I try to measure distances with the 3 axis accelerometer that is part of the lsm9ds1. therefore i measure the acceleration in x-axis and y-axis every 5ms and double integrate it over the time. I can already correctly measure the movement along the x- or y-axis with a precision +-1cm.
The problem is that, when i move the modul, in which the sensor is contained, along one axis, the data shows me that there is also an acceleration along the other axis. Because of this i get wrong distances when i move the module freely around the table. Has anyone experienced such behavior before and knows an answer? The data sheet of the lsm9ds1 Thanks in advance!
