Abstract: The invention relates to a docking station 2 for a surface measuring apparatus 1, more particularly an optical surface measuring apparatus. The docking station has a reference measuring surface 4 which can be brought into a covered state in which it is covered from the environment of the docking station 2 and an uncovered state in which it is not covered from the environment of the docking station 2. When the surface measuring apparatus 1 is in the docking station 2 and the reference measuring surface 4 is in the uncovered state, the surface measuring apparatus 1 can perform a reference measurement of the reference measuring surface 4 and can calibrate the surface measuring apparatus 1 using the reference measurement. In contrast, when the reference measuring surface 4 is in the covered state, it is not exposed to the environment of the docking station 2 and is therefore protected from, for example, dust, light, moisture or mechanical impacts.

Abstract: The inspecting method is for a product including a transparent substrate and a part placed at a predetermined position within a front surface of the transparent substrate, and includes an imaging step and an evaluating step. The imaging step is a step of taking an image of the front surface by an imaging device with the front surface being illuminated by an illuminating device. The evaluating step is a step of evaluating a degree of matching between an image which is derived from the image (P10) taken by the imaging device and shows a position corresponding to the predetermined position and its vicinity, and a template. The template is indicative of a positional relationship between a real image and a virtual image, of the part in a case where the part is placed at the predetermined position correctly.

Abstract: Cargo objects, in a freight-related environment, are dynamically dimensioned while being held at a cargo-handling position of a vehicle. A three-dimensional model is obtained comprising points representing surfaces of the vehicle. Using the model, the position of a point of reference of a first wheel of the vehicle is obtained, as is the position of a split point relative to the position of the first wheel point of reference. A driving direction of the vehicle is obtained. A splitting plane is determined, which passes through the split point and is perpendicular to the driving direction. A three-dimensional model of the cargo is determined by subtracting, from the vehicle three-dimensional model, the points that are positioned on the side of the splitting plane opposite to the side of the splitting plane that make up the first wheel point of reference. The volume is then determined from the cargo three-dimensional model.
