Embodiment Construction

[0060] Referring to the drawings, wherein like reference numerals designate like or similar parts throughout the several views, figure 1 Shows the coordinate system with a defined first camera (C 1 ) of the first camera 12 of the system 10. System 10 may take many different forms and include various and / or alternative components and devices. Although an exemplary system 10 is shown in the figures, the components shown in the figures are not intended to be limiting. Indeed, additional or alternative components and / or implementations may be used.

[0061] see figure 1 , the range sensor 14 is spaced a first distance 16 from the first camera 12 and defines a range sensor coordinate system (R). In one example, the lens 12A of the first camera 12 and the sensor portion 14A of the range sensor 14 may be respectively positioned in the first camera coordinate system (C 1 ) and the origin of the range sensor coordinate system (R). The first camera 12 and the range sensor 14 may b...

Abstract

A system includes a first camera defining a first camera coordinate system (C1) and configured to obtain a first image of a scene. The 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 the range sensor. The controller has a processor and a physical non-transitory memory device on which are recorded instructions for performing a method for a two-dimensional region of interest (u1*, v1*) in the first image, where is a two-dimensional intensity image. The first image is represented by a plurality of first points (u1, v1) in the first image plane. The controller is configured to obtain a range image of the scene via the range sensor. The range image is represented by a plurality of second points (u2, v2, d) in the second image plane.

Description

technical field [0001] The present invention generally relates to systems and methods for selecting a two-dimensional region of interest in a two-dimensional image using a range sensor. Background technique [0002] Two-dimensional images obtained from conventional digital cameras may include scattered and incoherent clutter, for example, in the background or other parts of the image. Typically, segmentation of 2D images may involve physical modification of the environment, such as adding a curtain to remove irrelevant background clutter. Electronic segmentation of two-dimensional images using only two-dimensional cues is time consuming. Contents of the invention [0003] A system comprising a first camera defining a first camera coordinate system (C 1 ) and configured to obtain a first image of the scene. The range sensor is spaced a first distance from the first camera and defines a range sensor coordinate system (R). For example, the lens of the first camera and the...
