MoDiTa - Modular Digital Camera Tachymeter
The MoDiTa project aims to trigger an innovation boost for modern motorised tachymeters. The aim is to realise and verify modular digital cameras as eyepiece attachments, including testing of the complete systems in pilot applications. The aim is to find a solution that is as cross-manufacturer as possible.
Motivation
Users of modern technical systems can benefit from a modular instrument design in times of rapid technological developments. With a modular concept for the integration of digital cameras, the considerable differences in development and service life cycles for geodetic instruments, digital camera technology and availability of wireless data transmission capacity can be decoupled. For the user, a modular purchase means: moderate upgrade costs, conversion and retrofitting in a few simple steps, mixed use (with/without digital camera) possible, lower commercial risk.
Activities
The measuring system is built according to a modular concept, the individual components can be easily exchanged. For example, cameras with different spectral properties (monochromatic, colour, infrared) can be changed in a few simple steps. With regard to technical applications such as the alignment of industrial plants, the high-precision detection of small movements and vibrations, different cameras are tested for their suitability.
After a camera change, an automated self-calibration process ensures within a few minutes that the accuracy properties of even high-precision motorised tachymeters and theodolites can be fully exploited.
Results
The current state of software implementation already offers a fairly high degree of automation with near-real-time evaluation through digital image processing and best-fit algorithms. The primary targets currently used are GPS-timed LEDs, simple marks and line crosses from collimators.
