In order to facilitate image data for further use in surveying, inspection, design and manufacturing, software is being developed that extracts contours from image material and exports them to DXF format. The focus of the project is on the fast, simple and accurate extraction of contours from image recordings from a wide variety of devices. For this purpose, filters and algorithms have been preset which can be fine-tuned for a wide range of 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. Further information about ContourTrace can be found here: ContourTrace 2019.
