Slowness of color pattern matching vi

Hi,

 

We're trying to implement a SLAM (simultaneous localization and mapping) algorithm in Labview based on kinect. In order to do so, the mapping robot should spot landmarks in real-time from the kinect image. We found the color pattern matching VI which does exactly what we need but the problem is that it's very slow (about 1.5 seconds for each image and total of 3 images each iteration). Is this the normal time for detecting landmarks in a kinect image? The robot can't map accurately when the iteration is so slow.

 

 

Thanks,

I would try to extract the luminance plane of the image, and use the grayscale pattern matching VIs instead. In addition to being faster, they're likely to provide better results than color pattern matching.
