Problems solved by technology
[0002] The electronic waterway chart is based on the abstraction of geographical, hydrological and other data, and it is difficult to intuitively obtain more real and rich information about the entire inland navigation environment
The electronic lookout video system can observe the navigation environment more intuitively, but lacks abstract data information such as water depth and buoys
In the existing technology, the ship's electronic waterway chart platform and the electronic lookout video system are independent of each other, so that there is no information association and fusion between the electronic waterway chart and video images

Embodiment Construction
[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0049] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0050] In addition, in describing the present invention, the terms used are for the purpose of...

The embodiment of the invention discloses a method for superposing a ship electronic channel chart and a panoramic video image. The method comprises the following steps: acquiring an electronic channel chart image and a panoramic video image; matching the electronic channel chart image and the panoramic video image for calibration and registration, and obtaining a homography matrix of the electronic channel chart image projected to the panoramic video image; and projecting the electronic channel chart image to the panoramic video image through the homography matrix, carrying out weighted fusion to obtain a fused image, wherein data calibration is carried out through information of buoys during fusion so as to display information of all the buoys in the electronic channel chart image and the panoramic video image on the fused image. The embodiment of the invention also discloses a system for superposing the ship electronic channel chart and the panoramic video image. According to the invention, information association and fusion between the electronic navigation channel chart and the video image are realized, and inland waterway data and navigation environment are displayed more visually and richly.
Description
technical field [0001] The invention relates to the technical field of ship images, in particular to a method and system for superimposing ship electronic channel maps and panoramic video images. Background technique [0002] The electronic waterway chart is based on the abstraction of geographical and hydrological data, and it is difficult to intuitively obtain more real and rich information about the entire inland navigation environment. The electronic lookout video system can observe the navigation environment more intuitively, but it lacks abstract data information such as water depth and buoys. In the prior art, the ship's electronic waterway chart platform and the electronic lookout video system are independent of each other, so that there is no information association and fusion between the electronic waterway chart and video images. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a method a...
