specific Embodiment
[0074] The following combination Figure 4 The above-mentioned monitoring method is explained in detail.
[0075] The pan-tilt camera first uses a wide-angle focal length to shoot panoramic images on the waterway, specifically, every 30 seconds. Send the captured panorama to the AIS monitoring host (namely, the monitoring host), and the AIS monitoring host performs ship monitoring and processing on the panoramic image. Specifically, by obtaining the pixels of the last two panoramic images, subtraction is performed. When there is no movement on the channel If there is an object, the two captured panoramic images are the same, and after subtracting the pixels, each result obtained is 0, that is, a completely black picture is obtained. If the calculated image is not completely black, it means that there is a moving object, and it is judged that the moving object is a ship. In this way, whether there is a ship in the channel can be detected simply and quickly. After the ship is ...

The invention discloses an AIS monitoring system and a monitoring method for ships in an inland waterway, wherein the method includes the following steps: after collecting panoramic image information of the waterway, detecting whether there is a ship on the waterway according to the panoramic image information; When on a ship, control the working parameters of the pan-tilt camera according to the panoramic image information, and obtain the ship image information and the angle information of the pan-tilt; combine the ship image information, angle information and preset coordinate point information to obtain the coordinate information of the ship; collect AIS signals , and combine the AIS signal and coordinate information to identify ships that do not have the AIS system turned on. The present invention calculates the position of the ship by combining the image information, the angle information of the pan-tilt and the preset coordinate points, and combines the position and the AIS signal for matching and identification, so as to obtain the ship without the AIS system, which is convenient for the management personnel to manage the waterway. The safety of the waterway is improved, and it can be widely used in the field of river channel monitoring.
Description
technical field [0001] The invention relates to the field of river channel monitoring, in particular to an AIS monitoring system and monitoring method for inland waterway ships. Background technique [0002] For the safety of river travel, ships traveling on the river are required to be equipped with an AIS system. Through this system, the Maritime Safety Administration can obtain the information of passing ships, so as to facilitate the management of the river. However, in the actual ship operation process, some ships will deliberately turn off the AIS system to avoid supervision. When there are many ships running on the river, it is difficult for the Maritime Safety Administration to determine which ships do not have the AIS system turned on. In this way, the safety monitoring of the river has been seriously affected. [0003] Glossary: [0004] AIS system: Automatic Identification System (Automatic Identification System, AIS), is an automatic tracking system installed ...
