Abstract

In a method for optically scanning and measuring an environment, a laser scanner emits an emission light beam, receives a reception light beam reflected from an object, and determines for a multiplicity of measurement points at least the distance from the object to a center of the laser scanner, and in which at least some of the measurement points are displayed on a display device, the measurement points are assigned to pixels of a plane and their distances to the plane are assigned to respective depths, at least the pixels between the pixels which are assigned to the measurement points are filled with values in dependence on the depth, by selecting pixels, by searching for pixels which are adjacent to the selected pixels and have a smaller depth, and by filling the selected pixels depending on the values of the adjacent pixels and on their depths.
