A method of predicting the gravity-free shape of a glass sheet and a method of managing the quality of a glass sheet based on the gravity-free shape of the glass sheet. The initial shape of a glass sheet is determined. When the glass sheet is flattened, values of stress at a plurality of locations in the glass sheet are obtained. A shape that the glass sheet will have when the flattened glass sheet is deformed such that the values of stress are zero is predicted as a stress-induced shape and a gravity-free shape of the glass sheet is predicted by combining the initial shape and the stress-induced shape. Quality management is performed on glass sheets based on gravity-free shapes thereof predicted using the method of predicting the gravity-free shape of a glass sheet.

An inspection system for mounting on a user's hand. The inspection system comprising: an imaging unit comprising two sub-units, the first sub-unit being configured to provide images from a first point of view and the second sub-unit being configured to provide images from a second point of view; and a measuring unit configured to provide data relating to a physical property measured at a measurement location on the user's hand. The imaging unit has a separation sensor configured to measure the separation between the two sub-units of the imaging unit. A method of inspecting and/or servicing a machine is also disclosed.

To enable both an increase in reproducibility for reproduction of a shape of an object and suppression of an increase in data amount. An information processing apparatus including: an acquisition unit that acquires first information associated with a result of estimation of a shape of an object on a real space and second information associated with a result of estimation of a geometrical feature of the object; and a correction unit that corrects the first information on the basis of the second information.

Examples of a depth estimation method include acquiring a plurality of depth maps, and outputting one output depth map obtained by compositing the plurality of depth maps with a lower average difference between distance values of adjacent pixels than in a case of directly using distance values included in the plurality of depth maps.

A measurement probe of the present disclosure that scans a surface of a measurement object to measure a three-dimensional shape or the like of the surface of the measurement object includes a first movable portion having a stylus, a second movable portion that is connected to the first movable portion to be movable in a Z direction, a third movable portion that is connected to the second movable portion to be movable in the Z direction, a first position measurer that measures a first position of the first movable portion in the Z direction, a second position measurer that measures a second position of the second movable portion in the Z direction, and a third position measurer that measures a third position of the third movable portion in the Z direction. A first relative position is calculated based on the first position and the second position. A second relative position is calculated based on the first position and the third position. The first relative position of the second movable portion with respect to the first movable portion in the Z direction and the second relative position of the third movable portion with respect to the first movable portion in the Z direction are maintained constant.
