Abstract

The invention discloses an object edge noise reduction method and a system for an infrared image. The method comprises the steps that step 1, obtaining the infrared image; step 2, carrying out frequency domain high-pass filtering on the infrared image and then carrying out spatial domain low-pass filtering to obtain a first image; and step 3, scanning the first image through an object edge detection algorithm and carrying out gray-scale smoothing to obtain an object edge image. The system comprises an infrared image acquisition unit, a first image acquisition unit and an object edge image acquisition unit. The method is mainly used in the technical field of image processing.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and system for reducing noise of an object edge of an infrared image. Background technique [0002] Biological images or thermal imaging images of other heat-generating entities acquired by infrared image acquisition equipment are relatively common, and its collision detection is a common problem. For areas with certain dangers such as lakes, hills and areas with potential subsidence, or buildings with confidentiality requirements, in order to prevent unintentional entry of unintentional personnel, it is often necessary to set up corresponding infrared monitoring equipment to monitor them around the clock. monitor. Such infrared monitoring equipment is often just a number of ordinary cameras set up on the periphery of the monitored area. In the control room, the monitoring personnel use the video data fed back by multiple cameras in real time to confir...
