| Sumario: | This work presents an analysis of the behavior of some algorithms usually available in stereo
correspondence literature, with full HD images (1920x1080 pixels) to establish, within the
precision dilemma versus runtime applications which these methods can be better used. The
images are obtained by a system composed of a stereo camera coupled to a computer via a capture
board. The OpenCV library is used for computer vision operations and processing images
involved. The algorithms discussed are an overall method of search for matching blocks with
the Sum of the Absolute Value of the difference (Sum of Absolute Differences - SAD), a global
technique based on cutting energy graph cuts, and a so-called matching technique semi -global.
The criteria for analysis are processing time, the consumption of heap memory and the mean
absolute error of disparity maps generated. |
