Abstract : During the human motion analysis it would be beneficial if it were accurate method for computing angles between segments using single camera and possibly even noncalibrated one. Main goal of this work was to test one possible such implementation based on rather familiar concept involving vanishing points and the image of the absolute conic. Proposed method evaluated with synthetic data is still inferior to ‘classical' ways of angle computation. Still, its attractive practical advantages warrant further investigation which should ultimately yield improvement in accuracy.
