Abstract: A system adapted to identify the approach of an object. The system is adapted to: detect at least one object in space, provide an estimate of the distance between the at least one object detected and the system, and provide a time instant in which the at least one object is detected. The system defines a plurality of information sets, each information set referring to a time instant and a number of objects detected at the time instant, and including a distance from the device of each of the detected objects, the distances being ordered in a sequence according to a predetermined criterion, identifies pairs of information sets referring to different time instants but associated with the same number of detected objects. Further, the system generates an alarm signal if a change in distance or speed exceed a limit value.
Abstract: A system for measuring a distance of an object. The system includes a camera and a processing device connected to the camera. The camera captures an image that is received by the processing device. The processing device runs an image recognition algorithm that, for each object recognized in the acquired image, identifies a type to which the object belongs, and defines a bounding box that encloses the object. The processing device also determines a reference dimension of the bounding box. The computing device corrects the reference size of the bounding box of the recognized object by applying a correction criterion selected according to the value of at least one pre-stored parameter associated with the type of the recognized object and at least one feature of the bounding box of the recognized object. Then, the processing device calculates the distance to the object according to the reference dimension.
