StereoVision Imaging receives eight continuation patents for FMCW LiDAR technology
Human identification technology developer StereoVision Imaging (SVI) is internationally scaling its patent portfolio regarding the use of Frequency Modulated Continuous Wave (FMCW) LiDAR technology for biometrics and autonomous vehicles by receiving eight additional continuation patents to a collection of more than 100 global patents both granted and pending, the company announced.
The Dual Chirp FMCW LiDAR techniques can analyze the face to produce more than 20,000 points, each encrypted with range and speed measurement for accurate facial recognition detection that can be easily integrated in autonomous cars to prevent accidents by immediately detecting range and velocity of moving targets, the company explains.
This is of particular importance in the detection of moving faces or objects and critical information to eliminate all six degrees of freedom associated with a moving target resulting in a static, rigid template required for proper 3D facial or object recognition,” says Gregory Steinthal, Founder and President of SVI. “The extensive patent portfolio that we have amassed has also created a significant value proposition in the self-driving car industry. This same technology is absolutely crucial to instantly recognize other vehicles or objects moving towards them allowing for faster and more accurate decision-making efforts to avoid collisions.”
While typical FMCW LiDAR systems have their limitations such as not immediately detecting information such as range and range rate based on target signal or distance and velocity, or motion in relation to LiDAR sensor. SVI’s system uses a variety of up-chirped and down-chirped light beams from different laser sources to detect target motion, delivering faster and more accurate instantaneous determination of range and velocity measurements versus the traditional sequential approach, SVI says. The method can also be used to remotely detect physiological functions and can be used for acoustic surveillance integrated with video.
