IEEE Wash/NoVA Sensor Council Seminar: Michael Powers, "LADAR and Robotics"
IEEE Washington/NoVA Sensor Council Chapter seminar
Dr. Michael Powers
This talk begins with an introduction to LADAR and an overview of its many variations and applications. The emphasis turns to autonomous vehicle / robotic applications, where LADAR is often an essential sensor for real-time perception and navigation. The perception requirements for autonomous vehicles are demanding and seldom satisfied by off-the-shelf sensors. State-of-the-art perception systems usually combine data from several disparate sensors, but this approach has significant drawbacks. Spectral LADAR, which is to be described in detail, was developed to overcome the limitations of the data fusion approach by unifying time-of-flight ranging and active multispectral imaging based on a supercontinuum optical transmitter. The 3D spatial and multispectral capability of Spectral LADAR is well suited to imaging in complex and cluttered environments, thereby enabling high-fidelity “world models” to drive sophisticated autonomous operations. Results from a variety of scenes will be presented to illustrate its advantages relative to alternative methods including sensor data fusion. The experimental results obtained with a laboratory prototype point to additional imaging applications where combined spatial and spectral information is valuable.
The scope broadens to consider recent advances in optical devices and signal processing that have the potential to radically alter the landscape of optical imaging systems. The talk concludes with a forecast of how these developments will influence the evolution of LADAR systems beyond historical and contemporary architectures.
