Wikitude

Target image is not recognized

Hi Markus,

I figured it out. The problem was the misunderstanding of the code in the imagerecognition.jsl.
This is how it works for me:

this.tracker = new AR.Tracker("assets/carAdPC.wtc", { // name of the target collection
onLoaded: this.worldLoaded
});

// Create overlay for page one
var imgOne = new AR.ImageResource("assets/imageOne.png"); // name of the image to show
var overlayOne = new AR.ImageDrawable(imgOne, 1, {
offsetX: -0.15,
offsetY: 0
});

var pageOne = new AR.Trackable2DObject(this.tracker, "carAd", { // name of the image that was uploaded to create the target collection and not the name of the target collection itself
// at this point I was a bit confused
drawables: {
cam: overlayOne
}
});

Thank you so much for your help!

Hi Markus,

 

thank you for your answer. I tried again to create a wtc-file using the wikitude target management tool on your server. But the file I got, seems to be corrupted as well. I used the following combinations to upload the image and download the wtc-file: 

Mac OSX + Chrome and 

Windows 8.1 + FireFox.

Hi, I have the same problem. The wtc-files, I generated and downloaded with the Target Manager seems to be not valid.

What can I do to get a valid wtc-file. Maybe there is a work-around?

Thanks in advance

Hi,

 

I had a look at the files you posted. The image you posted should work all right for image recognition but it seems that your magazine.wtc is not valid (maybe it got corrupted during download).

Additionally, there is an error in your imagerecognition.js: when you name the image to be recognized surfer.png, your target will be named "surfer" and you have to set the according name for the AR.Trackable2DObject in line 24: 

var pageOne = new AR.Trackable2DObject(this.tracker, "surfer", {

   drawables: {

      cam: overlayOne

   }

});

 

Please update your .js accordingly and try the validated magazine.wtc attached to this post. If this is working within your sample, please try to re-generate the magazine.wtc yourself and cross-check if that is working as well.

If you encounter any more issues, please reply to this post.

Nicolas
