Abstract

The invention provides a target characteristic parameter measuring device and method. The method includes: performing image fusion on a target image obtained by an infrared camera and a target image obtained by a visible light camera to complete target identification and tracking; combining a distance value of a target obtained by a laser range finder, an azimuth angle value and a pitch angle value of the target relative to an initial zero position obtained by an azimuth turntable and a pitch turntable, and a carrier position and an attitude angle value obtained by a GPS/INS combination system together, and calculating absolute position information of the target by applying a coordinate transformation matrix, and carrying out data processing on the real-time position of a moving target to obtain the speed and attitude characteristic parameters of the target. According to the method, continuous tracking of a dynamic/static target can be completed, the position coordinates of the static target, the position coordinates of the dynamic target, the speed, the course angle, the pitch angle and other information values can be given, the requirement for target characteristic parameter measurement in the field of unmanned ship automatic driving is met, and the method has wide application prospects.

Description

technical field [0001] The invention relates to a target characteristic parameter measuring device and method, belonging to the field of unmanned ship automatic driving. Background technique [0002] An unmanned ship is an intelligent surface platform that has autonomous obstacle avoidance, planning, and autonomous navigation capabilities, and can independently complete tasks such as environmental perception, target identification, and positioning. When the unmanned ship is navigating autonomously, the unmanned ship needs to be equipped with corresponding sensor modules, such as laser radar, satellite navigation system and photoelectric sensor, to realize the perception of the surrounding environment on the route, so as to reasonably plan the route and monitor the surrounding targets. monitoring etc. When the unmanned ship travels on the water surface, affected by the environmental characteristics of the water surface, the effect of lidar on environmental perception is not ...
