Obstacle detection is one of the most important stages in the obstacle
avoidance system. This work is focused to explain the operation of a designed and
implemented for the overall detection of objects with low computational cost strategy.
This strategy of low computational cost is based on performing a spatial segmentation
of the information obtained by the SONAR and determine the minimum
distance between the SONAR (AUV) and the obstacle.
