In other embodiments, a subset of depth image pixels is chosen through a process of “foreground segmentation,” in which the novel or dynamic objects in the scene are detected and selected. Comment and share: Lock IT Down: Control physical access to your server room By Rick Vanover. In these embodiments, sm is pruned by setting it to zero wherever the corresponding pixel in sm, is below a threshold θocc. Physical Security Systems Assessment Guide – December 2016 PSS-3 Appendix B (Access Control System Performance Tests) contains effectiveness tests on entry control and detection equipment. [0103] Templates that are updated over time with current image values inevitably “slip off” the tracked target, and begin to reflect elements of the background. In other implementations, the signal triggers a response suitable to the environment in which the access control system is implemented. Fortunately, the simple computations employed by this method are well-suited for high-speed implementation, so that it is not difficult to construct a system that operates at a rate where our predictions are reasonably approximate. For example, twofactor authentication access control might ask for a form of biometric identificationlike a fingerprint, and something the user knows, such as a PIN cod… By continuing you agree to the use of cookies. This foreground segmentation method is significantly more robust than other, prior pixel level techniques to a wide variety of challenging, real world phenomena, such as shadows, inter-reflections, lighting changes, dynamic background objects (e.g. If the new token 22 detected by token reader 14 is appropriately permissioned (step 92), access controller 16 registers the new person in a database and object detectors 12, 80 cooperatively track the movements of the new person within access control area 74 (step 94). In practice, the plan-view statistics for a given person become more noisy as he moves away from the camera, because of the smaller number of camera-view pixels that contribute to them. For the height SAD, a height difference of Hmax/3 is used at all pixels where TH has been masked to zero but sm masked has not, or vice versa. Each plan-view image contains one pixel for each bin, and the value at that pixel is based on some property of the members of the 3D point cloud that fall in that bin. Access control systems. The positional information of these points is derived entirely from a depth image. Kind Code: A1 . [0096] In these embodiments, if the best (minimal) match score found falls below a threshold θtrack, the Kalman state is updated with new measurements. [0053] With a stereo camera, orthographically projected, overhead views of the scene that separate people well may be produced. No. If the product has ever been hacked, you’ll want to know what steps the vendor has taken to make its technology more secure. More precisely, after tracking of known people has been completed, and after the occupancy and height evidence supporting these tracked people has been deleted from the plan-view maps, the occupancy map sm is convolved with a box filter and find the maximum value of the result. [0062] In some embodiments, rather than use all of the image pixels in building plan-view maps, only objects in the scene that are novel or that move in ways that are atypical for them are considered. The drawings are not intended to depict every feature of actual embodiments nor relative dimensions of the depicted elements, and are not drawn to scale. The random height difference is selected according to the probability distribution of all possible differences, under the assumption that height values are distributed uniformly between 0 and Hmax.
