A processor of a distance measuring apparatus calculates a three-dimensional position of an object in the surroundings based on the first image, the second image and the amount of movement. The processor determines that calculated three-dimensional position is an error, when the displacement between a fourth position at which a third position set based on the calculated three-dimensional position of the object is projected on either one image of the first image and the second image and a position of the object in the one image is equal to or larger than a prescribed value. The processor makes the calculated three-dimensional position a distance measurement target when the calculated three-dimensional position is not determined as an error, and when determined as an error, excludes the calculated three-dimensional position from the distance measurement target.

An apparatus for determining a distance to a target area includes an imaging system configured to provide at least two images of a target area. The images are associated with different imaging axes. A Lidar system including at least one laser is configured to direct an optical beam to the target and an optical detection system configured to receive a portion of the optical beam from the target area and establish a distance to the target area based on the received portion.

An image for a left eye and an image for a right eye are respectively captured. A corresponding point corresponding to each of a plurality of feature points detected from the image for a left eye is searched for using the image for a right eye. The number of corresponding points found by the search is counted, and it is determined whether to be equal to or more than a predetermined ratio with respect to the number of pixels of the image for a right eye. When the number of corresponding points is determined to be less than the predetermined ratio, the image for a right eye is recaptured, and the corresponding point search process and the determination of whether the number of corresponding points is equal to or more than the predetermined ratio are re-executed using an image new for a right eye obtained by recapture.

A method for scanning an object having depths is provided, using a plurality of rod lenses to limit the blurring range of a contour image of an object having depths to enable an image capture unit to capture an identifiable contour image, wherein either of the diameter of each rod lens and the spacing between the rod lenses is smaller than the average width of the target. A scanning system for scanning an object having depths is also disclosed herein.

A microscope device includes an illumination optical system that illuminates a specimen with a light sheet, and a stereo image capturing device that captures images of the specimen in a plurality of different directions in which a resolution based on a triangulation method in a Z direction orthogonal to a direction of one or a plurality of light sheets formed on the specimen by the illumination optical system is less than a thickness in the Z direction of light sheet illumination that comprises the one or the plurality of light sheets.

An imaging platform and camera system with an oscillating platform having two dimensions or degrees of freedom of movement having three parallel axes about a single mounting position, an accelerometer, light meters, central processing unit, software techniques and sequence of imaging methodology to create a matrix of images by converting XYZ data into a 2-D matrix. A set of images, tagged with XYZ data at a range of degrees, are placed into the matrix. Adjacent, corresponding and opposite images for specific locations and object placement are captured. Patterns are created from sets of images previously photographed from exact XYZ coordinates that correspond to the 2-D matrix pattern, creating an illusion of 3-D oscillation of the objects, including dynamic texture, color and glimmer.

A three-dimensional non-contact scanning system is provided. The system includes a stage and at least one scanner configured to scan an object on the stage. A motion control system is configured to generate relative motion between the at least one scanner and the stage. A controller is coupled to the at least one scanner and the motion control system. The controller is configured to perform a field calibration where an artifact having features with known positional relationships is scanned by the at least one scanner in a plurality of different orientations to generate sensed measurement data corresponding to the features. Deviations between the sensed measurement data and the known positional relationships are determined. Based on the determined deviations, a coordinate transform is calculated for each of the at least one scanner where the coordinate transform reduces the determined deviations.

For obtaining two captured images suitable for a monocular stereoscopic method, without stopping the conveyance of a workpiece, a first pixel region is selected during the conveyance of the workpiece, and image capturing is performed. If it is determined that an image of a first mark member has been captured, a first pixel region is selected, and an image of the workpiece is captured.

Next, a second pixel region is selected, and image capturing is performed. If it is determined that an image of a second mark member has been captured, a second pixel region is selected, and an image of the workpiece is captured. Through the above imaging operation, two captured images to be used for three-dimensional measurement performed by the monocular stereoscopic method are acquired.

A terminal device used for stereo imaging includes: an image shooting unit; a communication unit that receives a first image of a first angular field from an external terminal device; and a determination unit that determines the image shooting range relationship between the first image received by the communication unit and a second image of a second angular field shot by the image shooting unit, the second angular field being wider than the first angular field.

A method is provided for calibrating a stereo imaging system by using at least one camera and a planar mirror. The method involves obtaining at least two images with the camera, each of the images being captured from a different camera position and containing the mirror view of the camera and a mirror view of an object, thereby obtaining multiple views of the object. The method further involves finding the center of the picture of the camera in each of the images, obtaining a relative focal length of the camera, determining an aspect ratio in each of the images, determining the mirror plane equation in the coordinate system of the camera, defining an up-vector in the mirror's plane, selecting a reference point in the mirror's plane, determining the coordinate transformation from the coordinate system of the image capturing camera into the mirror coordinate system, and determining a coordinate transformation.
