Description:
This innovative 3D imaging system uses time-of-flight measurement of photons with a conventional global shutter CMOS camera to generate accurate distance data converted into brightness levels. It includes a laser source, camera, delay generator, master trigger, and electronic control unit (ECU) which together capture and average multiple jittered frames to produce normalized intensity images. These images are calibrated to create high-precision 3D point clouds capable of detecting objects over 50 meters away. The design focuses on simplicity, cost-effectiveness, and scalability, with potential enhancements through various camera technologies and on-chip integrations.
