An active sensing device and method based on an unmanned ship

Abstract

The invention discloses an active sensing device and a method based on an unmanned ship. The device comprises an unmanned ship navigation control unit, a ship-borne laser radar device, a camera calibration unit, a data acquisition and display unit, a data transmission unit, a shore-based server control unit and a shore-based target detection unit. The shore-based target detection unit is used fordetermining the position of the target after detecting the complex water area target; the unmanned ship navigation control unit is used for controlling the unmanned ship to navigate to the vicinity ofa target to be observed;The ship-borne laser radar device is used for detecting a specific position of a target; the camera calibration unit is used for calibrating all the cell groups through the camera. The data acquisition and display unit is used for capturing a clear image of the object; The shore-based server control unit is used for storing the image data collected by the data acquisitionand display unit. The invention can greatly improve the clarity of photographed images and videos.

Description

Technical field [0001] The invention relates to computer vision technology, in particular to an active sensing device and method based on an unmanned ship. Background technique [0002] With the continuous development of science and technology, the shipping industry is playing an increasingly important role in the development of the national economy. The water entertainment industry in rivers and lakes is developing rapidly, and the level of automated security monitoring in complex waters that follows needs to be improved. The navigation environment is continuously deteriorating, and the safety of inland waterways is becoming more and more prominent. Therefore, it is particularly important to improve the monitoring intensity and level of complex waters. At present, the common monitoring method is fixed-point monitoring. A monitoring station is set up at a fixed location in the water area. It mainly includes camera monitoring, radar monitoring, and lidar monitoring. Radar monitori...

AI Technical Summary

Problems solved by technology

At present, the common monitoring method is fixed-point monitoring. A monitoring station is set up at a fixed location in the water area, mainly including camera monitoring, radar monitoring, and lidar monitoring. The weather with heavy fog and haze will fail. Similarly, the camera monitoring also has similar problems. The monitoring distance of the lidar is less than 100 meters, and the monitoring distance of the camera is only 2-4 kilometers. As the distance increases, the monitoring distance of the camera The worse the effect is, the radar monitoring can only detect the moving track of the target but cannot obtain the image and video of the target, that is, the intuitive monitoring effect cannot be obtained

The feature of this invention is to solve the problem of image shaking during the shooting process. However, this method cannot capture high-definition images of the target, and at the same time, it does not adjust the tracking speed of the video according to the speed of the target object. This method uses the sensor to locate the target. , and then track, however, the shooting point is fixed, and it is impossible to take a clear image of the target
