Based on the problem that exists in the traditional camera that is applied to the airport, this application has provided a panorama high definition multiple focal distance camera device and system, as shown in fig. 1, demonstrates this application in the scene sketch map of panorama high definition multiple focal distance camera device in an embodiment. The application panorama high definition multi-focal distance camera device mainly through a plurality ofcamera array 100 that have different focuses to gather remote, well distance, and closely high definition image data simultaneously. The method and the device can be suitable for the full-range accurate monitoring of an ultra-large area, and output full-range high-definition images, high-degree dynamic capture and full-depth-of-field image shooting, and the scenes of both long-range scenes and close-range scenes can have the same resolution or definition.

Fig. 2 is a schematic structural diagram of a panoramic high-definition multi-focus camera according to an embodiment of the present disclosure. As shown, the apparatus comprises: acamera array 100 composed of a plurality ofcameras 110 having different focal lengths, for simultaneously acquiring high-definition image data of a long distance, a medium distance, and a short distance; and eachcamera 110 can work independently at the same time; eachcamera 110 has a digital zoom function with a certain zoom range, so as to provide continuous and stable high-definition image data when the image frame is stretched or zoomed excessively between a long distance, a middle distance and a short distance.

In an embodiment of the present application, thecamera array 100 at least includes: 1first camera 110A in close focus, 2second cameras 110B in mid-range focus, and 4third cameras 110C in far focus.

In one or more other embodiments, thecamera array 100 described herein may also include 2first cameras 110A, 4 or 5second cameras 110B, and 8 to 10third cameras 110C. That is, in the present application, thefirst camera 110A, thesecond camera 110B, and thethird camera 110C are not increased by multiples, and the number of settings is determined only by the screen sizes limited by the appropriate focusing ranges corresponding to the long distance, the medium distance, and the short distance, respectively.

In some embodiments, the camera device described herein employs acamera array 100 comprising a plurality ofcameras 110 with different focal lengths, so that a very wide coverage area, e.g., 42 ° vertical and 180 ° horizontal, can be achieved by the plurality ofcameras 110; in addition, thecamera 110 with different focal lengths can be used, so that various unprecedented high-definition images can be observed from a single position.

In this embodiment, thefirst camera 110A is a wide-angle camera 110, which is mainly used for capturing a panoramic scene, and thefirst camera 110A is mainly characterized by capturing a panoramic scene, and can clearly see a target object at a short distance, for example, a target object within 200 meters, but correspondingly sacrifices focusing at a long distance, that is, focusing on a target object at a long distance cannot be achieved or a high-definition image picture cannot be obtained.

Thesecond camera 110B is ageneral camera 110 or amiddle focus camera 110, and is used for capturing a middle distance scene, and it can clearly see a target object in a middle distance range, for example, the focusing range is set to be in a range of 500-1000 meters, although the focusing distance of thesecond camera 110B is increased, the capturing range is necessarily reduced, and therefore, at least twice the number of thefirst cameras 110A is needed to fill up the whole transverse scene. For example, one captures the left image and one captures the right image.

Thethird camera 110C is a long-focus camera 110 for capturing a long-distance scene, which can clearly see a target object in a long-distance range, for example, the focusing range is set to be more than 1000, and similar to thesecond camera 110B, although the focusing distance of thethird camera 110C is increased, the capturing range is necessarily reduced, so that at least twice the number of thesecond cameras 110B is required to fill the whole lateral scene.

In an embodiment of the present application, the high-definition image data acquired by thefirst camera 110A is a panoramic image; the high-definition image data acquired by thesecond camera 110B corresponds to the middle of the panoramic picture; the high-definition image data collected by thethird camera 110C corresponds to the upper portion of the panoramic image.

Referring to fig. 3, since the image captured by thefirst camera 110A is a panoramic image and a high-definition image of a close-range scene can be obtained, the image captured by thesecond camera 110B can be concentrated in the middle of the panoramic image, that is, the middle of the panoramic image corresponds to a middle distance, and the image captured by thethird camera 110C can be concentrated in the upper part of the panoramic image, that is, the upper part of the panoramic image corresponds to a long distance.

The digital zoom (digital zoom) is to enlarge each pixel area in a picture by aprocessor 112 in a digital camera, thereby achieving the purpose of enlargement. The method is similar to the method of using image processing software to increase the area of a picture, but the program is carried out in a digital camera, a part of pixels on the original CCD image sensor are amplified by using an 'interpolation' processing means, and the pixels on the CCD image sensor are amplified to the whole picture by using an interpolation algorithm. Digital zooming does not actually change the focal length of the lens. The principle is as follows: and judging the colors of the periphery of the existing pixels by using software, and inserting the pixels added by a special algorithm according to the color condition of the periphery.

In the present application, if the short-distance image frame is switched to the middle-distance image frame, the discontinuous image frame selection condition occurs, so that each of thecameras 110 is set to have a digital zoom function with a certain zoom range, so that the image frame can be stretched or zoomed excessively at a long distance, a middle distance, and a short distance to provide continuous and stable high-definition image data.

In an embodiment of the present application, the image frame of the close-range wide-angle view acquired by thefirst camera 110A is a default view; when a target object in the image frame needs to be observed, the target object is selected and amplified through an external communication device (such as a server or a terminal of an airport tower), thefirst camera 110A automatically performs digital zooming and transits to asecond camera 110B corresponding to the image frame containing the target object, specifically, the focusing distance of thefirst camera 110A gradually increases, and when a set limit value close to the minimum focusing of thesecond camera 110B is reached, the image frame acquired by thesecond camera 110B is automatically switched; and thesecond camera 110B automatically performs digital zooming and transits to thethird camera 110C corresponding to the image frame including the target object, specifically, the focusing distance of thesecond camera 110B gradually increases, and when the set limit value close to the minimum focusing value of thethird camera 110C is reached, the image frame acquired by thethird camera 110C is automatically switched.

As described above, compared with the prior art, the present application can realize all the functions of lens rotation, stretching, magnification, etc. in a digital analog manner, thereby eliminating the need for any mechanical part of the camera moving mechanism.

When a user selects a target object, such as an airplane ready to leave the field, the distance from the field airplane or thecamera 110 corresponding to the middle part of the panoramic picture is thesecond camera 110B, a local picture collected by thesecond camera 110B is displayed below the first picture, the distance from the field airplane is matched with the relative focal distance of thesecond camera 110B, and the local picture is displayed as a high-definition image picture which draws the field airplane closer. Therefore, the first panoramic picture and the local high-definition picture aiming at the target object can be simultaneously viewed.

For another example, if the selected target object is an airplane about to approach to the ground, the default frame or the first frame on the display is still the image frame with a close-range wide angle or a panoramic angle acquired by thefirst camera 110A, and the distance of the approaching airplane or thecamera 110 corresponding to the upper portion of the panoramic image is thethird camera 110C, a local frame acquired by thethird camera 110C is displayed below the first frame, the distance of the approaching airplane is adapted to the focus distance of thethird camera 110C, and the local frame is displayed as the image frame with a high resolution and a close-range airplane. Therefore, the first panoramic picture and the local high-definition picture aiming at the target object can be simultaneously viewed.
