### IMU and DSP - motion processing libraries

Are there any IMU / motion processing libraries for DSP? For example: I need to do motion pattern recognition from IMU data - accelerometer, gyroscope, magnetometer. Right now I'm playing with LCSS, ...

### Accelerometer - coordinate system transformation

I'm getting some accelerometer readings from an Android phone, but it comes in on the phone's coordinate system. I want to apply a transformation to put the acceleration in the world coordinate system ...

### Capturing images on fast moving conveyor belt

This may or may not be an image processing problem. I am developing a simple system that captures images of a part as they are being manufactured and sent out along the conveyor belt. I've solved ...

### How to form Kalman filtering matrices for a problem with variable acceleration?

Assuming we have time vector $T$ with constant time step $dt$ position vector $X$ velocity vector $V$ acceleration vector $A$ All vectors $X, V, A$ have noise on their measurement ( $n_x$ , $n_v$ ...

### 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 3-...

### 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 ...

### How can I improve my motion capture system?

Please excuse me if this is not the proper place to ask this. I just need some general advice. I have set up a very basic homemade motion capture system where I put three TrackIR cameras from ...

### '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 ...

### How to get translation and roation data using 6DOF MPU6150

I am trying to get the position data from an IMU 6 Degrees of Freedom (MPU-6150) board using an Arduino Uno. I am trying Jeff Rowberg’s example MPU6050_DMP6.ino that may be found here. This is the ...

### Deconvolution: Richardson-Lucy vs Wiener

I am studying some deconvolution techinques (to remove motion blur) like: Richardson-Lucy Wiener Are there any pros/cons of using one versus another? For example which are the pros/cons of ...
