摘要： This invention relates to a position/orientation measurement apparatus which can measure a position and orientation while achieving both high stability and precision. An image including indices laid out on a space is captured, and the indices are detected from the captured image. When a plurality of indices are detected, their distribution range is calculated, and an algorithm to be applied in position/orientation calculations is selected according to the size of the range (S3033, S3050, S3060). For example, when the indices are distributed over a sufficiently broad range, six parameters of the position and orientation of an image capture device are calculated as unknowns (S3070). As the distribution range of the indices becomes smaller, the degrees of freedom of unknown parameters to be calculated are reduced (S3035, S3025).

摘要： The first values of position and orientation of an image sensing device are obtained by using positions of all indices in a frame image. Indices having the same inherent information between a first index group (FIG) in the frame image and a second index group (SIG) in a preceding frame image are detected as a common index. If the information of the SIG contains information different from that of the FIG, second values of the position and orientation are obtained by using the positions of the common indices in the preceding frame image. If the information of the FIG contains information different from that of the SIG, third values of the position and orientation are obtained by using the positions of the common indices in the frame image. The first values are corrected by using correction values based on the obtained first to third values.

摘要： Indices are detected from a pattern image including a plurality of indices, and first positions of the detected indices on the captured image are calculated. Using parameters associated with an image capturing apparatus, second positions indicating the positions of the indices on the captured image are calculated. While a parameter of a radial distortion of a lens of the image capturing apparatus is fixed, the parameters other than the parameter of the radial distortion of the lens of the image capturing apparatus are corrected using the differences between the first positions and the second positions. Using the corrected parameters, third positions indicating the positions of the indices on the captured image are calculated. Using the differences between the first positions and the third positions, the parameter of the radial distortion is corrected.

摘要： An image capturing apparatus includes: a casing having an opening; a light source arranged inside the casing; a sensor arranged inside the casing and configured to capture, through the opening, an image of an object present outside the casing while the light source is on; and a distance calculator to calculate a distance between the casing and the object, based on an image that has been captured by the sensor and contains, within an image region of the object defined by the opening, a high-luminance region and low-luminance regions located more outside than the high-luminance region.

摘要： An apparatus includes: a light source; a two-dimensional image sensor that receives reflected light from a subject including specular light of the source and outputs an image of the subject; and an optical member arranged in an optical path of light emitted from the source to the subject. When a specular position of the source in the subject arranged apart from the two-dimensional image sensor by a certain distance is defined as a first specular position, whereas a specular position of the source in the optical member is defined as a second specular position, a relative positional relation of the optical member and the source with respect to the two-dimensional image sensor is determined so that a difference between an incident angle from the source toward the first specular position and an incident angle from the source toward the second specular position is a reference value or more.
