摘要： The present invention provides a system and method for detecting and tracking a moving object. First, robust change detection is applied to find initial candidate regions in consecutive frames. These initial detections in consecutive frames are stacked to produce space-time bands which are extracted by Hough transform and entropy minimization based band detection algorithm.

摘要： Systems, methods, and devices are used to match images. Points of interest from a first image are identified for matching to a second image. In response to the identified points of interest, regions and features can be identified and used to match the points of interest to a corresponding second image or second series of images. Regions can be used to match the points of interest when regions of the first image are matched to the second image with high confidence scores, for example above a threshold. Features of the first image can be matched to the second image, and these matched features may be used to match the points of interest to the second image, for example when the confidence scores for the regions are below the threshold value. Constraint can be used to evaluate the matched points of interest, for example by excluding bad points.

摘要： A system and method for tracking a position of the Sun includes a solar tracker controller that generates directional control signals responsive to sensing signals. A solar tracking algorithm controls operation of the solar tracker controller responsive to the sensing signals. The solar tracking algorithm includes a rough tracking mode of operation for causing a pointing axis of at least one solar receiver to point generally in a direction of the Sun as indicated by the sensing signals. A searching mode of operation positions the at least one solar receiver such that sunlight falls on at least one solar cell of the receiver. A fine tracking mode of operation positions a pointing axis of the at least one solar receiver responsive to the feedback signal from the at least one solar receiver.

摘要： The present disclosure relates to systems, methods, and tools for tool tracking using image-derived data from one or more tool located reference features. A method includes: directing illuminating light from a light source onto a robotic surgical tool within a patient body, wherein the tool includes a plurality of primitive features having known positions on the tool, and wherein each feature includes a spherical reflective surface; capturing stereo images of the plurality of primitive features when the tool is within the patient body, wherein the stereo images are captured by an image capture device adjacent the illumination source so that the illumination light reflected from the imaged primitive features toward the image capture device substantially aligns with spherical centers of the surfaces of the imaged primitive features, and determining a position for the tool by processing the stereo images so as to locate the spherical centers of the imaged primitive features by using the reflected light.
