Abstract

Technology about cycle sign’s center detection in industry photogrammetry was reviewed. Two mayor algorithms were analyzed theoretically and experimented including edge-detection method and intensity-weighted average method. The result shows that edge-detection method is vulnerable to noise and intensity-weighted average method is robustness which is more suitable to be used in actual works.
