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

specific Embodiment

[0103] The active camera group selected in this example contains multiple active cameras, such as figure 2 , The active camera group is placed close to the radar, each active camera works independently, and an appropriate number of active cameras can be selected to track and observe the target according to the number of targets and the running direction of the target;

[0104] Such as figure 1 , Calibrate each camera, calibrate each (Cell group can include 1, 2, 4, 6, 8..., n adjacent Cell units), and store the results into the database of the data acquisition and display unit In figure 1 In, the Cell group can be the Cell unit corresponding to number 5, or the combination of the Cell unit corresponding to number 5 and any adjacent Cell unit (5 and 2, 5 and 8, 5 and 6, 5 and 4), or The combination of adjacent Cell units (5 and 1, 2, 4; 5 and 1, 2, 3, 4 and 6), the principle is that the Cell unit in each Cell group must have a common edge with other Cell units;

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...
