STEREOCARTO has three RMK Top 15 de Zeiss analog photogrammetric cameras with focal distances of 150 mm and 300 mm; and a photograph format of 23 cm x 23 cm. They are still used for specific projects combined with modern technologies, such as inertial GPS systems.
A photogrammetric digital camera is an instrument that allows, through an electronic image sensor (a set of CCD's), to obtain metric digital images directly.STEREOCARTO has the technical means to capture and process photogrammetric data.
In particular STEREOCARTO has these large-format digital cameras:
- Leica ADS40 SH52 Sensor
- DMC Intergraph
STEREOCARTO has a Leica terrestrial scanner. Its main product of this technology is an accurate point cloud which can be exported into different formats such as those of Autocad (2D and 3D), Microstation (2D and 3D), PACE, PDMS, PDS, etc.
Images taken with the terrestrial photogrammetric camera can be oriented in the same way than images from aerial cameras. This is an efficient technique to obtain two and three-dimensional terrain representations. The main applications can be found in the urban sector, specially in facades, bridges and monuments surveying.
