Sea surface target radar plot condensation method, electronic equipment and storage medium

Abstract

The invention discloses a sea surface target radar plot condensation method, electronic equipment and a storage medium. The method comprises the following steps: acquiring a to-be-tracked binary image; obtaining an initial contour point according to the to-be-tracked binary image; obtaining a first target pixel point according to the initial contour point; searching a next target pixel point in the preset mask area according to a set sequence based on the current target pixel point; judging whether the next target pixel point is an initial contour point or not; and performing trace point condensation processing on the to-be-tracked binary image according to the mark state of the to-be-tracked binary image to obtain a trace point condensation result of the to-be-tracked binary image. The size of the preset mask area is (2m+1)*(2n+1), in the preset mask area, the first pixel point and the second pixel point meet the adjacent condition, and any two pixel points in the preset mask area meet the interconnection condition, so that the defect that a traditional contour tracking algorithm cannot extract a pixel point non-connected target contour can be overcome.

Description

technical field [0001] The invention belongs to the technical field of contour tracking, and in particular relates to a sea surface target radar point trace aggregation method, electronic equipment and a storage medium. Background technique [0002] Traditional sea target radar processing algorithms emerge in endlessly, but affected by external factors such as ocean waves, the distribution of clutter presents diversity and uncertainty. interference. Due to the low resolution of early radar, the radar target is only composed of one or a few points, and the processing of target point trace aggregation is relatively simple. With the improvement of detection accuracy, the target detected in the echo data is no longer a point target consisting of only one or a few points, but a cluster of traces surrounding the real position of the target composed of multiple original trace data. At the same time, there are more and more cases where the target is split and expanded. In the pro...

Problems solved by technology

However, with the precision of radar measuring instruments, the amount of target data obtained by the high-resolution radar receiver has greatly increased. When the target splits and expands, the pixels that make up the target in the radar image are disconnected. The traditional contour tracking algorithm will The target extracts two or more contours, and detects one target as multiple targets, resulting in misjudgment of the target

At this time, whether it is the processing speed of the system or the accuracy of the target information obtained after processing, the traditional method is far from meeting the requirements of the radar system.
