Leica wild t3000 manual arts11/26/2022 ![]() In this paper the new active stereo vision head of the IPR is presented. The achieved precision is in the order of 2 (DOT) 10 -5. Tests with the DCS200 camera show a repeatability of 18 micrometer standard deviation on a test field 60 X 50 X 30 centimeter. It includes extensive statistical testing to assess the accuracy of the results. The 3D coordinate computation is performed by Geodelta's bundle adjustment package BINAER. A precision better than 2% of a pixel was obtained for the target location. The least squares template matching method is implemented for the target image measurement. For the identification of the targets a circular bar code is read by the image processing software. These artificial targets are designed for automatic detection in images of a complex scene. The software part of the system performs the detection, identification, and measurement of artificial targets present in digital images. The results of the radiometric and geometric calibration of the DCS200 camera show the potential of this camera for photogrammetric applications. This camera is based on a standard 35-mm camera. For the image acquisition the Kodak DCS200 digital camera is used. 0.03 mm perpendicular to the wall.Ī digital photogrammetric system for automated 3D coordinate measurement in a production environment has been developed. A spatial reconstruction of the wall shape was possible with an average standard deviation of 0.02 mm for the object coordinates in the plane of the wall, resp. In cooperation with the Institut fuer Photogrammetrie und Bildverarbeitung Technische Universitaet Braunschweig it was possible for the first time to employ five large- format Rollei LFC recording cameras synchronously for the deformation measurement. Given a required deformation resolution of at least 0.04 mm, it is therefore necessary to employ a measurement technique that accurately and rapidly ascertains the wall condition in 3-D. During the measurement phase the masonry wall deforms by up to 0.04 mm due to relaxation. Each brick is provided with two measurement points. During the loading, the 3-D deformation behavior of the wall is determined. The goal of these tests is to post-strengthen such walls in seismically endangered zones through the use of fiber-based composites. In cooperation with the firm HILTI AG in Schaan the Swiss Federal Laboratories for Materials Testing and Research (EMPA) in Dubendorf, Switzerland is carrying out tests on masonry walls. ![]()
