Abstract
Systems and methods for reducing error from noisy data received from a high frequency sensor by fusing received input with data received from a low frequency sensor by collecting a first set of dynamic inputs from the high frequency sensor, collecting a correction input point from the low frequency sensor, and adjusting a propagation path of a second set of dynamic inputs from the high frequency sensor based on the correction input point either by full translation to the correction input point or dampened approach towards the correction input point.
Claims15
A visualization system comprising:
- a first transmitter operable to transmit a first signal;
- an ultrasound transmitter operable to transmit an ultrasound signal;
- a first sensor operable to sense the first signal;
- an ultrasound microphone operable to sense the ultrasound signal;
- a delay measurement device connected between the first sensor and the ultrasound microphone and operable to determine a delay between receiving the first signal and receiving the ultrasound signal;
- a calibration system connected to the delay measurement device and operable to calibrate the first signal based on the delay;
- and
- a sensor digital processing unit connected to the first sensor to receive the first signal and operable to analyze the first signal to determine a location of the first transmitter and the first sensor relative to one another.
