Analyzing accelerometer data: appropriate use of rotation matrices?

I'm working on a project in which a rod is attached at one end to a rotating shaft. So, as the shaft rotates from 0 to ~100 degrees back-and-forth (in the xy plane), so does the rod. I mounted a ...

“Quantifying” rotational acceleration from an accelerometer

I hope this post isn't too long, but I'm desperate for help and want to be pretty detailed/specific. I have recently built a system where a rod is attached at one end to a rotating shaft. So, as the ...

Decimation of motion

I have a motion signal that you can think of as a sequence of pairs (x,y); what would be the best approach to decimate this sequence at real time? I haven't found anything similar on the web and I'm ...

Correlating accelerometer data

I am getting a signal from a device. This signal contains a non-random noise signal in it. I want to remove that noise from the signal. This noise is correlated to the motion the device is having. So ...

Estimating device height from 3-axis accelerometer data (possibly by supervised learning)

I'm trying to estimate the height of my device using an cheap integrated Freescale accelerometer. First, I estimate the earth direction when measured acceleration is close to 1g, then I project the ...

'Best fit' motion curve for an unachievable profile

I have a discrete function that represents a 1d position in space over time. I have a motion system that would like to achieve this curve, but, due to constraints on jerk (3rd derivative) and ...

Using reference objects to estimate the point spread function?

I have a well-defined object and a clear image matrix of it. In subsequent frames the object moves, causing motion blur. I want to use the object as a reference to "guide" the deconvolution and ...
