Method and apparatus for acquiring channel monitoring target

Abstract

Embodiments of the invention disclose a method and apparatus for acquiring a channel monitoring target. The method includes the steps of acquiring a first video frame of an infrared thermal imaging video; determining a target area in the first video frame; generating a Gaussian pyramid corresponding to the target area; and extracting eigenvalues of the Gaussian pyramid to carry out the local visual contrast calculation of the eigenvalues, and determining a first monitoring target from the target area according to the calculation result. In other words, the scheme is that the monitoring targetis acquired through the infrared thermal imaging video, an infrared thermal imaging video acquisition device is less susceptible to the weather as compared with a marine radar and a CCTV system, the infrared thermal imaging is still clear even in the case of bad weather and low visibility, such as fog days, rainy days and nights. Therefore, by using the scheme provided by the invention, the channel monitoring target can be accurately obtained.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a method and device for acquiring a waterway monitoring target. Background technique [0002] The monitoring of the waterway mainly refers to the monitoring of the ships in the waterway, so it is necessary to obtain the monitoring target (mainly the target ship), and the monitoring of the waterway can be realized by tracking the monitoring target. [0003] At present, a marine radar or a CCTV (Close Circuit Television Inspection, pipeline closed-circuit television detection) system is usually used to obtain channel monitoring targets. However, both marine radar and CCTV systems are susceptible to weather effects: when ordinary marine radar is affected by bad weather, the images produced are inaccurate, which leads to inaccurate monitoring targets; when the visibility of the CCTV system is low, For example, in foggy days, rainy days and nights, it is impossible to see the ship...

Problems solved by technology

However, both marine radar and CCTV systems are susceptible to weather effects: when ordinary marine radar is affected by bad weather, the images produced are inaccurate, resulting in inaccurate monitoring targets; when the visibility of the CCTV system is low, For example, in foggy days, rainy days and nights, it is impossible to see the ships in the water, so the channel monitoring target is not accurate.
