Abstract
The invention relates to a device comprising an alidade rotatably mounted on a base about a vertical axis and to which are attached an electronic distance meter having a horizontal axis and arranged to generate a point cloud, and at least one camera oriented towards an optical system housed in the alidade. Each camera is positioned so that the virtual image of its image nodal point is at the intersection of the vertical and optical axes, and is attached to a platform rotatably mounted about an axis colinear with the vertical axis and passing through the image nodal point. In the scanning mode, each platform rotates at an angular velocity opposite to that of the alidade over a plurality of angular ranges to allow each camera to capture images for colorizing the point cloud.
