摘要： A building access system for a building including a front facing camera system configured to capture one or more images of a face of a user, wherein one or more front facing camera processing circuits configured to detect and authenticate the user based on the one or more images captured by the front facing camera system and operate building equipment. The system further including a down facing camera system configured to capture one or more overhead images of the user from an overhead perspective, wherein one or more down facing camera processing circuits configured to detect whether a second user is tailgating the user based on the one or more overhead images captured by the down facing camera system and generate an alarm in response to a detection that the second user is tailgating the user.

摘要： A building radar-camera system includes a camera configured to capture one or images, the one or more images including first locations within the one or more images of one or more points on a world-plane and a radar system configured to capture radar data indicating second locations on the world-plane of the one or more points. The system includes one or more processing circuits configured to receive a correspondence between the first locations and the second locations of the one or more points, generate a sphere-to-plane homography, the sphere-to-plane homography translating between points captured by the camera modeled on a unit-sphere and the world-plane based on the correspondence between the first locations and the second locations, and translate one or more additional points captured by the camera or captured by the radar system between the unit-sphere and the world-plane based on the sphere-to-plane homography.
