Abstract: A system includes a first camera defining a first camera coordinate system (C1) and configured to acquire a first image of a scene. A range sensor is spaced a first distance from the first camera and defines a range sensor coordinate system (R). A controller is operatively connected to the first camera and range sensor. The controller has a processor and a tangible, non-transitory memory device on which is recorded instructions for executing a method for obtaining a two-dimensional region of interest (u1*, v1*) in the first image, which is a two-dimensional intensity image. The first image is represented by a plurality of first points (u1, v1) in a first image plane. The controller is configured to acquire a range image of the scene with the range sensor. The range image is represented by a plurality of second points (u2, v2, d) in a second image plane.

Abstract: A vehicle exterior monitoring device obtains position information of a three-dimensional object present in a detected region, divides the detected region with respect to an horizontal direction into plural first divided regions, derives a first representative distance corresponding to a peak in distance distribution of each first divided region based on the position information, groups the first divided regions based on the first representative distance to generate one or more first divided region groups, divides the first divided region group with respect to a vertical direction into plural second divided regions, groups second divided regions having relative distances close to the first representative distance to generate a second divided region group, and limits a target range for which the first representative distance is derived within the first divided region group in which the second divided region group is generated to a vertical range corresponding to the second divided region group.

Abstract: A communication network comprising a collaborative photography group including a plurality of cameras having synchronized photographing times, is provided. The plurality of cameras may share location information, direction angle information, and image information generated by photographing an object, and generate a three-dimensional (3D) image of the object.
