TextRecognition Postion

May 27, 2015 - 6:31pm #1

Vuforia SDK Version: 4.2.3 -

Description with steps to reproduce:

I have been playing around with the text recognition example that Vuforia supplies, I am trying to read the points of the corners that are used to render the mesh that overlays the text. What I get though is a very wierd printout that jumps between what looks like the correct points and some extremely out of place ones.

 

The printout onto the console is here:

 https://www.dropbox.com/s/7ykcfexnbvb26bg/VuforiaDebug.JPG?dl=0

 

APRIL is the word name, followed by the 4 Vector2 corner printouts, and the 0 was just the amount of words being tracked.

Seems wierd that it jumps from normal to extremely high and I don't think I can debug further to see why as I dont have access to the source code.

This was taken directly from the text recognition example.

var normals = new Vector2[4];
		for (var i = 0; i < 4; i++) {
			var p0 = corners[i];
			var p1 = corners[(i + 1)%4];
			normals[i] = (p1 - p0).normalized;
			normals[i] = new Vector2(normals[i].y, -normals[i].x);
		}
		
		//add padding to inner corners
		corners = ExtendCorners(corners, normals, mBBoxPadding);
		//computer outer corners
		var outerCorners = ExtendCorners(corners, normals, mBBoxLineWidth);

		print (outerCorners[0] + " " + outerCorners[1] + " " + outerCorners[2] + " " + outerCorners[3]);
