G is a set of semi-automatic digital photogrammetric
workstation. This system is mainly used for the production of various scales
Digital Elevation Model, Digital Orthophoto Map, and Digital Line Graph. It has
great human-computer interaction and strong product quality control.
SSW Vehicle-Borne Mobile Modeling and Surveying System
is developed by Capital Normal University and Beijing Geo-Vision Tech. Co.,
Ltd. It includes 360 degree laser scanner, IMU and GPS, CCD camera, turntable,
This system adopts the laser scanner with long range,
high accuracy, large FOV, IMU with high accuracy. Compared with the similar
products, the advantages of SSW are as following: short initial time span, easy
operation procedure, high accuracy, automatic classification and modeling.
An SWDC is based on 4 top-grade commercial non-metric
digital cameras which are firstly reinforced and calibrated accurately, and
assembled on a mount base, together with a professional dual-frequency GPS
receiver, and a monitoring computer, etc. for automatic exposure management. In
addition, a series of software are equipped for post-processing, including
aerial photography planning, GPS calculation, and radiometric and geometric
processing of imagery. The key techniques of SWDC are virtual central
perspective image generation which combines 4 real central perspective images
into virtual one.
The SWDC is remarkably featured of flexible focal
length choice, a large field of view (able to get big B/H ratio images for
better elevation accuracy), and 4 built-ins (i.e.,internal simplified
platform,internal professional GPS, internal automatic exposure, and internal
power supply). It is applicable for a variety of scale mapping, ortho-image
production. In 2007, a pilot project of aerial phtotogrammetric experiment with
sparse ground control points and a cadastration project achieving 4-cm
precision of boundary points were implemented successfully with SWDC, which
opens new application of SWDC.
Sw3DGIS is a set of professional 3D geographic
information system used to display and analyze survey data. Based on the
advanced graphic technique, modern survey skills and advanced software
engineering, it provides a user-friendly interface and application platform in
construction of digital city, military training, emergency command, geology,
water conservancy, atmosphere, ocean, and visual tourism, etc.
