Parallel tracking and matching for natural feature based AR registration[J]. Journal of Image and Graphics, 2011, 16(4): 680-685. DOI: 10.11834/jig.20110427.
A robust natural feature based parallel registration method is proposed. The method uses two threads for registration on a dual-core computer
one thread using KLT for tracking
while the other using Surf to reset the accumulated-errors. Delayed-homography is proposed to solve the problem of thread Synchronization. At the same time
the idea of key-frame
which is defined in this paper
increased the accuracy and stability of the registration. The experiment result proved that the multi-thread method solved the problem of accumulated-errors
and it is a robust feature based real-time registration method.
