Photographic survey, photo-straightening
DigiCad 3D is an excellent tool for dealing with images, drawings, photographs of building, regular or irregular surfaces and maps. It operates either directly on raster images or by digitization. It is used in photogrammetry, cartography and, increasingly in recent years, in architectural photogrammetry, for which it offers powerful, easy-to-use and exclusive instruments.
Based on four or five fixed points of reference, you can operate directly on the image or on elements drawn on the image.
In the first instance, you obtain a new image without perspective distortion and to scale. In the second case, if the original image is digitized, the Dynamic Attach feature allows you to view both the digitized drawing and the straightened drawing on screen at the same time. So you have total control and increased flexibility – you can check the accuracy of your data as you work.
