Embodiment approach

[0115] In an implementation manner of the embodiment of the present invention, the step of obtaining the image to be detected collected by the security inspection device includes:

[0116] (1) Obtain the video collected by the security detector based on the radiation imaging method.

[0117] Specifically, the NVR device can receive the video sent by the image acquisition module of the security inspection device and collected based on radiation imaging. The image acquisition module of the security inspection device can send video through VGA (VIDEO GRAPHICS ARRAY, video graphics array).

[0118] (2) Decoding the acquired video to obtain an image to be detected.

[0119] The image acquisition module of the security inspection device sends the image to be detected in the video through VGA (VIDEO GRAPHICS ARRAY), and the image to be detected can be obtained through decoding.

[0120] In specific applications, multiple images obtained after decoding can also be compared with each...

Abstract

The embodiment of the invention provides a target detection method and device, NVR equipment and a security check system. The method comprises: acquiring a to-be-detected image collected by a securitycheck instrument; and identifying a target in the to-be-detected image, and determining the type of the target. By means of the technical scheme, it is unnecessary to depend on manpower to conduct target detection of a specified category on the to-be-detected image, the situation of missed recognition caused by fatigue can be avoided, and therefore the recognition precision can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a target detection method, device, NVR equipment (Network Video Recorder, hard disk video recorder) and a security inspection system. Background technique [0002] Security inspection instrument, also known as security inspection machine, is widely used in airports, railway stations, bus stations and other places. The security inspection device mainly includes an image acquisition module and a display screen. The image acquisition module uses X-rays to collect transmission images of luggage, and sends the collected transmission images to the display screen for display. In order to detect whether there are specified categories of items in luggage, such as knives, fireworks and other contraband, security inspectors need to quickly check the perspective images of X-ray scans, and use experience to identify the categories of items in the projected images. This metho...
