An imaging system includes an imaging device configured to image an imaging subject on an imaging optical axis, and a calculation unit configured to acquire data relating to a position and/or a size of the imaging subject based on image information acquired by the imaging device through the imaging. The calculation unit acquires change information relating to condition change in the imaging and/or change in the imaging subject on the image. The change is caused by interposition of a light transmitting member when the light transmitting member is interposed on the imaging optical axis during the imaging, and the calculation unit corrects the data based on the change information.

In an aspect, a method for imaging a target comprises steps of: performing optical coherence tomography (OCT) scanning on the target with one or more beams of source light, the one or more beams of source light comprising a plurality of wavelengths; wherein performing OCT scanning comprises: providing the source light to a reference optical path and to a sample optical path, wherein providing the source light to a sample optical path comprises illuminating the target with the source light; and recording interference data corresponding to an interaction of a light from the reference optical path and a light from the sample optical path; processing the interference data; and identifying blood or one or more blood-features in the target based on an optical attenuation of light in or associated with the sample optical path by the blood or the one or more blood-features.

A package measuring apparatus includes a control unit and a depth sensor that picks up a package having a rectangular parallelepiped shape placed on a mounting table from substantially directly above the package. The control unit is configured to: specify data of the package in an acquired depth image data by comparing with background depth image data; calculate a height of the package and specify positions of three vertices located on a leftmost, rightmost, and uppermost or lowermost side in the depth image data; obtain two-dimensional coordinates of the three vertices based on a view angle of the depth sensor, data of a distance from the depth sensor corresponding to the three vertices, data of a position of each sensor element, and the number of sensor elements; and calculate a length of two sides defined between a third vertex and other two vertices based on the two-dimensional coordinates.

Disclosed herein is a dimensioner table (DT) that is highly transportable and can be removably or permanently affixed to a mobile platform (MP). This allows freight to be scanned at the time of pickup or each time it is unloaded/loaded onto a new MP. The dimensioning information collected from the DT can be used to create a 3D model of the freight which can be used to help provide loading instructions. The successive scans of the freight by each DT can also be used to identify any discrepancies in the 3D models or captured images which may indicate damage or partial loss of freight.
