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 This is a schematic structural diagram of a magnification variable system provided by an 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 the control instruction, and parse the control instruction to obtain the operation command.

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

[0056] The magnification module is respectively connected with the image acquisition module and the control information processing module, and is used for performing a magnification operati...

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, namely a first visible light camera, a second visible light camera and an infrared camera; the first visible light camera is used for collecting the first visible light video image; the second visible light camera is used for collecting the second visible light video image; The infrared camera is used to collect the video image of the infrared core.

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

Embodiment 3

[0120] The present invention also provides a method for changing magnification, comprising:

[0121] Obtain a video image of the target scene; obtain a control instruction, and parse the control instruction to obtain an operation command; when the operation command is a target tracking operation, determine the tracking frame and the miss amount of the tracked target according to the video image; When the operation command is a zooming operation, perform a zooming operation on the video image according to the size of the tracked target to obtain a zooming image; The missed target amount and the field of view angle 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 zoom system and method. The system includes: an image acquisition module, used to acquire a video image of a target scene; a control information processing module, used to analyze a control instruction to obtain an operation command; a target tracking module, used to perform a target tracking operation according to the video The image determines the tracking frame and the miss amount of the tracked target; the zoom module is used to perform a zoom operation on the video image according to the size of the tracked target when the operation command is a zoom operation, to obtain a zoom image; the system control module, It is used to acquire the tracking frame, the amount of miss and the zoom image; the video display module is used to calculate the field of view of the zoom image, superimpose the tracking frame, the amount of miss and the field of view on the zoom image, and send the superimposed image to the ground station. The invention can realize automatic zooming and improves the zooming efficiency.

Description

technical field [0001] The present invention relates to the field of variable magnification, in particular to a system and method of variable magnification. Background technique [0002] In practical applications, it is sometimes necessary to perform local or global multi-directional viewing of video images, and many existing industrial camera equipment cannot meet the needs of zooming, and need to be manually zoomed, which is not only time-consuming and labor-intensive, but also in application scenarios. In a wide range of situations, fixed magnification often brings a lot of inconvenience. SUMMARY OF THE INVENTION [0003] Based on this, the embodiments of the present invention provide a system and method for zooming, so as to realize automatic zooming and improve zooming efficiency. [0004] For achieving the above object, the present invention provides following scheme: [0005] A zoom system, including: [0006] The image acquisition module is used to acquire the v...
