An imaging system substantially simultaneously acquires z-depth and brightness data from first sensors, and acquires higher resolution RGB data from second sensors, and fuses data from the first and second sensors to model an RGBZ image whose resolution can be as high as resolution of the second sensors. Time correlation of captured data from first and second sensors is associated with captured image data, which permits arbitrary mapping between the two data sources, ranging from 1:many to many:1. Preferably pixels from each set of sensors that image the same target point are mapped. Many z-depth sensor settings may be used to create a static environmental model. Non-correlative and correlative filtering is carried out, and up-sampling to increase z-resolution occurs, from which a three-dimensional model is constructed using registration and calibration data.
For use with a sensor system that includes first sensors to acquire z-depth and brightness data at a first resolution, and second sensors to acquire RGB data at a higher second resolution, said first and second sensors acquiring data substantially simultaneously, a method to combine data acquired by said first sensors with data acquired by said second sensors such that an RGBZ image may be rendered whose resolution is higher than said first resolution, the method including the following steps:
A time-of-flight system that acquires z-depth, brightness, and RGB information and outputs data from which an RGBZ image may be rendered, the range-finding system including:
