An obstacle detection apparatus includes a distance measuring sensor, an imaging section, and a control section. Based on a reception result of reception waves obtained by the distance measuring sensor, the control section acquires an estimated reflection position in an illuminated region already irradiated with search waves. Based on the estimated reflection position, the control section recognizes an outer shape of an obstacle. Based on an imaging result obtained by the imaging section, the control section performs image recognition of the obstacle. Based on a recognition result of the outer shape of the obstacle and a result of the image recognition, the control section acquires a relative position, with respect to a vehicle, of a portion of the obstacle in an image captured by the imaging section included in a non-irradiated region ahead of the illuminated region in a vehicle traveling direction.

Disclosed is a system of tracking location of the listener's ears for 3D perception of audio signals sent from an array of acoustic sources. In addition to the array of acoustic sources, the system contains a video camera for finding a location of the listener's ears and one or more ultrasonic transducers for locating positions of the listener's ears by sending ultrasonic signals and receiving echoes reflected from the sought objects. The use of ultrasonic transducers enhances the action of the video camera and accuracy in positioning the listener's ears by calculating the distance from the acoustic sources to the plane in which the ears are located in the direction of axis Z, while the X, Y coordinates of the ears in the X, Y, Z coordinate system are determined by an image processor of the video camera.
