Abstract

The present invention relates to a detecting method for small target based on column of infrared line detector in image processing technology field. The target is detected by using method of signal processing and mode identifying according with small target character in each single column scanned formed by each detector. The method needs not to detect target after reconstructing frame image for scanned field image, so detecting speed is increased, and image uneven influence is removed, and can response early. The target detection is processed for single column by using matching filtering, wavelet transformation and FKT arithmetic, and the detecting result is combined for constructing guide head signal process unit with rapid-speed and steadiness characters. The method can great increase target detecting efficiency using infrared column scanner by taking full advantage of scanned image character.

Description

technical field

[0001] The invention relates to a detection method in the technical field of image processing, in particular to a column-based weak and small target detection method in infrared column detector imaging. Background technique

[0002] Infrared imaging guidance is one of the important methods to realize precise guidance technology. In order to detect enemy aircraft, missiles and other targets as early as possible, the infrared imaging guidance system must capture the target as far away as possible. Weak and small targets are detected accurately. At present, there are two main forms of infrared imaging guidance technology, one is image scanning guidance using a combination of detectors and rotating optical-mechanical scanners, and the other is infrared focal plane imaging guidance. Because the cost of the former is low, it is easy to miniaturize, and the technology is relatively mature, so it still has a certain application range at present.
