3D photogrammetry system is to measure and calculate the physical quantity (position, size, shape, area) of the object to be written through pictures. The 3D close-up photogrammetry system can be used for various purposes, such as surface area/volume calculation, contour/cross-section measurement, and plan/3D modeling, by calculating the 3D coordinates of the object by analyzing the photographed data.

I. General civil engineering measurement and design

Calculation of soil volume for development sites or sand disaster sites, creation of contour/section maps for slope collapse sites, creation of cross-sectional maps for river sand control projects, topographic measurement/mapping - for GIS systems, sand displacement measurement, volume calculation for normal surfaces, road/building plans, etc.

1、Planning of relic sites, 3D modeling of excavated artifacts, etc.

2、Quarry site, lime, coke, rock salt, etc. measurement. 

3、Metal corrosion parts measurement.

4, building structure, three-dimensional model measurement of complete sets of equipment.

5、Plant equipment of mechanical equipment/projects, complete sets of equipment, etc. 

6, the current effect of three-dimensional mode representation.

Second, three-dimensional shadow point graphics workstation PPSG, 3DSCAN volume analysis software features

Using ordinary non-volume digital camera for shooting

The system adopts common data management mode, with image processing, data calculation and analysis

Convenient graphics editing function

Results directly and fully automatic way to generate object DOM DEM and DSM 3D models

Fully automatic internal data processing mode, no need to manually add points or find common points to intervene

Realize 3D visualization, as well as 3D model in the measurable function, and can quickly get the volume data of the measured object

Three, system components

1, camera lens aberration or out of the orientation of the elements of the determination and output tools

The tool for calculating the aberration of digital camera lens or out-of-position elements.

2、The tool for measuring and outputting the aberration of the camera lens or the outgoing orientation element

A tool for calculating the aberration of a digital camera lens or the outgoing orientation element.

3、Image tool (can be imported into the software of Southern CASS)

It is a tool to make contour lines, vertical and cross-sectional drawings, and soil volume calculation by analyzing the measured data and CAD data with the basic software tools.

4、Aerial photos and multiple camera correction tools

It is a tool to convert the simulated photos into data that can be analyzed by the basic tool of the software.

Canon EOS 6D kit (24-105mm) parameters

Canon EOS 6D SLR camera is an excellent full-frame SLR product in terms of pixels, imaging effect, HD video, LCD screen effect or performance in terms of body workmanship, drip-proof and dust-proof. If you want a full-frame DSLR with strong detail expression, a wide and bright viewfinder, good battery life, and the need for HD video capabilities, there is no doubt that the Canon EOS 6D is a good choice.

No need for a camera for measurement
We do not need an expensive camera for measurement, but a normal digital camera in the market. The customer can correct the skew of the captured image. 

No need for measuring points
If the size of the image is displayed (or if not, the distance or the distance to the subject can be taken), the 3D data with the size can be produced. There is no need for troublesome pre-measurement such as shooting position. A large number of correspondence points can be searched automatically by using the automatic correspondence point processing function.

Various methods to measure soil volume
3D shapes can be measured by the average cross-section method and triangular mesh method.

Quick and easy operation for anyone
Anyone can easily operate the camera, computer, and other general operations. No complicated technology is required, so it can be used well from the introduction date.

Convincing visual effects
The 3D simulation function is enriched by the measurement results based on the photographed images, and the visual presentation can be realized, so that even people who are not engaged in photography can make convincing data.
