Problems solved by technology

[0002] In practical applications, it is sometimes necessary to view the video screen locally or globally in multiple directions, but many existing industrial camera equipment cannot meet the needs of zooming, and manual zooming is required, which is not only time-consuming and labor-intensive, but also in application scenarios. In a wide range of situations, a fixed magnification often brings a lot of inconvenience

Embodiment 1

[0051] figure 1 Schematic diagram of the structure of the zoom system provided by the embodiment of the present invention.

[0052] see figure 1 , the zoom system of this embodiment includes:

[0053] The image acquisition module is used to acquire the video image of the target scene.

[0054] The control information processing module is used to obtain control instructions, and analyze the control instructions to obtain operation commands.

[0055] The target tracking module is respectively connected with the image acquisition module and the control information processing module, and is used to determine the tracking frame and miss amount of the tracked target according to the video image when the operation command is a target tracking operation.

[0056] The zoom module is respectively connected with the image acquisition module and the control information processing module, and is used for zooming the video image according to the size of the tracked target when the operat...

Embodiment 2

[0093] In this embodiment, three cameras are taken as an example to describe the zoom system in detail.

[0094] The image acquisition module includes three cameras, respectively a first visible light camera, a second visible light camera and an infrared camera; the first visible light camera is used to collect the first visible light video image; the second visible light camera is used to collect the second visible light video image; The infrared camera is used to collect video images of the infrared movement.

[0095] The overall implementation idea of ​​the zoom system in this embodiment is as follows: parallelly collect video images from two visible light cameras and one infrared camera, then first perform noise reduction and other processing on the video images, and encode the processed images through the real-time streaming protocol (Real Time Streaming Protocol, RTSP) pushes the stream to the remote device for display, then tracks the target selected by the system, and ...

Embodiment 3

[0120] The present invention also provides a zoom method, comprising:

[0121] Acquiring a video image of the target scene; obtaining a control instruction, and parsing the control instruction to obtain an operation command; when the operation command is a target tracking operation, determining the tracking frame and the miss amount of the tracked target according to the video image; When the operation command is a zoom operation, the zoom operation is performed on the video image according to the size of the tracked target to obtain a zoom image; the field angle of the zoom image is calculated, and the tracking frame, the The amount of miss and the angle of view are superimposed on the variable magnification image to obtain a superimposed image, and the superimposed image is sent to the ground station.

Abstract

The invention discloses a zooming system and method. The system comprises an image acquisition module used for acquiring a video image of a target scene; a control information processing module which is used for analyzing the control instruction to obtain an operation command; a target tracking module which is used for determining the tracking frame and the miss distance of the tracked target according to the video image when the operation command is the target tracking operation; a zooming module which is used for carrying out zooming operation on the video image according to the size of the tracked target when the operation command is zooming operation to obtain a zooming image; a system control module which is used for acquiring a tracking frame, a miss distance and a zoom image; and a video display module which is used for calculating a field angle of the zoom image, superposing the tracking frame, the miss distance and the field angle into the zoom image, and sending the superposed image to a ground station. According to the invention, automatic zooming can be realized, and the zooming efficiency is improved.

Description

technical field [0001] The invention relates to the zoom field, in particular to a zoom system and method. Background technique [0002] In practical applications, sometimes it is necessary to view the video screen locally or globally in multiple directions, but many existing industrial camera equipment cannot meet the needs of zooming, and manual zooming is required, which is not only time-consuming and labor-intensive, but also in application scenarios. In a wide range of cases, a fixed magnification often brings a lot of inconvenience. Contents of the invention [0003] Based on this, embodiments of the present invention provide a zoom system and method to realize automatic zoom and improve zoom efficiency. [0004] To achieve the above object, the present invention provides the following scheme: [0005] A zoom system comprising: [0006] Image acquisition module, for obtaining the video image of target scene; [0007] a control information processing module, confi...
