Embodiment Construction

[0026] Referring generally to the drawings, systems and methods for night vision object detection and driver assistance are shown and described. Various sensor technologies, sensor configurations, and lighting technologies are disclosed that can be used to overcome problems with stereo vision systems (SVS) operating at night or in other weak surrounding environments.

[0027] The stereo vision system may include a camera system including a plurality of camera sensors for sensing objects. The stereo vision system includes a stereo camera system that includes two cameras that sense reflected energy in a wavelength interval from 0.9 microns to 1.8 microns (900 to 1800 nanometers). The stereo vision system is equipped with eye-safe supplemental lighting that is selectively activated during low light conditions. The stereo camera system may optionally include a third central camera, which may be used for data fusion techniques to add additional capabilities to the stereo vision sy...

Abstract

A stereo vision system includes a first camera sensor and a second camera sensor. The first camera sensor is configured to sense first reflected energy and generate first sensor signals based on the sensed first reflected energy. The second camera sensor is configured to sense second reflected energy and generate second sensor signals based on the sensed second reflected energy. The stereo vision system further includes a processor configured to receive the first sensor signals from the first camera sensor and configured to receive the second sensor signals from the second camera sensor. The processor is configured to perform stereo matching based on the first sensor signals and the second sensor signals. The first camera sensor is configured to sense reflected energy that is infrared radiation. The second camera sensor is configured to sense reflected energy that is infrared radiation.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to US Provisional Patent Application No. 61 / 976,930, filed April 8, 2014. The foregoing provisional application is hereby incorporated by reference in its entirety. Background technique [0003] The present disclosure relates generally to the field of stereo vision systems. More particularly, the present disclosure relates to stereo vision systems having features for improved operation during low light conditions, and to methods for detecting and tracking objects during low light conditions. [0004] Stereo vision systems may be incorporated into vehicles in order to provide a view ahead of the vehicle during night conditions and other poor environmental conditions, and may include multiple camera sensors. Stereo vision systems can be used to detect objects and estimate their position in the vehicle's path in three dimensions. Detection and estimation can be obtained from s...
