Paper Abstract

Automatic target detection is very difficult in complicate background of sea and sky because of the clutter caused by waves and clouds nearby the sea-level line. In this paper, in view of the low-flying target near the sea is always above the sea-level line, we can first locate the sea-level line, and neglect the image data beneath the sea-level line. Thus the noise under the sea-level line can be suppressed, and the executive time of target segmentation is also much reduced. A new method is proposed, which first uses neighborhood averaging method to suppress background and enhance targets so as to increase SNR, and then uses the multi-point multi-layer vertical Sobel operator combined with linear least squares fitting to locate the sea-level line, lastly uses the centroid tracking algorithm to detect and track the target. In the experiment, high frame rate and high-resolution digital CCD camera and high performance DSP are applied. Experimental results show that this method can efficiently locate the sea-level line on various conditions of lower contrast, and eliminate the negative impact of the clutter caused by waves and clouds, and capture and track target real-timely and accurately.
