Drifting yaw angle after moving fast http://stackoverflow.com/questions/13613239/drifting-yaw-angle-after-moving-fast yaw angle after moving fast In my current project I ran into trouble regarding the quaternion provided by Core Motion's CMAttitude. I put the iPhone 5 iOS 6.0.1 at a well defined start position. Then I start to move the device quickly around.. from the start position for 10 20 degrees most of the time 1° . I used the old and sadly no longer available Core Motion Teapot sample to validate the effect. The Euler Angles for logging are read directly from CMAttitude NSLog @ pitch f roll.. hand I can hardly imagine that nobody had yet stumbled upon it. I suspect it might has to do with the redesigned Core Motion API. Starting with version 5 the magnetometer compass is considered for sensor fusion as well. Console shows that bias estimations..
Getting displacement from accelerometer data with Core Motion http://stackoverflow.com/questions/4449565/getting-displacement-from-accelerometer-data-with-core-motion displacement from accelerometer data with Core Motion I am developing an augmented reality application that at the moment wants to display a simple cube on top of a surface.. then press a button to reset the attitude. To find out the camera rotation is very simple with the Gyroscope and Core Motion. I do it this way if referenceAttitude nil attitude multiplyByInverseOfAttitude referenceAttitude CMRotationMatrix mat attitude.rotationMatrix.. arise anyway when I try to find the displacement in space during an acceleration. The Apple Teapot example with Core Motion just adds the x y and z values of the acceleration vector to the position vector. This apart from having not much sense..
