Nvidia patents method to track object speed using radar and angle data
Nvidia describes a system that calculates how fast an object is moving by combining distance changes with angle measurements. It uses previous speed estimates to predict what the distance change should be, then compares that prediction to actual sensor data to refine the current speed estimate.
In the filing’s own words
One or more embodiments of the present disclosure relate to estimating a velocity of an object based on range rate measurements, angular measurements and one or more previously determined state estimates (e.g., previous velocity estimates) for the object. For example, an expected range rate for the object may be determined using an angular measurement and a previous velocity estimate of the object. The expected range rate may be compared with the range rate measurement to determine a velocity estimate for the object.
What exactly they claim (claim 1)
1. A machine comprising: one or more systems-on-a-chip (SoCs) individually comprising one or more central processing units (CPUs), one or more graphics processing units (GPUs), and one or more hardware accelerators; and one or more sensors having fields of view or sensory fields external to the machine, wherein the machine performs one or more control operations based at least on a velocity estimate corresponding to an object and determined based at least on: a range rate measurement corresponding to a portion of the object; and an angle measurement corresponding to the portion of the object.
