Method and system for automatic positioning and identifying target based on high definition video images

Abstract

The invention relates to a method and a system for automatic positioning and identifying a target based on high definition video images. The system comprises a high definition video image enhancement processing module, a target detecting and positioning module, a grayscale image binarization module, a target contour image inclination correction module, a target contour image dividing and feature extracting module, and a target contour image identifying and post-processing module. The system has the advantages that automatic target detecting and fast target positioning and identifying effect of high definition (above 2 million pixels) video images (moving) under complicated conditions is fine, high definition video image enhancement processing effect under uneven illumination conditions is fine, dynamic range is large, automatic target positioning and identifying precision are high and the like. In the meantime, reliability and stability of software is improved greatly by the design of an embedded software function, and construction mounting requirement of a front end embedded system (intelligent camera) is lowered.

Description

technical field [0001] The invention relates to a system and method for automatic positioning and recognition of targets based on high-definition video images, which can be used in complex scenes in the fields of public safety, parking management, intelligent transportation, and comprehensive emergency response. Background technique [0002] In recent years, high-definition cameras have been increasingly used in high-definition video image monitoring under complex backgrounds in the fields of public security, parking management, intelligent transportation, and comprehensive emergency response. The traditional standard-definition video image target positioning and recognition methods cannot be directly transformed into high-definition video image (moving) target (fast) Zigong positioning and recognition processing in complex scenes. It is difficult to detect (fast) automatic contour (edge) detection and positioning of (moving) targets in a fixed detection area. There are mult...

Problems solved by technology

The traditional standard-definition video image target positioning and recognition methods cannot be directly transformed into high-definition video image (moving) target (fast) Zigong positioning and recognition processing in complex scenes. It is difficult to detect (fast) automatic contour (edge) detection and positioning of (moving) targets in a fixed detection area. There are multiple (moving) targets in high-definition video images that need to be located and identified at the same time, while the existing target recognition methods for standard-definition video images are general. Can only identify a single target in a simple context
