Visual Orientation in the Sewer Adaptation to the Environment
Most biological systems employ visually acquired information for their locomotion. In the course of evolutionary history, the visual system of organisms has evolved to be adapted to the environment. As a consequence of this adaptation, biological systems often display highly efficient visual skills. This reasoning has motivated the development of a specific visual system, which serves the purpose of navigation in an unusual environment ? a sewer. The sewer environment exhibits two dominating features: restricted geometry of its inner surfaces and absolute darkness. These features are exploited by the hybrid vision system of the autonomous robot consisting of a crosshair laser projector and a camera. If a priori knowledge about the sewer geometry is taken into account, orientation of the robot can be derived from a visual analysis of a regular laser pattern projected onto the sewer surface. Because the footprint image is acquired in an entirely dark environment, the camera records a mo...
