The present invention provides an object recognition system for an autonomous mobile body. The object recognition system includes a sensor unit for detecting an obstacle in a target field of view and measuring the position of the obstacle, and an electronic control unit for controlling movement of the autonomous mobile body. The electronic control unit performs the functions of determining a velocity and a travel direction of the obstacle based on changes in the position of the obstacle obtained from the sensor unit over a plurality of measurement cycles, determining a still state of the obstacle, detecting that the obstacle has changed behavior if a current measured value of position of the obstacle deviates a predetermined angle from the previously measured travel direction or if it determined that the obstacle is standing still, and calculating, when a change in the behavior of the obstacle is detected, the velocity and travel direction of the obstacle anew starting at the position where the change has been detected.
