Abstract
A camera (), with suitable illumination (such as IR) provides images to a processing card () which converts the images to numerical vectors and applies them to a neural network () which is capable of providing a door-open signal () in response to something, either moving or still, in the paths of the doors (), or anything moving in a manner to indicate intent to enter the elevator in the landing adjacent to the elevator (). The door open signal is provided to the elevator door controller () to cause the doors to become or remain open in response to anything moving toward the elevator or anything disposed in the door pathway.
