Sea surface recovery target detection method based on eagle-eye-imitating vision and objectness

Abstract

The invention discloses a sea surface recovery target detection method based on eagle-eye-imitating vision and objectness. The sea surface recovery target detection method comprises the following steps: step 1, acquiring an objectness window image; 2, establishing an eagle-eye-imitating color space; 3, selecting an image with a relatively high score for subsequent processing; 4, calculating significance values of the same color; 5, eagle-eye-imitating color space smoothing processing is carried out; step 6, summing saliency results of the object-like window; and step 7, outputting a saliency detection result of the offshore recovery device. According to the invention, saliency detection is carried out on a window result of likelihood detection, so that the algorithm complexity of saliency detection is greatly reduced; according to the method, the eagle-eye-imitating color space is introduced into the process of detecting the saliency features of the object-like window, and the distance relation between pixels of a real image can be closer in the process of evaluating the image color space distance.

Description

technical field [0001] The invention relates to a research method for the saliency detection of sea surface recovery targets based on biological vision, in particular to a sea surface recovery target detection method based on imitation eagle-eye vision and similarity, and belongs to the field of computer vision. Background technique [0002] The full name of UAV is "unmanned aerial vehicle". It is an unmanned aircraft operated by radio remote control equipment and self-provided program control device. It is a high-tech product of the information age. [0003] With the three-dimensional and multi-level rapid development of modern naval warfare, small unmanned boats, unmanned ships, and intelligent floating recovery devices have many advantages such as convenience, flexibility, and autonomy, and can realize complex sea environments and dangerous oceans. The approach, survey and reconnaissance of the area and the unknown island environment have been more and more widely studied...

Problems solved by technology

Although the GPS navigation system can achieve all-weather uninterrupted positioning and navigation, but the GPS update frequency is slow and the accuracy is low, it cannot guarantee the real-time navigation of the UAV during the recovery process, and it is easily damaged and invalidated during special wars

The inertial navigation system does not send and receive information from the outside world. It has good concealment, strong anti-interference ability, and higher update frequency than GPS, but error accumulation will occur over time.

The combined navigation method can combine the advantages of various navigation methods to make the navigation system more accurate and reliable, but the cost of this navigation method is relatively high. When one of the navigation methods fails, the above-mentioned GPS navigation or inertial navigation will appear again. The shortcomings of the way
