Provided is a nonaqueous ink composition which has fine record drying characteristics when being disposed on the surface of a substrate and from which a recorded matter having excellent post-processability is obtained. The nonaqueous ink composition contains organic solvents. The organic solvents include an organic solvent (b). Organic solvent (b): At least one selected from the group consisting of alkylamide-based solvents (b1) and cyclic amide-based solvents (b2).

The image analysis apparatus comprises a posture calculation unit that calculates a plurality of posture information items respectively indicating postures of a plurality of facets constituting a surface of a three-dimensional model, the three-dimensional model being placed in a virtual space and representing a target object in a real space, a reference calculation unit that calculates reference plane information indicating a reference plane based on three or more surface location information items, the surface location information items respectively indicating locations of three or more specific spots on the three-dimensional model, and a relative posture calculation unit that calculates relative posture information items indicating postures of the facets relative to the reference plane based on the posture information items and the reference plane information.

The present disclosure provides a technique advantageous for assigning attribute information to a three-dimensional model. An information processing method for assigning attribute information to a three-dimensional model of an object, wherein a computer calculates an area size and a normal direction of each face of the three-dimensional model, determines a line-of-sight direction based on the calculated area size and normal direction, obtains an image of the three-dimensional model viewed from the line-of-sight direction, inputs the image viewed from the line-of-sight direction into a trained model that outputs attribute information from input images to obtain attribute information of the three-dimensional model, and assigns the attribute information to the three-dimensional model.

Three-dimensional data about the object is calculated based on a plurality of images obtained by shooting the object using the imaging apparatus, and positions and postures of the imaging apparatus when capturing the plurality of images are calculated. The position and posture of the imaging apparatus when shooting an area requiring inspection of the object identified are determined based on the image obtained by shooting the object and the three-dimensional data, from among the calculated positions and postures of the imaging apparatus. The target position and target posture about the mobile body including the imaging apparatus to shoot the area requiring inspection for subsequent inspection are determined using the determined position and posture of the imaging apparatus.

The image analysis apparatus comprises an image generation unit that generates a first two-dimensional image and a second two-dimensional image, and a difference calculation unit that calculates a difference between the first two-dimensional image and the second two-dimensional image. The image generation unit generates the first two-dimensional image representing a first three-dimensional model as a two-dimensional plane viewed from a first viewpoint in a first virtual space, the first three-dimensional model being generated based on a measurement result of a shape of an object at a first time in a real space. The image generation unit generates the second two-dimensional image representing a second three-dimensional model as a two-dimensional plane viewed from a second viewpoint in a second virtual space, the second three-dimensional model being generated based on a measurement result of a shape of the object at a second time in the real space. A same coordinate system is set in the first virtual space and the second virtual space. In the coordinate system, a position and a viewing direction of the second viewpoint are a same as a position and a viewing direction of the first viewpoint, respectively.
