Monitoring activities from multiple video streams: establishing a common coordinate frame
L. Lee,R. Romano,Gideon Stein +2 more
TL;DR: In this paper, a planar alignment matrix is used to align the scene's ground plane across multiple views and decompose the alignment matrix to recover the 3D relative camera and ground plane positions.
Proceedings ArticleDOI
Forward collision warning with a single camera
TL;DR: A vision based forward collision warning system for highway safety that computes time to contact (TTC) and possible collision course directly from the size and position of the vehicles in the image - which are the natural measurements for a vision based system - without having to compute a 3D representation of the scene.
Proceedings ArticleDOI
Vision-based ACC with a single camera: bounds on range and range rate accuracy
TL;DR: The range and range-rate from a single camera is discussed and the bound on the accuracy given a particular configuration is determined, which determines what steps must be made to achieve good performance.
Patent
Collision warning system
TL;DR: In this paper, a method of estimating a time to collision (TTC) of a vehicle with an object comprising: acquiring a plurality of images of the object; and determining a TTC from the images that is responsive to a relative velocity and relative acceleration between the vehicle and the object.
Proceedings ArticleDOI
Lens distortion calibration using point correspondences
TL;DR: A new method for lens distortion calibration using only point correspondences in multiple views, without the need to know either the 3D location of the points or the camera locations, which improves the accuracy of 3D reconstruction.
