Abstract
A device and method of object detection in a scene by combining traditional 2D visual light imaging such as pixels with 3D data such as a voxel map are described. A single lens directs image light from the scene to a dichroic mirror which then provides light to a both a 2D visible light image sensor and a 3D sensor, such as a time-of-flight sensor that uses a transmitted, modulated IR light beam, which is then synchronously demodulated to determine time of flight as well as 2D coordinates. 2D portions (non-distance) of 3D voxel image data are aligned with the 2D pixel image data such that each is responsive to the same portion of the scene. Embodiments determine true reflectivity, true scale, and image occlusion. 2D images may be enhanced by the 3D true reflectivity. Combined data may be used as training data for object detection and recognition.
