A system and method for determining a dimension of a target. The method includes: determining a camera parameter, the camera parameter including at least one of a focal length, a yaw angle, a roll angle, a pitch angle, or a height of one or more cameras; acquiring a first image and a second image of an target captured by the one or more cameras; generating a first corrected image and a second corrected image by correcting the first image and the second image; determining a parallax between a pixel in the first corrected image and a corresponding pixel in the second corrected image; determining an outline of the target; and determining a dimension of the target based at least in part on the camera parameter, the parallax, and the outline of the target.

Disclosed are systems, methods, and non-transitory computer-readable media for misaligned vantage point mitigation for computer stereo vision. A misaligned vantage point mitigation system determines whether vantage points of the optical sensors are misaligned from an expected vantage point and, if so, determines an adjustment variable to mitigate the misalignment based on the location of matching features identified in images captured by both optical sensors.

A medical/surgical microscope with two cameras configured to capture two dimensional images of specimens being observed. The medical/surgical microscope is secured to a control apparatus configured to adjust toe-in of the two cameras to insure the convergence of the images. The medical/surgical microscope includes a computer system with a non-transitory memory apparatus for storing computer program code configured for digitally rendering real-world medical/surgical images. The medical/surgical microscope has an illumination system with controls for focusing and regulating the lighting of a specimen. The medical/surgical microscope is configured for real-time video display with the function of recording and broadcasting simultaneously during surgery.

A calibration device for an imaging device includes an imaging data acquisition unit that acquires imaging data of a known external target installed at a known position outside a work range of work equipment, the imaging data being obtained by imaging of at least one imaging device provided in a work machine including the work equipment, an external target position acquisition unit that acquires a position of the known external target, and a calibration unit that calibrates the imaging device based on the position of the known external target, which is acquired by the external target position acquisition unit, and the imaging data of the known external target, which is acquired by the imaging data acquisition unit.

A multi-camera zoom control method and apparatus, and an electronic system and a storage medium. The method includes: in the process of a first camera collecting an image, if the current set magnification input by a user is in a magnification transition zone, starting a second camera; acquiring a corresponding stereo correction matrix on the basis of calibration parameters of the first camera and the second camera; calculating a translation matrix on the basis of an acquired pixel position corresponding relationship between the same content regions of interest that correspond to a first zoomed image and a second zoomed image and in combination with the current set magnification, and then calculating a smooth transition transformation matrix in combination with the stereo correction matrix; and performing, by applying the smooth transition transformation matrix, affine transformation on an image output by the first camera, to obtain a display image of a device.
