ELCOVISION 10 - The leading 3D photogrammetry software for fully automated 3D object reconstruction from images.

3D Reconstructions from images: Facade documentation, Bridge deformation measurement and Volume calculation

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.


Now ELCOVISION 10 shows another innovation: The fully automatic generation of high density point clouds from images in almost laser scan quality. 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 you can even model difficult cases such as interiors or cars in 3D:


Photograph the object with any high-quality camera. You can use any camera with normal or fisheye lenses, even mobile phone cameras can deliver good results. If you are using a stereo camera such as the Leica DISTO BLK3D, you will automatically have a correctly scaled photo block.
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..

The biggest strengths of ELCOVISION 10 are:

Up to 30° convergence angle (shooting angle) between two shots.

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. 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.

Very fast, fully automatic orientation with simultaneous simultaneous calibration of any number of cameras.

Up to 1000 images per hour are oriented on current computers. Theoretically you could take each image with a different camera and lens and each image is calibrated during orientation. Nevertheless, if possible, only a few different non calibrated cameras should be used for one object. This makes the camera calibration much more stable and the accuracy much better.

If you use calibrated cameras, the point accuracies will be 2-4 times better. The highest accuracies are achieved with calibrated fixed focal length lenses, at natural points ELCOVISON 10 achieves accuracies of up to 0.7*[pixel size at object]. If points are additionally signalled with ELCOVISON 10 Targets, you will achieve point accuracies of up to 0.01*[pixel size on object].

Fully automatic generation of highly detailed, almost noise-free point clouds from the images.

ELCOVISION 10 uses a new algorithm which makes it possible to calculate a 3D point from every pixel of an image. Each 3D point is the result of a so-called forward cut, so ELCOVISION 10 has very good control over this process and can generate point clouds in almost laser scan quality. Even the reconstruction of facades from aerial photographs taken almost vertically downwards is now possible even though these show the facades only in very steep view or only at the edges of the image.:

Transformation of the photo block into the desired system of coordinates

For the ready oriented photo block there are then a number of possibilities to transform it into the desired coordinate system: Whether a local coordinate system with at least one known distance, 4 or more control points, or using GPS coordinates in the images: You have full freedom.

Further Processing Options

In the orientation module itself you can now perform area calculations, volume calculations or simple distance measurements. You can create Orthophotos and you can export the point clouds in different formats.

CAD Plugins for AutoCAD and BricsCAD

If you want to further evaluate the photo block, you can do this with the CAD plugins of ELCOVISION 10, which are available for many AutoCAD and BricsCAD versions. There you can open the ELCOVISON 10 project with the help of the plugins and process it with the ELCOVISION 10 and the CAD functions.

Here you will also find numerous sample projects, in each case the pictures only so you can compute them by yourself and also completed computed projects and cloud of points.


ELCOVISION 10 Overview of Functions

Supported cameras, capture configuration

  • All currently available, commercially available digital cameras. The higher the quality of the camera/lens combination, the better the images and the better the results. Even cameras from mobile phones give quite good results
  • All types of lenses are supported: "normal" lenses, fisheye lenses and macro lenses.
  • Stereo cameras such as the Leica DISTO BLK3D: The well-known stereo base is used directly for scaling the photo block.
