In this obstacle detection system, if an obstacle has been detected by a front obstacle sensor or a rear obstacle sensor which has an obstacle detection range corresponding to the travel direction of the work vehicle, then a control unit displays the detected position of the obstacle on a display unit and performs collision avoidance control corresponding to the detection position of the obstacle; further, if an obstacle has been detected by a front obstacle sensor or a rear obstacle sensor which has an obstacle detection range not corresponding to the travel direction of the work vehicle, then the control unit displays the detected position of the obstacle on the display unit without performing collision avoidance control corresponding to the detection position of the obstacle.

A calibration method implemented by a computer, includes: measuring, with a laser ranging sensor, markers attached to at least two predetermined positions of a bed portion of a trampoline and calculating coordinates of the markers in a first coordinate system with a position of the laser ranging sensor being an origin; and calculating a conversion parameter to convert coordinates of respective positions of the first coordinate system into coordinates of respective positions of a second coordinate system with a center position of the bed portion being an origin based on a relationship between the calculated coordinates of the markers and the at least two predetermined positions of the bed portion.

An aircraft collision avoidance system includes a plurality of three-dimensional (3D) light detection and ranging (LIDAR) sensors, a plurality of sensor processors, a plurality of transmitters, and a display device. Each 3D LIDAR sensor is enclosed in an aircraft exterior lighting fixture that is configured for mounting on an aircraft, and is configured to sense objects within its field-of-view and supply sensor data. Each sensor processor receives sensor data and processes the received sensor data to determine locations and physical dimensions of the sensed objects. Each transmitter receives the object data, and is configured to transmit the received object data. The display device receives and fuses the object data transmitted from each transmitter, fuses the object data and selectively generates one or more potential obstacle alerts based on the fused object data.
