摘要： A determining method for obstacles includes determining whether an ultrasonic noise exists in TOF of an ultrasonic wave reflected by an object and received; generating a virtual object on an outline of a parking path that a vehicle is to move on based on the received ultrasonic wave TOF; generating virtual indirect wave TOF using the virtual object; and determining whether the object is located inside or outside the outline of the parking path by comparing real indirect wave TOF, which is indirect wave TOF among the received ultrasonic wave TOFs, with the virtual indirect wave TOF.

摘要： An object detection device includes a condition judgment unit and a noise processing unit. The condition judgment unit judges whether an execution condition for starting an object detection operation is satisfied. The noise processing unit performs a noise-related notification corresponding to an occurrence of limitation of an object detection function due to a high noise state when the condition judgment unit judges that the execution condition is satisfied and when the high noise state is established, the high noise state being a state in which a reception state of extraneous noise, different from the reflected wave received by the plurality of object detection sensors, exceeds a predetermined judgment criterion. The object detection device is configured to perform the noise-related notification more easily when a driving mode of the own vehicle is a backward driving mode than when the driving mode is a forward driving mode.

摘要： A method, system and computer program product for tracking movement of an object, such as a hand. Speakers of a device to be controlled transmit frequency modulated continuous wave (FMCW) audio signals. These signals are reflected by the object and received by the microphones at the controlled device. The received and transmitted audio signals are mixed. A fast Fourier transform (FFT) is then performed on the mixed audio signals. One or more peak frequencies in the frequency domain of the FFT mixed audio signals are selected and used to estimate the distance between the object and the speakers of the controlled device. Furthermore, the velocity of the object is estimated. The coordinates of the object are then computed using the estimated distance between the object and the speakers and microphones of the controlled device and the estimated velocity of the object.

摘要： An object detection apparatus is installed in a movable body and detects an object. The apparatus includes a first detection section which transmits search waves in a moving direction of the moving object, and receives reflected waves as detection information to detect the object, a second detection section which transmits search waves in the moving direction, and receives reflected waves as detection information, an obstacle determination section which determines that an obstacle is present in the moving direction, based on detection results of the first and second detection sections, and a crossing determination section which determines that the obstacle has crossed, in a state where the obstacle determination section determines that the obstacle is present, if the determination that the obstacle is present is made by continuous detection, and if a state where the object is continuously detected changes to a state where the object is not detected.

摘要： An active indoor location sensing technique is presented for smartphones and other types of mobile devices without requiring any additional sensors or pre-installed infrastructure. The main idea is to actively generate acoustic signatures by transmitting a sound signal with a phone's speakers and sensing its reflections with the phone's microphones. This active sensing achieves finer-grained control of the collected signatures than the widely-used passive sensing.
