Optical navigation using one-dimensional correlation |
摘要 |
A technique for optical navigation involves summing intensity values from a photodetector array on a per-column and a per-row basis for both reference image data and sample image data and then performing separate one-dimensional cross-correlations on the per-column sums and on the per-row sums to separately determine displacement in the x and y directions, respectively.
