A processor detects feature lines from an image of an object and generates projection lines by projecting line segments in shape information of the object on the image. The processor generates combinations each including a feature line and a projection line and generates plural sets each including a specific number of combinations. The processor uses each set to estimate a position and an orientation of an imaging device that has captured the image, and evaluates a result of the estimation for each set. When there is a change in a relative position or orientation between the object on the image and a shape represented by the shape information, the processor repeats generation of the plural sets, estimation of the position and the orientation of the imaging device and evaluation of the estimation result. The processor determines the position and the orientation of the imaging device based on the repeated evaluation.

Image processing apparatus and image processing method

An inspection apparatus includes a memory for storing shape information including a plurality of line segments representing a shape of an object; and a processor coupled to the memory and the processor that detects a plurality of feature lines from an image of the object, generates a plurality of combinations obtained by correlating each of the plurality of line segments and each of the plurality of feature lines with each other, generates a plurality of projection lines by projecting each of the plurality of line segments onto the image, sets a threshold value with respect to an error between a position of the projection lines and a position of the feature lines of the line segments included in each of the plurality of combinations based on a statistical value of the error, and classifies the plurality of combinations using the threshold value.

Inspection apparatus, inspection method, and computer readable recording medium storing inspection program

An estimation apparatus is configured to obtain shape information containing information about multiple line segments that depict a shape of an object; detect multiple feature lines in an image of the object captured by an imaging apparatus; receive a first instruction for associating a feature line selected from the multiple feature lines with a line segment selected from the multiple line segments and a second instruction for associating two points selected in the image with two end points selected from end points of the multiple line segments; generate a first line segment connecting the two points and a second line segment connecting the two end points; and estimate a position and orientation of the imaging apparatus in three-dimensional space by using a combination of the selected feature line and the selected line segment and a combination of the first line segment and the second line segment.

Estimation apparatus, estimation method, and non-transitory computer-readable storage medium for storing estimation program

An estimation device includes a processor coupled to a memory and configured to detect a plurality of feature lines from an image of the object photographed by an imaging device, generate a plurality of sets of a predetermined number of line segments among the plurality of line segments, select a set to be processed from among the plurality of sets based on a length-first selection order in which a line segment that is longer than other line segments is preferentially selected, generate the predetermined number of combinations in which the predetermined number of line segments included in the set to be processed and the predetermined number of feature lines among the plurality of feature lines are associated with each other on a one-to-one basis, and estimate a position and a orientation of the imaging device in a three-dimensional space using the predetermined number of combinations.

Estimation device, estimation method and storage medium

An image processing method includes acquiring a three-dimensional model obtained by modeling a plurality of objects included in a work space, acquiring, from a camera which is hold by a user, an image captured by the camera, the user existing in the work space, acquiring, from a sensor which is hold by the user, distance information indicating distances between the sensor and each of the plurality of objects, determining a position of the user in the work space based on the three-dimensional model and the distance information, identifying a predetermined region closest to the position of the user among at least one of predetermined regions defined in the three-dimensional model, generating a display screen displaying the predetermined region and the image, and outputting the display screen to another computer.

Augmented reality device and method for providing assistance to a worker at a remote site

A sleepiness level detection method of determining a sleepiness level of a subject, includes: detecting a heart beat signal indicating a signal of heart beats from the subject and storing the heart beat signal in a storage device; detecting amplitude peaks of the heart beat signal and detecting an interval between the amplitude peaks as a heart beat interval; and computing a spectral density corresponding to fluctuation in the heart beat interval detected and determining the sleepiness level based on a maximum frequency at which the spectral density is maximum.
