Description

[0001] Method for displaying and updating a panoramic image of a landscape

[0002] The invention relates to a method for displaying and updating a panoramic image of a landscape, comprising a display means and at least one camera, with the image angle of which a section of the image angle of the panoramic image can be captured, wherein the position of the camera can be controlled within the range of the image angle of the panoramic image, with the step: (i) displaying the panoramic image on the display means. The invention also relates to a terminal for displaying and updating a panoramic image of a landscape, comprising at least one camera, with the image angle of which a section of the image angle of the panoramic image can be captured, and a display means on which the panoramic image can be displayed, wherein a control and processing unit is connected between the camera and the display means and is designed to (i) display the panoramic image on the display means.

[0003] In the current state of the art, live panoramic videos generated by an initial set of cameras (the panoramic cameras) are used in various applications, such as broadcast productions or remote air traffic control (ATC) towers. At the same time, additional PTZ cameras are deployed to display details of the scenery depicted in the panoramic videos with a greater zoom factor (making them more visible to the viewer) (example: a landing aircraft in a panoramic video from a remote ATC tower application, which the controller needs to see in detail in order to be able to assess whether the aircraft's landing gear is extended). The panoramic cameras are positioned in the immediate vicinity, ideally directly above or below the controllable PTZ camera.This has the following disadvantages: A second camera system is required to record the panoramic video; camera systems for recording panoramas with a field of view of more than 180° are very expensive; the camera - e.g. a PTZ camera - and the panoramic camera system must be manually calibrated to each other, which is time-consuming and must be repeated every time there is a change in position or orientation of one of the two cameras; the image processing used to generate the panorama causes a delay in the video display, which impairs the precise control of the PTZ camera; the bandwidth required for digital data transmission via IP is disproportionately high (up to 80% of the total video bandwidth).

[0004] CN1 12991 175 teaches a method and system for creating a panoramic image from a set of individual shots taken during a PTZ camera movement. Adjacent individual shots are arranged in an overlapping manner so that the image content is uninterrupted. A disadvantage here is that there is no solution for updating the panoramic image, once created, according to useful criteria.

[0005] CN106296584 discloses a method for inserting a video image, e.g., from a live camera, into an existing panoramic image. This solution is rigid and can only process a predefined video image size. WO2018232412 relates to a method in the field of cartography, with which a sequence of images with increasing zoom factors is stored for sections of a predefined panoramic image, allowing zooming into any position of the panoramic image. A method for updating, monitoring, or video display of the panorama or parts thereof is not specified.

[0006] The object of the invention is to overcome the disadvantages of the prior art and to generate and update a panoramic image for monitoring or control purposes using simple equipment, while also ensuring resource-efficient data transmission. The solution should simultaneously be low-maintenance, reliable, easy or intuitive to operate, and cost-effective.

[0007] The method according to the invention achieves this by the steps: (ii) panning the camera to a predetermined position and taking a picture,

[0008] (iii) Comparison of image properties of the image with reference values ​​of the section of the panoramic image in which the image is to be inserted,

[0009] (iv) either inserting the image into the position of the section of the panoramic image if the reference values ​​are met, (v) or adjusting the image in terms of contrast, zoom factor, and / or brightness until the image properties meet the reference values, whereupon the image is inserted into the section of the panoramic image. In an advantageous embodiment of the invention, a selection of image pixels from the panoramic image is used as the basis for the reference values, with the contrast values ​​of the image pixels serving as the reference values. This makes updates optically more uniform and avoids inserting faulty images. Contrast values ​​are a constantly present and readable pixel property.

[0010] It is also thought that a panoramic image is created beforehand with the following steps:

[0011] Create a set of images by the camera as photos in the angle of view of the panoramic image to be created by repeating the steps:

[0012] (a) taking a first photograph at a first position,

[0013] (b) Adding metadata to the first photo,

[0014] (c) Moving the camera to the next position and stitching the images side by side with a predetermined overlap and using the metadata. This creates a panoramic image in a format that already corresponds to the system.

[0015] Overlapping areas of adjacent images can also be blended semi-transparently. This also improves the visually uniform display.

[0016] In a further development of the method, overlapping areas of adjacent images are blended to 10%-30% of the area of ​​the images, which corresponds to a balance between technically secure overlap and low area losses.

[0017] In an advantageous embodiment of the invention, at least one camera is a PTZ camera, as this is a camera type that is easy and reliable to control. It is also contemplated that the method is carried out with at least two cameras, each capturing images in the form of photos and videos. This small additional expenditure on equipment enables the advantage of displaying more than one moving object in the panoramic image in an updated manner.

[0018] An application can also be provided that identifies a terrain edge on the horizon of a landscape in a panoramic image. The camera creates a video with an adjustable zoom factor depending on the camera position and angle of view, such that the terrain edge, as well as a predetermined angular range of the terrain horizontally below the terrain edge, are included in the video. This allows an operator to always identify a flying object in relation to the ground below it and thus assess the situation more reliably.

[0019] In a further embodiment of the method, at least one graphic overlay is inserted, and wherein the graphic overlay contains in particular information about objects and / or events in the area of ​​the scenery depicted in the panoramic image, whereby the operator is provided with additional important information about events in the panoramic image, so that he receives this information when looking at this panoramic image and does not have to look at separate display instruments.

[0020] In an advantageous embodiment of the invention, depth information is visibly inserted in one or more areas of the panoramic image in order to again communicate to the operator additional important information about states of objects or events in the panoramic image.

[0021] It is also conceivable that a video could be displayed in the angle of view of the panoramic image and in a separate window or other display device from the displayed panoramic image, with the image resolution of the separate display differing from the image resolution of the video inserted into the panoramic image. This allows the operator to view a selected section of the panoramic image in a larger format, allowing the operator to recognize details better in this enlarged section than in the panoramic image.

[0022] The camera's orientation can also be based on position data from third-party sensors, in particular from at least one transponder, at least one ADS-B transponder, and / or at least one radar. This allows decisions about positions to be updated in the panoramic image to be made automatically. Furthermore, objects can be displayed in the panoramic image at a position where they are not yet close enough to be visible.

[0023] In a further development of the process, the camera is aligned via a user interface based on click and / or touch commands from an operator. This allows the operator to easily select the section of the panoramic image that needs to be updated.

[0024] According to an alternative embodiment, the orientation of the camera can be dependent on the viewing direction of the operator, which also allows a very simple and intuitive control of the camera orientation by the operator.

[0025] In another embodiment, the operator's viewing direction is determined using virtual reality (VR) glasses worn by the operator. This advantageously makes control simpler and more intuitive, while simultaneously reducing the equipment required to implement the method.

[0026] The terminal according to the invention achieves the above-mentioned object together with the above-mentioned advantages in that the control and processing unit is further designed to

[0027] (ii) to pan the camera to a predetermined position to take a picture,

[0028] (iii) to compare the image properties of the image with reference values ​​of the section of the panoramic image to which the image is to be joined,

[0029] (iv) insert the image into the section of the panoramic image if the second set of reference values ​​is met, or (v) adjust the image in terms of contrast, zoom factor, and / or brightness until the image properties meet the reference values, whereupon the image is inserted into the section of the panoramic image. In an advantageous embodiment of the terminal, the at least one camera is a PTZ camera, as this is a camera type that is easy and safe to control.

[0030] It is also envisaged that the control and processing unit is connected to a receiver for aircraft transponder data and / or radar data. This allows information to be received that can be helpfully displayed to an operator as additional information in the panoramic image.

[0031] The control and processing unit can also be connected to a user interface. This allows the operator to easily select the section of the panoramic image that needs to be updated.

[0032] Exemplary embodiments of the invention are schematically illustrated in the drawings and are described below by way of example with reference to the drawings. Figures 1 to 3 show three simplified panoramic images; Figure 4 shows the merging of a panoramic image from three individual shots; Figure 5 shows a panoramic image with graphic overlays; and Figure 6 shows a panoramic image of an airfield with a high-resolution zoomed image of an aircraft, as well as a corresponding representation within the static panorama (scaled to the correct size and embedded), as well as its separate representation in full resolution.

[0033] Using the example of remote airspace or airfield monitoring (remote tower application), the procedure and the terminal offer a replacement of the bandwidth-intensive video panorama with a static panorama, which takes approx.

[0034] This saves 80% of the transmission bandwidth of previous remote tower applications. At the same time, the air traffic controller is offered almost equivalent situational awareness, enabling them to handle one to three simultaneous flight movements safely and efficiently. The number of flight movements depends on the number of cameras used. A so-called remote tower can now also be used where the available network bandwidth between the airport and the air traffic control terminal is low. In the following, parts of a panoramic image 2 are replaced by current recordings, whereby "recording" can refer equally to photos or videos, i.e., moving image recordings, unless one of these can be excluded in a technical context.

[0035] According to Fig. 1 to Fig. 3 and following, a method for camera control for a camera 1, such as a pan-tilt-zoom camera (PTZ camera for short), via a 2-dimensional, static panoramic image 2 is specified. The panoramic image 2 is generated directly by the PTZ camera without the aid of another camera and is continuously updated. The PTZ control is then carried out by click or touch inputs of an operator via a suitable user interface. This interface can be a touch-sensitive screen on which the panoramic image 2 is directly displayed. The PTZ camera is

[0036] Input automatically aligned in the direction of the corresponding position. In addition, the 2-dimensional panoramic image 2 can be stored with depth information, and the zoom factor and the focus can be controlled automatically. According to a particularly easy-to-use alternative, it can be provided that the camera depends on the operator's direction of view, whereby the operator's direction of view is determined with or without virtual reality glasses (VR glasses) worn by the operator. If VR glasses are used, which the operator wears, they serve simultaneously as a display means and as a control of the PTZ camera by the operator. The current direction of view of the operator and changes to this direction of view are detected with the help of the VR glasses sensors and the PTZ camera is aligned according to this direction of view or changes thereto. In this embodiment, the panoramic image 2 is displayed in the VR glasses.VR glasses are equipped with tilt and motion sensors that enable the detection of the operator's viewing direction and any changes in the viewing direction. As shown in Fig. 6, a live video from the PTZ camera is overlaid onto the previously created static panorama image 2 in order to update the static panorama image 2 at the points where important events are taking place for the operator (e.g., an aircraft is flying). The live video from the PTZ camera is scaled according to the set zoom factor and displayed as section 6 within the panorama image 2 at the correct position. This creates the impression of working with a live panorama video, since the area or section 6 covered by the PTZ camera is displayed as a moving image in the panorama image 2.The system and / or the operator have sufficient information about the events and weather within the field of view of panoramic image 2 to assume that the areas outside of the live video section 6 are unchanged and motionless, and therefore still sufficiently up-to-date. At least for a certain period of time, areas of panoramic image 2 outside of the live video section 6 can therefore be displayed unchanged as a still image. This is the case, for example, if the parked aircraft at the airfield are not moving in unchanging weather conditions.

[0037] To better distinguish between the static panoramic image and the embedded live video, the panoramic image can also be displayed in black and white, while the live video is shown in color. In addition, recently updated image areas within the panorama can be displayed in color, while areas that were updated some time ago are shown in grayscale. In preparation, the panoramic image 2 is generated by the camera 1 automatically moving to predefined positions, as shown in Fig. 1 to Fig. 3 and 4, which are defined such that individual shots 3 between two neighboring positions overlap by approximately 10 to 30%. At each position, the camera 1 takes a static image (individual shot 3). In addition, the system saves the meta information of the camera 1 (horizontal and vertical alignment, zoom factor) for each individual shot 3.The individual images 3 are then combined into the entire panoramic image 2 using a known software algorithm, taking the meta information into account, and displayed to the user.

[0038] The display may be provided via any suitable display means, such as a screen, a touch-sensitive screen, a VR headset screen, an array of multiple screens, a window within a screen, a projector, or the like.

[0039] The generated panoramic image 2 is 2-dimensional and initially static, i.e., motionless. The invention offers the advantage of continuously updating the panoramic image 2 at the necessary positions or sections 6. The invention addresses the problem of determining which events trigger specific updates of the panoramic image 2 and how the updates are then carried out specifically and precisely.

[0040] Fig. 4 shows how a panoramic image 2 with a significantly larger angle of view is created from three exemplary individual images 3, each with a specific first angle of view. In this example, an airfield is captured, consisting of the airport floor, which represents terrain 7, the terrain edge 8, and the sky 9.

[0041] The panorama generation process is fully automated. During display, the panoramic image 2 according to Fig. 5 can be augmented with additional graphic overlays 10 to enable the user to better orient themselves in the displayed terrain (for example, by coloring areas where aircraft are parked or overlaying them with hatching). The graphic overlays can also include symbols and / or numbers for aircraft or flying objects in the sky 9, with the contents of these symbols / numbers being, for example, the radio registration number, flight altitude, or flight speed. In the following, reference is generally made to objects 11 that move within the field of view of the panoramic image 2.

[0042] Additionally, the panoramic image 2 can be provided with additional depth information to enable appropriate adjustment of the zoom factor and focus of camera 1. Especially with smaller objects (e.g., drones or birds), the autofocus of camera 1 may not function properly. If depth information about such objects is known, the focus and zoom factor of camera 1 can be adjusted according to this depth information, or at least the autofocus can be supported.

[0043] Further content of graphic overlays 10 that can be superimposed into the panoramic image 2 can be the additional depth information described above. This can be static information, such as the distance of certain parts of the landscape visible in the panoramic image 2, or

[0044] Surveillance information, for example, provided by a radar system (position of aircraft) or information about the size of visible objects generated by automatic image recognition. This type of depth information provides the operator with information about objects visible directly in panoramic image 2. Ideally, it is displayed spatially close to these objects and thus supports the operator in his work because he does not have to look at a separate screen from panoramic image 2 to obtain this information. The depth information is read in via suitable interfaces from corresponding data sources, such as rangefinders, radar systems, image recognition software (for object sizes). For static objects, such as mountains or buildings, this depth information can be permanently entered into the system. In the example of the “Remote Tower Application,” the operator is an air traffic controller.Other use cases can involve any type of user.

[0045] The alignment of camera 1 is carried out via input devices, for example by a simple "click" or "touch" within the panorama image 2. The camera 1, such as a PTZ camera, is then aligned vertically and horizontally exactly in this direction. If additional depth information has been stored, the zoom factor and the focus of the camera are adjusted accordingly based on the stored depth information in order to display the displayed image content precisely, e.g. with regard to sharpness. An alternative input device for aligning camera 1 is a sensor that determines the direction the operator is looking at the panorama 2, such as a camera that records the operator's face with downstream image recognition software that determines the alignment of the operator's eye axes.

[0046] Another option for determining the operator's viewing direction is VR glasses worn by the operator, whose sensors determine the viewing direction and transmit it to the system.

[0047] In addition, the orientation of the camera 1 can also be carried out using position data of objects 11, such as an aircraft, which are provided by a third-party sensor (e.g., transponder, radar, etc.). The PTZ video image can be displayed in the original resolution in a separate window 4 next to the panoramic image 2 (Fig. 6) – e.g., to provide even more information about the situation.

[0048] -, but in any case scaled directly in the panorama image 2. According to Fig. 6, this gives the user the impression that they are controlling the camera 1 via a live panorama, which makes the system even more intuitive to use and view. If a separate window 4 is provided, the video within it is generally enlarged, i.e. displayed unscaled in full image resolution, while the video inserted in the panorama image 2 is always scaled to the appropriate size in the panorama image 2. A selected section of the panorama image 2 can therefore be displayed larger to the operator, which means that the operator can recognize details better in this larger section than in the panorama image 2. An example of this is the contours of an aircraft fuselage: In the larger section, the operator can recognize whether the landing gear of this aircraft is extended or retracted better than in the panorama image 2. By integrating third-party sensors (e.g.Using an ADS-B transponder or radar, the panoramic image 2 can be augmented with additional real-time data from aircraft and other objects 11 to further increase the operator's situational awareness. In addition, the position data from the third-party sensor can also be used to control the PTZ cameras. Figure 6 shows an example of a combination 12 of an aircraft with an associated graphic overlay in the (live video) section 6.

[0049] Transponder and / or radar data can also be used to automatically control camera 1. Using such data, camera 1 can be automatically moved to the areas that are currently important to the operator. For example, camera 1 can be controlled so that its recording area captures the position of an aircraft, which position is determined using the aircraft's transponder data. This allows the panoramic image to be updated automatically and without operator intervention in the areas that are currently important to the operator.

[0050] The use of third-party sensors ensures that camera 1 can be aligned with the aircraft even if it is not yet visible in panoramic image 2. This makes it significantly easier for the operator to locate the aircraft as soon as it comes into view. In the embodiment shown in Figs. 5 and 6, some objects 11 are depicted larger and clearer than they are in real life, which also makes it easier for the operator to reliably identify these objects in panoramic image 2.

[0051] Two cameras 1 can also be present, which generate the panoramic image 2 step by step and then update it step by step. Although this increases the equipment complexity of the method and the system, it is then possible, for example, to insert current movements of two independent objects 1 1 within the angular range of the panoramic image 2 independently of one another as a video sequence into the panoramic image 2. Even if the sections 6 of both objects 1 1 overlap at a time, the invention ensures that the optically better of the two sections 6 in terms of, for example, contrast, brightness and zoom factor is displayed - and thus both moving objects 1 1 remain visible even at this particular time - while the other can be temporarily discarded (see below).

[0052] If the two objects 11 are flying objects, a temporary overlap of their trajectories in the panoramic image 2 (or even a proximity of both trajectories) does not necessarily indicate a collision or risk of collision, since the flying objects are only too close apart, for example in terms of their spatial depth from the perspective of the panoramic image 2. Whether and how large this real spatial distance, which is initially not visible in the two-dimensional panoramic image, is is then displayed, for example, via depth information graphically attached to the objects and / or a graphic overlay 10, so that the operator can always decide clearly and intuitively before, during and after the event whether to intervene in the flight process. A significant challenge is therefore the overlap of the sections 6 of two PTZ windows when both cameras 1 are aligned in approximately the same direction, so that the two image sections overlap.This can be relevant in that, in the worst case scenario—namely, when there is little contrast and brightness between an object 11 and the background, or when the camera's color settings are unfavorable—an object 11 is only seen by one camera 1 and not by the other. If the latter then covers the image captured by the first, the object 11 is completely invisible to the operator.

[0053] The invention solves this problem by applying the following method: After the static panoramic image 2 is generated by a camera 1, the panoramic image 2 is used as a reference image. Because the system knows the position of the new section 6 within the panoramic image 2, predetermined individual pixels, ranges of pixels, or all pixels in the PTZ live video image can be assigned to the individual reference pixels in the static panoramic image 2 and compared, for example, in terms of color. The comparison can also be made with regard to contrast, brightness, zoom factor, or combinations of these properties.

[0054] The system compares the majority of pixels between the static image and the live PTZ video image and adjusts the color settings (and / or contrast settings, brightness settings, etc.) of camera 1 so that the critical values ​​of the corresponding pixels are as identical as possible. This process is performed for all cameras 1 used, so that all cameras 1 deliver a color-identical video image (or static image). To perform this pixel comparison as accurately as possible, any offset caused by the different camera positions must be compensated for by the software. If two or more individual shots 3 overlap, the overlapping areas are blended semi-transparently. Software modules for the graphical implementation of blends of this type with individually adjustable parameters can be found in the state of the art.In addition, those areas that exhibit a significant deviation from the static reference image are further enhanced; e.g., the contrast is increased. This process prevents faintly visible objects from being displayed to the operator.

[0055] When assessing the risk when observing an object 11 (aircraft, drone, birds, etc.), the reference to the surroundings is always crucial. For this reason, it is necessary for the operator to be able to see not only the object 11 and its immediate surroundings, but also the landscape below the object 11. The system determines the terrain edge 8 on the horizon in the static panoramic image 2. The system then ensures that the zoom factor of the PTZ cameras is automatically adjusted so that both the object 11 and the terrain edge 8, including an adjustable vertical range (i.e. angular range) of the terrain 7 below, are visible in the live video image of the PTZ camera. This works with both automatic and manual tracking of a camera 1.In this way, the operator is able to determine the position of the object 1 1 in relation to the terrain 7 at any time and to make sensible decisions regarding airfield control.
