1. An obstacle detection device comprising:
an ultrasonic sensor signal processor configured to detect at least a distance to an obstacle among the distance to the obstacle and a shape of the obstacle based on an output of an ultrasonic sensor, the ultrasonic sensor being disposed on a door of a vehicle and configured to detect the distance to the obstacle within a predetermined detection range by an ultrasonic wave;
a camera image processor configured to detect the distance to the obstacle and the shape of the obstacle based on an output of a camera of the vehicle, the camera being configured to capture an image of an area including a trajectory range when the door of the vehicle is opened and a detection range of the ultrasonic sensor; and
a controller configured to perform open operation control of the door based on a comparison between a detection result of the ultrasonic sensor signal processor and a detection result of the camera image processor.
