The infrared camera of infrared ray, the embodiment of the present invention are not limited by the concrete type of infrared camera.
Fig. 6 diagrammatically illustrates the process according to the acquisition infrared image of the embodiment of the present disclosure and the method for visible images
Figure.
As shown in fig. 6, the method for acquisition infrared image and visible images includes operation S601~S602.
In operation S601, infrared image is first acquired using hybrid channel imaging sensor.
In accordance with an embodiment of the present disclosure, infrared camera and visible image capturing head can share identical camera lens, infrared photography
Head and visible image capturing head form hybrid channel imaging sensor.
In operation S602, switching hybrid channel imaging sensor is visible images acquisition channel, then acquires visible light figure
Picture, wherein infrared image is consecutive frame image with visible images.
In accordance with an embodiment of the present disclosure, hybrid channel imaging sensor may include infrared image acquisition channel and visible light
Image Acquisition channel.
In accordance with an embodiment of the present disclosure, when first acquiring infrared image using hybrid channel imaging sensor, can pass through
Infrared image acquisition channel first acquires multiframe infrared image, and when selecting frame image therein as Visual image processing
Reference picture.For example, can choose one acquired at first by two frame infrared image of infrared image acquisition channel elder generation continuous acquisition
Reference picture when frame infrared image is as Visual image processing.
In accordance with an embodiment of the present disclosure, switching hybrid channel imaging sensor is visible images acquisition channel, using can
Light-exposed camera continuous acquisition multiple image, and using the frame image finally acquired in the multiple image of continuous acquisition as visible
Light image.
Fig. 7 A diagrammatically illustrates the timing diagram of the acquisition infrared image and visible images according to the embodiment of the present disclosure.
Using hybrid channel imaging sensor as belt-type shutter sensor, the frame per second of belt-type shutter sensor be 60 frames/
For second, as shown in Figure 7 A, it (can be the 1/60th second) moment in t1, open infrared light-emitting diode lamp and issue infrared light, open
It opens infrared camera target object is shot and is imaged, obtains first frame infrared image (hereinafter referred to as IR_1)；T2 (can
To be the 2/60th second) moment, obtain the second frame infrared image (hereinafter referred to as IR_2)；It (can be the 3/60th second) moment in t3,
It is switched to visible image capturing head target object is shot and is imaged, obtains first frame visible images (hereinafter referred to as RGB_
1)；It (can be the 4/60th second) moment in t4, obtain the second frame visible images (hereinafter referred to as RGB_2).According to the disclosure
RGB_1 and RGB_2 can be used as image and shown by embodiment.RGB_1 and RGB_2 include interference source (for example, it may be
High intensity visible light source) in the case where, can also using in RGB_1 and/or RGB_2 a frame or two frames as eliminate IR_1
And/or the reference that the interference source in IR_2 influences, eliminating the interference source in IR_1 and/or IR_2 influences at least use as schemed
Operation S201 described in 2 and operation S202, details are not described herein.
Fig. 7 B diagrammatically illustrates the schematic diagram exposed when shooting according to the belt-type shutter sensor of the embodiment of the present disclosure.
As shown in Figure 7 B, for shooting to obtain IR_1, IR_2, RGB_1 and RGB_2 by Rolling shutter formula sensor,
Dotted line indicates to expose progress when shooting IR_1 in Fig. 7 B, by Fig. 7 B it is found that ensure that complete exposure function when shooting IR_1,
Oblique line indicates to shoot each frame image time course experienced.
Due to the characteristic of belt-type shutter sensor itself, consecutive frame image when shooting, timing be it is partly overlapping, change
Yan Zhi, when shooting previous frame image is not finished, and then a later frame image is begun to.When shooting due to consecutive frame image
Timing partly overlaps, if actively exposed to previous frame image IR_1, to a later frame IR_2 without exposure, then, it will be to rear
A part shooting of one frame IR_2 generates interference.In other words, after IR_1 is completed in shooting, the image of IR_2 includes being exposed
A part of and unexposed another part.Further, if actively exposed to IR_2, to a later frame RGB_1 without exposing
Light, then, a part shooting to a later frame RGB_1 is generated into interference.Therefore, because belt-type shutter sensor is when shooting
Existing characteristic itself can only use IR_1 if to improve the accuracy for eliminating that interference source influences in infrared image, without
Use IR_2.Therefore, when first acquiring infrared image using hybrid channel imaging sensor, it can use hybrid channel image biography
Sensor first acquires at least two frame infrared images, uses the first frame infrared image that acquires at first as the infrared of positioning target object
Image.
By above-mentioned analysis it is found that RGB_1 and RGB_2 are carried out it is background blurring, and when using IR_1 as referring to, by
It can be used as image in RGB_1 and RGB_2 to show, therefore, in every 4 frame image (including IR_1, IR_2, RGB_1 and RGB_2)
The background blurring image of 2 frames may finally be generated, every 2 frame image is equivalent to and obtains the background blurring image of 1 frame.
In accordance with an embodiment of the present disclosure, and so on, subsequent every 4 frame image is identical as t1~t4 acquisition mode.For example,
T5~t8 can acquire infrared image, infrared image, visible images and visible images respectively.
Fig. 7 C diagrammatically illustrates the timing of the acquisition infrared image and visible images according to another embodiment of the disclosure
Figure.
Using hybrid channel imaging sensor as belt-type shutter sensor, the frame per second of belt-type shutter sensor be 60 frames/
For second, as seen in figure 7 c, it (can be the 1/60th second) moment in t1, open infrared light-emitting diode lamp and issue infrared light, open
It opens infrared camera target object is shot and is imaged, obtains first frame infrared image (hereinafter referred to as IR_3)；T2 (can
To be the 2/60th second) moment, obtain the second frame infrared image (hereinafter referred to as IR_3)；It (can be the 3/60th second) moment in t3,
