Abstract | ||
|---|---|---|
A reliable and precise estimation of optic flow is important for recovering 3D-shape in motion In actual scene analysis, however, the in- fluence of non-ideal condition^^)'^) should be taken into account. In this paper, we adopt an ex- tended constraint equation for determining under non-uniform illumination. We try to recover 3D- shape from an image sequence under non-uniform illumination by introducing additional constraint equations of anisotropic constancies in optic flow and creation rate of brightness. We also propose a new concept of vision system for mobile robot carrying an illumination source in the night. in the estimation of optic flow, and propose a vi- sion system for mobile robot carrying an illumina- tion source in the drak environment. A proposal to extend the gradient-based method is tested to esti- mate the optic flow. We also propose additional con- straint equations to determine optic flow field under non-uniform illumination. The effectiveness of the proposed method is confirmed by (using) artificial and real image sequences. |
