A package measuring apparatus includes a depth sensor, the package having a rectangular parallelepiped shape and placed on a mounting table, and at least one processor. The processor obtains spatial coordinates of four vertices within a space in which the center of the depth sensor is set as the point of origin based on data of a distance from the depth sensor to each of the four vertices and data of a position of each sensor element of the depth sensor corresponding to each of the four vertices. The processor calculates, based on the spatial coordinates of the four vertices, a length of each of three sides defined between a first vertex and three other vertices.

Method and apparatus embodiments can generate a volume fluorescence image of a tooth. Method and apparatus embodiments can project structured light patterns onto a tooth and generate a contour (volume) image of the tooth surface from acquired corresponding structured light projection images; then acquire one or more fluorescence images of the tooth generated under blue-UV illumination. A composite image that shows fluorescence image content mapped to the generated contour image can be transmitted, stored, modified and/or displayed.

The present invention provides an automatic container loading and unloading apparatus and method. The apparatus comprises: a data acquisition module, used for scanning a container truck panel to obtain laser point cloud data; a data preprocessing module, used for segmenting a laser point cloud on a surface of the container truck panel from the laser point cloud data; a key point extraction module, used for performing edge extraction on the laser point cloud on the surface of the container truck panel to obtain discrete points on edges of the keel of the container truck panel; and a straight line fitting module, used for performing random sample consensus straight line fitting on the discrete points on the edges of the keel of the container truck panel to obtain spatial straight lines of the edges of the keel of the truck panel.

An embodiment includes identifying a tree type of vegetation depicted in an image. The embodiment segments that portion of the image using edge-detection processing resulting in a contour line that defines a tree perimeter. The embodiment detects that the tree is within a buffer distance from a power line. The embodiment determines the tree's species by comparing the contour line to candidate contour lines of different tree species and calculates a diameter of the tree's crown using the contour line. The embodiment estimates the tree's height using the species and the diameter of the crown. The embodiment calculates a risk value for the tree based on a risk of contact between the power line and the tree and issues a work order to maintain the tree to prevent contact with the power line.

According to one embodiment, a reading system includes an extractor, a generator, a corrector, and a reader. The extractor extracts a first candidate region from an input image. The first candidate region is of a candidate of a region in which a meter is imaged. The generator generates a rectangle around the first candidate region when an exterior form of the first candidate region is circular. The rectangle corresponds to the exterior form of the first candidate region. The corrector generates a second candidate region by using the generated rectangle to correct the exterior form of the first candidate region to approach a perfect circle. The reader reads, from the second candidate region, a numerical value indicated by the meter.

A file generating device (100) extracts, when a captured image captured by an image capturing device is acquired, based on the acquired captured image, a shape of an object included in the captured image and generates, based on the extracted shape, text information that includes a drawing indication of the shape. The information processing apparatus (200) refers to a storage unit that stores therein, regarding each of a plurality of objects, identification information on the objects in association with the text information that includes a drawing indication of the objects and acquires identification information on an object, from among the plurality of objects, that is associated with the text information in which similarity to the generated text information satisfies a criterion.
