Problems solved by technology

For the airport scene surveillance video, the aircraft only occupies a small part of the screen, and the appearance of the aircraft has a strong similarity with the background pixels, so the strategy based on mask matching will be greatly disturbed by the background
In addition, for the foreground pixels, there are usually large attitude, scale and position changes between the current frame and the first frame of the aircraft, which will cause the simple matching strategy to fail
[0007] To sum up, due to the particularity of airport ground monitoring, the current mainstream video object segmentation algorithms are not suitable for this scene

Embodiment Construction

[0057] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0058] Given the annotation of the first frame, many previous semi-supervised video object segmentation methods mainly explore the relationship between the current frame and the previous or first frame. However, if figure 1 As shown, due to the particularity of the airport ground surveillance video, each aircraft may suffer from spatio-temporal misalignment, resulting in the inability to find a satisfactory reference frame ...

Abstract

The invention discloses an airport scene monitoring video target segmentation method based on ADS-B position prior. Airport scene priori information ADS-B is applied to airport video target segmentation, and compared with a matching-based and propagation-based method, the method explores information from more previous frames in a reasoning process. According to the positioning information provided by the ADS-B, the content of the reference frame can be continuously updated, so that the reference frame is closer to the current frame. According to the scheme, the problem of space and time dislocation is solved, and the advantages of a propagation-based method and a matching-based method are combined, so that the network can continuously correct errors in the reasoning process, and the method has robustness for a long video.

Description

technical field [0001] The invention relates to the field of target recognition, in particular to an airport scene monitoring video target segmentation method based on ADS-B position prior. Background technique [0002] As an important technology of video processing, video object segmentation under airport scene monitoring plays a vital role in airport security. Given an aircraft of interest in the video, the video object segmentation algorithm continuously separates the object pixels of interest from the background until the object disappears or the video ends. This task plays an important role in airport surface surveillance systems. [0003] Divided from the setting, we can divide video object segmentation into unsupervised video object segmentation and semi-supervised video object segmentation. Among them, the unsupervised video object segmentation relies on the network to learn the semantic information in the video and automatically separate the foreground pixels from...
