Embodiment 1

[0051] This embodiment provides a dual-spectrum camera capable of image fusion processing for real-time monitoring of a monitoring area. like figure 1 As shown, the dual-spectrum camera mainly includes an infrared imaging module 110 , a visible light imaging module 120 and an image synthesis module 130 . Wherein, the infrared imaging module 110 collects a thermal imaging image sequence of the monitoring area, and the visible light imaging module 120 collects a visible light image sequence. The image synthesis module 130 is connected with the infrared imaging module 110, receives the thermal imaging image sequence, and then identifies the target area in the thermal imaging image sequence of the monitoring area; the image synthesis module 130 is also connected with the visible light imaging module 120, receives the visible light image sequence, and combines the same Data fusion is performed on the thermal imaging image sequence and the visible light image sequence of the target...

Embodiment 2

[0077] The structure of the dual-spectrum camera provided in this embodiment is basically the same as that in Embodiment 1.

[0078] like Figure 7As shown, the difference is that the parallel-to-serial conversion unit 114 in the infrared imaging module 110 is implemented by programming a field-programmable gate array (Field-Programmable Gate Array, FPGA for short), and converts thermal imaging image information into a serial low-voltage differential signal (Low - Thermal imaging image sequence in Voltage Differential Signaling (LVDS for short) format, the repeating chip 116 adopts LVDS repeating chip, which can realize enhanced processing of LVDS signal.

[0079] The repeating chip 116 is connected to the image synthesis module 130 through an LVDS interface line. Wherein, the image synthesis module 130 includes an image combination sub-module 131 and an image processing chip 132 .

[0080] The image merging subunit 131 is preferably implemented by FPGA, and combines the the...

Abstract

The invention discloses a double-spectrum camera. The camera comprises an infrared imaging module, a visible light imaging module and an image synthesis module, wherein the infrared imaging module collects thermal imaging image sequences in a monitoring area; the visible light imaging module collects visible light image sequences in the monitoring area; and the image synthesis module is used for identifying a target area in the thermal imaging image sequences in the monitoring area and carrying out data fusion on the thermal imaging image sequences of the target area and the visible light image sequences of a same moment so as to generate a fusion image sequence in the target area. The infrared imaging module identifies a suspected target area in the monitoring area so that the visible light imaging module follows an identification result of the infrared imaging module in real time and a monitored visual angle of the visible light imaging module keeps consistent with a monitored visual angle of the infrared imaging module. A definition of monitored details in the target area is guaranteed and real-time detection and tracking can be realized.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a dual-spectrum camera. Background technique [0002] The dual-spectrum camera in the prior art is provided with an independent infrared camera unit and a visible light camera unit, wherein the infrared camera unit and the visible light camera unit use their own independent encoding chips for video encoding, and then complete the infrared image and visible light image through the host computer. Image Fusion Computation. [0003] This scheme needs to use an external host computer to synthesize the image or image sequence information about a specific scene acquired by two image sensors at the same time, and fuse the two images to generate a new image, so that the fused The image is more suitable for human perception or computer subsequent processing. This kind of system has a complex structure and is difficult to implement, and since the infrared camera unit and the visible light...
