StereoVision Imaging (SVI) has officially added five continuation patents to its portfolio of biometric and object recognition technologies. Four of those patents come from the United States Patent and Trademark Office (PTO), while the other comes from European Patent Office.
The news brings SVI’s portfolio to a total of 61 patents, with 46 patents still pending. The latest batch specifically concerns the company’s frequency modulated continuous wave (FMCW) LiDAR technology, which has applications in a number of different industries. Most notably, the technology can be used for surveillance and for biometric monitoring and identity verification.
To that end, the most significant of the new patents details a new Dual Chirp FMCW LiDAR system that uses multiple lasers to determine the range and velocity of a moving object faster and more accurately. The chirps refer to beam modulations that help gauge a Doppler shift or a beam reflection.
The other patents will improve the performance of various LiDAR applications. One concerns an eye tracking system, while another will help determine distance through a transparent surface, and a third improves video streaming, which will in turn enable more accurate facial recognition. The final patent uses LiDAR in conjunction with video images to determine the trajectory of a moving target.
SVI plans to integrate the technologies into its own products. It will also be licensing its IP to other manufacturers.
“These new patents continue and broaden the protection of our technology portfolio focused on detecting and measuring moving objects in real world situations,” said SVI president Gregory Steinthal. “As the owner of the first patents in the dual chirp 4D FMCW LiDAR space, we believe that we have established the furthest reaching IP portfolio for determining range and velocity, and we plan on exploiting this advantage fully.”
Steinthal suggested that the FMCW LiDAR tech could be used in autonomous vehicles. The company also provides technology for the US military, and recently received a $4.5 million order from the Army for its Facial Recognition Binocular System. SVI previously received a set of eight continuation patents in October of 2019.
