A stereo camera is a type of camera with two or more lenses with a separate image sensor or film frame for each lens. This allows the camera to simulate human binocular vision, and therefore gives it the ability to capture three-dimensional images, a process known as stereo photography. Stereo cameras may be used for making stereoviews and 3D pictures for movies, or for range imaging. The distance between the lenses in a typical stereo camera (the intra-axial distance) is about the distance between one's eyes (known as the intra-ocular distance) and is about 6.35 cm, though a longer base line (greater inter-camera distance) produces more extreme 3-dimensionality.

Tracking of retinal traction through digital image correlation
A tracking system for quantifying retinal traction on a retina of a patient eye includes an indicator device, a stereo camera, and an electronic control unit (ECU). The stereo camera collects and outputs stereo image data. The ECU, which is in communication with the indicator device, executes a method by receiving the stereo image data from the stereo camera during an ophthalmic procedure and thereafter assigning tracking points as coinciding pixels within stereo image pairs. The ECU also automatically performs a digital image correlation (DIC) process using the stereo image pairs to ascertain relative motion of the tracking points, and associates relative motion of the tracking points with the retinal traction using a traction map. A numeric traction quotient is generated that is indicative of magnitude of retinal traction. The ECU executes a control action using the indicator device based on the numeric traction quotient.

ActiveCN119941096BCharacter and pattern recognitionCo-operative working arrangementsStereo cameraMachine vision
This invention proposes a machine vision-based freight object tracking method, belonging to the field of visual tracking technology for logistics conveying objects. The method includes barcode recognition, volume measurement, and queue creation for freight objects. After the freight objects pass through the conveyor line, their volume is measured by a linear laser stereo camera, and then a conveyor line queue is created. Multidimensional features of the freight objects are acquired and added to the freight object queue information. Several mainline detection points are configured on the main conveyor line, and several branch line detection points are configured on several branch lines. The mainline detection points track the movement trajectory of the freight objects on the main line. When a freight object is about to transfer from the main line to a branch line, the identified freight object is removed from the mainline freight object queue and inserted into the end of the branch line freight object queue of the corresponding branch line. The branch line detection points further track the freight object. Through video measurement and tracking at multiple stages, the reliability and accuracy of the entire material object transportation process are improved.

Object detection device, object detection system, moving object, and object detection method
The object detection device includes a processor. The processor is configured to detect a straight line of a specified length by applying Hough transform to the coordinate points of the UD map, and detect the object disparity corresponding to the detected straight line of the specified length as the disparity corresponding to the object parallel to the direction of travel of the stereo camera. The UD map is a map in which the object disparity that satisfies a specified condition among the disparities obtained from the captured image is associated with coordinate points of two-dimensional coordinates consisting of a first direction and a direction corresponding to the magnitude of the disparity. The first direction corresponds to the horizontal direction of the captured image generated by the stereo camera capturing the road surface. The processor is configured to convert each coordinate point associated with the object disparity and a straight line of a specified range based on the vanishing point into the Hough space in the Hough transform.
