Accelerometer integration
Hey,
Despite this thread, I want to use accelerometers for a bit of navigation this year. In the attached excel spreadsheet, you can see that using the angles 0degrees 45degrees and 90degrees, I have found that the relation between the real acceleration and the output value is non linear and appears to be something like: y=(a^3)/12+500 where a is the real acceleration and y is the sensor value. My questions: 1)How can I convert this to a more linear connection? (do i need to?) 2)How do I integrate the values over time to get speed and more importantly distance? Thanks! -Leav Last edited by Leav : 22-01-2006 at 07:14. Reason: added excel file |
