摘要： A method for a six degree of freedom position and orientation determination of a known shape in a scenery is disclosed. The method includes taking a range image with a range imaging camera and a visual picture with a digital camera. The range imaging camera includes a sensor array with a first number of pixels. Determining a 3D cluster of points from range information collected from the sensor array to a point of the scenery. The digital camera comprises an image sensor having a second number of pixels, resulting in a 2D picture. A stored 3D digital representation of the known shape may be fitted in a virtual space to match the reproduction of the known object in the 2D picture and the 3D cluster of points and determining the six degree of freedom position and orientation of the known shape according to the virtual match.

摘要： A system is disclosed that comprises a camera module and a control and evaluation unit. The camera module is designed to be attached to the surveying pole and comprises at least one camera for capturing images. The control and evaluation unit has stored a program with program code so as to control and execute a functionality in which a series of images of the surrounding is captured with the at least one camera; a SLAM-evaluation with a defined algorithm using the series of images is performed, wherein a reference point field is built up and poses for the captured images are determined; and, based on the determined poses, a point cloud comprising 3D-positions of points of the surrounding can be computed by forward intersection using the series of images, particularly by using dense matching algorithm.

摘要： A volume determining method for an object on a construction site is disclosed. The method may include moving a mobile camera along a path around the object while orienting the camera repeatedly onto the object. The method may include capturing a series of images of the object from different points on the path and with different orientations with the camera, the series being represented by an image data set; performing a structure from motion evaluation with a defined algorithm using the series of images and generating a spatial representation; scaling the spatial representation with help of given information about a known absolute reference regarding scale; defining a ground surface for the object and applying it onto the spatial representation; and calculating and outputting the absolute volume of the object based on the scaled spatial representation and the defined ground surface.
