Sensor e.g. accelerometer, calibrating method for e.g. drone, involves summing and integrating values to obtain total result, dividing result by known value to obtain estimation of bias, and calibrating sensor using bias

摘要

#CMT# #/CMT# The method involves determining two times (Ta, Tb), where a function value (V) and a real value (Y) of measured quantity are identical. Values (Zi) of sensors are connected from the time (Ta) to the time (Tb), and the values (Zi) are summed and integrated to obtain a total result (S). The result is divided by a known value to obtain an estimation of a bias (b), and a sensor e.g. accelerometer, is calibrated using the bias. #CMT#USE : #/CMT# Method for calibrating a sensor e.g. rate gyro, and accelerometer (claimed), embarked on a toy e.g. aircraft, drone and quadricopter, for measuring a physical unit. #CMT#ADVANTAGE : #/CMT# The method requires components already present on an inertial unit, and does not require temperature sensor, stellar navigation information, global positioning system navigator, geographical, radiometric or terrain information, so that the sensor can be calibrated in a simple and inexpensive manner.
