Objects shaking violently

By briand3d on Wed, 06/20/2012 - 17:07
I am using Unity extension Mac OS X 10.6.5 X code version 3.2.5 Unity 3.4 built from MacBook Prop, built onto an Ipad2 running ios 5. Using the unity extension, in a built scene using Augmented reality, I am getting a lot of shaking from projected objects. Instead of siting firmly on or around the image marker, the bounce around violently. I have no lights, my AR camera device mode setting is set to default, and the world center mode is set to auto, playing around changing these seems to have no effect This is similar to a previos post about a tall, however, I do not have the option of altering the projected objects shape. I will try and lay the objects horizontally on the marker, instead of standing upright, to see if that helps. Otherwise, is there some setting that cen be changed to help fix this.

Hi briand3d, Yes, do take a look at earlier posts in detail as there is a lot of discussion and ideas about this. The first thing is to ensure that the target is as large as possible in the camera view - most shaking problems are caused when the target is at the edge of detection.

What is the difference between the camera device mode settings? I have a 5 star marker here and the tracking is very shaky too (ipad2). Are there any parameter tweaks you can do (e.g.

(I've sent a private message just to discover whether I know you given the user name) The control to do this is in your hands - first try to keep the object size smaller than the target, and on a flat non-relective surface with minimal shadows and reasonable lighting conditions - all this helps.

Thanks, I'll have a look at that and see if it helps. Would be nice if other people how already dealt with shaking issues would post their experience.

Could please add the links to where these other discussions are taken place. It's hard to search or navigate this forum to find what you need. I have the same issue. My objects are smaller than the marker. I am outdoors when testing my AR so the sun is providing more than adequate lighting.

You'll need to implement any smoothing to the pose matrix from the Trackable. Some methods to investigate are statistical averaging, and low pass filtering of the changes in matrix values.

I have similar problem and I developed solution based on median filter. Current object position is calculated also in base of previous positions.
