Paper Abstract

Limitations inherent to the linear optical field assumption are discussed. A modified time-to-crash detector conception is proposed. The main features of our approach are a logarithmic compression of image in space, differentiation of the logarithm of light intensity in space and time, detecting local expansion using a nearest-neighbor logical circuitry, and an automatic choosing of the contour for the time-to-crash estimation. Keywords: optical flow, smart sensor, CMOS image sensor, motion sensor
