If you use calibrated cameras, the point accuracies will be 2-4 times better. This makes the camera calibration much more stable and the accuracy much better. Nevertheless, if possible, only a few different non calibrated cameras should be used for one object. Theoretically you could take each image with a different camera and lens and each image is calibrated during orientation. Up to 1000 images per hour are oriented on current computers. Very fast, fully automatic orientation with simultaneous simultaneous calibration of any number of cameras. If you have even larger convergence angles between 2 images, or if you have an extremely poor image quality, you can also orient the images manually to the photo block, here convergence angles between 2 images of up to 170° are possible without problems. This will give you much more reserve if the pictures are not taken well enough: The automatic image orientation works even in cases that used to be only manually orientable. Up to 30° convergence angle (shooting angle) between two shots. The biggest strengths of ELCOVISION 10 are: Take photos by hand, with a tripod, aerial photos of drones or from airplanes, ELCOVISION 10 processes all images, the only condition is that you have enough image overlap and the images have a reasonably good quality.
If you are using a stereo camera such as the Leica BLK3D, you will automatically have a correctly scaled and orientated photo block. You can use any camera with normal or fisheye lenses, even mobile phone cameras can deliver good results. Photograph the object with any high-quality camera.
Now you can even model difficult cases such as interiors or cars in 3D: Even with surfaces that are almost homogeneous in color, even the smallest texture differences on the object are sufficient to produce almost noise-free 3D point clouds. Now ELCOVISION 10 shows another innovation: The fully automatic generation of high density point clouds from images in almost laser scan quality. Since its market launch in 1986 as the world's first 3D photogrammetry system for PCs, ELCOVISION 10 has presented many groundbreaking innovations in the automatic 3D evaluation of images, such as in 2005 as the first 3D photogrammetry system with fully automatic image orientation for freehand images. Generate from images of normal cameras or drones fully automatically high-precision and highly detailed 3D models and point clouds in almost laser scan quality.
