Camera Modes (image is blurry)How Can i access/set Autofocus to the traking Object?

August 21, 2013 - 1:48am #1


On my Asus Transformer tf 300 t the camera image looks blurry and the focus seems to be not working correctly inside of my vuforia app.It seams that the tracking is dropping often, It only works if the Multitarget marker is relatively close to the camera. It seems that the app isn’t using the full resolution of the camera(should have 8 mp) The camera image looks quite dark as well. Is there a way to access the camera settings and tweak the recognition? Im Trying the Multitarget Sample.

In the camera app of the device the camera is  adjusting to light conditions of the environment.

Thank you very much for your answer. I have looked into exactly that script, from what i understand the focus mode is triggered if one is double tapping somewhere. Sadly I'm not noticing any difference with Continuous Focus on or of.


The focus of the Asus Transformers seams to be very slow since it is running better on my iPhone 5. Even the resolution of the video seams to be much higher on my Ipone, but maybe only the display has more contrast thus creaating that "illusion".

Could you describe what Trigger_Auto is doing? 


Do you have any suggestions of big a Multi Target should be in realty, i what to display very big objects, Like a 2m by 2m by 2m big virtual model of shelf position on a marker in the middel of a room so that the users could walk around the virtual thing. What is the correlation of The size of the marker an the Size of a virtual Model on the display?

The camera resolution used in Vuforia for the camera background rendering is usually lower than the maximum supported camera resolution for the device (e.g. 8mp).

For the focus, have you tried the CONTINUOUS_AUTO focus mode, and/or the TRIGGER_AUTO ?

(You can see examples of setting the focus mode  in Image Targets sample, see ImageTargetsMenu.cs script)
