    Abstract: An obstacle detection device including: a plurality of ranging sensors configured to transmit ultrasonic waves and receive reflected waves thereof, and disposed on a vehicle to be spaced in a vehicle width direction; a camera disposed on the vehicle and configured to acquire an image corresponding to detection areas of the plurality of ranging sensors; and a control circuit configured to detect an obstacle around the vehicle, based on the reflected waves received and the image. The control circuit is configured to detect an obstacle, based on the image acquired by the camera during a predetermined period between transmission of an ultrasonic wave by a first ranging sensor and reception of a first reflected wave thereof, the image being acquired for a detection area of a different ranging sensor other than the first ranging sensor.

    Abstract: A system for analysis of sonar data is provided comprising sonar transducer assembl(ies), processor(s), and a memory. The memory includes computer program code that is configured to, when executed, cause processor(s) to receive sonar data, where an object is represented within sonar data, and additional data from a data source other than the sonar transducer assembl(ies). The processor(s) further determine object characteristic(s) of the object using sonar data and additional data, and determine an estimated object-type for the object represented within sonar data using the object characteristic(s). The processor(s) further generate a sonar image based on sonar data, cause display of the sonar image, and cause provision of an indication of the estimated object-type so that the indication of the estimated object-type is correlated to the object representation in the sonar image.

    Abstract: A system (1) is provided. The system comprises two primary sensor units (10) and two secondary sensor units (20). The secondary sensor units are configured to receive ultrasonic pulses during time windows, wherein a time window of the time windows comprises a corresponding transmit time of predetermined transmit times. The system is configured to determine a time-of-flight of an ultrasonic pulse of the ultrasonic pulses transmitted at a transmit time of the transmit times based on when the ultrasonic pulse was received during the corresponding time window. The system is further configured to determine a distance between two of the sensor units based on the determined time-of-flight between said sensor units. The system is configured to determine the positions of the sensor units in real-time based on measured movements and the determined distances.
