Consider a camera that moves through a stationary environment. The time-varying range to features in the camera's field of view may be estimated recursively using a sequence of images. We study processing these images adaptively; our goal is accurate range estimation and increased range map density in the presence of constrained computational resources. The problem of autonomous nap-of-the-earth rotorcraft...

Development of an onboard obstacle detection and estimation scheme for low altitude rotorcraft fight is necessary both for the development of pilot warning system and as a step toward achiving fully autonomous flight. Vision sensors provide passive sensing of obstacles, and allow a wide field of view and nearly infinite range with relatively low cat. We consider the problem of estimating the relative...
