In order to facilitate image data for further use in surveying, inspection, construction and manufacturing, software is being developed that extracts contours from image material and allows them to be exported to DXF format. The focus of the project is on the fast, easy and accurate extraction of contours from imagery of different devices. For this purpose, filters and algorithms have been preset which can be fine-tuned for different applications. Furthermore, the calibration of different cameras and recording devices is possible. Distortions caused by lenses are thus removed from the image material. The storage of a ratio (e.g. mm/pixel) enables the true-to-scale export into the DXF format. The software enables enormous time savings when generating DXF data from ordinary image material. More information about ContourTrace can be found here: ContourTrace 2019.
