1.....BECAUSE OF INDISPENSABILITY, ESPECIALLY IN “NON-CONTACT” MEASURING AND PHOTOREALISTIC 3D-MODELING OF EXISTING SPATIAL STRUCTURES (AS WELL AS INSTALLATION AND EQUIPMENT) THAT ARE HARDLY ACCESSIBLE/COMPLETELY INACCESSIBLE OR ACCESS IS VERY RISKY OR WHEN THEIR RELEVANT DOCUMENTATION DOES NOT EXIST/IS NOT AVAILABLE.

 

2.....BECAUSE OF IMPORTANT ADVANTAGES, RELATED TO:

​

     - Different Camera-types Support: It is  possible to process images acquired from analog/digital cameras and video cameras – amateur (non-               metric) and metric ones. It is not a problem to use different types of cameras in the same project. For more information, please click  here.

 
     - Concrete Shooting Parameters Detection:  It is possible to achieve accurate  identification of the focal length of any type of cameras used,                 principal points of its optical systems, as well as aspect ratio (pixel squarness) and lens distortion levels/values. With regard to that,                           external/3rd party rendering programs can professionally render digital 3D-Models (generated in the such way) - by using perspective                         parameters which are the same as real ones related to cameras that took the shots.

     - Simultaneous Multi-image Handling: It  is possible to manipulate with many images in the same project simultaneously as well as to add new             ones at any time.

     - Single-Image-Processing Possibility: It is possible to perform full perspective restitution procedure having single image only – based on usage           of few necessary additional information.

     - Perspective-Matching Possibility: It is possible to match images of the same spatial structure - by identifying real positions of the camera used           as well as its shooting directions/angles, even if there were no apparent perspective distortions present on those matching images. 

     - 3D-Mesh Contour-Defining and Export Possibility:  It is possible to define and export generated mesh contour-data for its analysis and for use           in mapping or other relevant applications.

     - Different Types of Import-files Upholding: It is possible to process various types of 2D and 3D input data sets – saved in many specific import -           file formats. For more information, please click  here. 

     - Different Types of Export-files Upholding:  Output 2D and 3D data sets can be exported in many specific export-file formats. For more                          information, please click here.  

     - Different Image bit-depth-Types Support: There are  supported images in many bit-depths – 1-bit/Black&White images, 4-bit/Color images,

       8-bit/Monochrome images, 8-bit/“Color with Palette“ images and 24-bit/Full RGB Color images. Cocrete image bit-type usage depends on                 applied image-processing.

​

3.....BECAUSE OF SIGNIFICANT CHARACTERISTICS OF GENERATED  3D-MODELS:

​

     - They are superiorly photo-texturized and photo-colorized – so that they are almost comparable to their originals.

     - They are defined as precise CAD-like 3D-wireframes or 3D-point meshes (in the forms of sets of 3D-points alone or CAD-like triangulated                 ones).

     - They are accurate: the achieved accuracy obtained for distances between two measured control points lies in the range of 1:1700 (for 35mm             small format "amateur" camera without lens distortion compensation) - to 1:8000 (for a “Wild P32” metric camera):

​

                                  - They are accurate even when their originals are unstable during shooting.

                                  - They are accurate even when their originals are very small.

                                  - They are accurate even when their originals are very large, and

                                  - They are accurate even when their originals have been shot at large distances (as long as there are visible textures present                                         on the analog/digital images). 

​

In addition to all mentioned above,  offered services also characterize:

​

     - Low-cost and low-weight equipment (mainly, only high-quality cameras mounted on tripod are needed),

     - Ultimate equipment mobility (mainly, only what travels around the field is the low-weight camera; shots are to be processed later on at the                 office),

     - Fast in-field processing (contrary  to long-lasting overall and precise project workflow preplanning,  time for camera set-up and for shooting are         insignificantly short),

     - High versatility of the offered service applications (a lot of requirements in different professional fields are successfully satisfied),

     - Wide range of acceptable shooting distances (as long as there are textures/patterns visible/detectable on shots),

     - High accuracy/resolution presented on generated perspective restitution products (measures, 3D-models, maps, etc.), and

     - Multi-camera support (by using mutually synchronized cameras to simultaneously capture  moving and shape-changing objects).
