[0002] With the advancement of video security technology, video stream capture methods are no longer limited to cameras mounted on brackets or poles. A trend is emerging towards a wide range of capture devices, including handheld body cameras, brooch cameras, and AR glasses. Compared to fixed cameras, these devices are more susceptible to jitter during video capture, which can be significantly affected by human factors (such as the ups and downs of running). Watching this jittery video directly can cause the eye to constantly adjust focus and focal length due to the excessive jitter, making it difficult to see the image clearly, resulting in missing key information.

[0003] Traditional anti-shake technology is mostly based on physical improvements, eliminating slight physical shake by adding a balancing device to the video capture equipment. However, the problems with this method are: 1. It cannot eliminate the impact of large-scale shaking on video browsing; 2. Small video capture devices such as brooch cameras and AR glasses are not suitable for adding additional anti-shake devices. Summary of the Invention

[0028] The present application will be described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present application and are not intended to limit the present application. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions of the present application, not all of the components.

[0029] Figure 1 This is a flowchart of an image display method provided by an embodiment of the present application. This embodiment is applicable to scenarios where video jitter is eliminated. This method can be performed by an image display device provided by an embodiment of the present application. This device can be implemented using software and / or hardware and can be integrated into electronic devices.

[0030] like Figure 1 As shown, the image display method provided in the embodiment of the present application may include the following steps:

[0031] S110: Determine first position information of a target area in the image to be displayed being located in the image display area.

[0032] The image to be displayed refers to each frame of video image captured by a video capture device and to be played.

[0033] In the embodiment of the present application, the target area refers to the area in the video image where the target to be tracked is located. The image display area refers to the area used to display the video image screen during actual video playback. For example, Figure 2 This is a schematic diagram of the regional settings provided by an embodiment of the present application. Figure 2 As shown, the area enclosed by frame a is the entire display area. If the video is played on a television, the entire display area can be the entire screen display area of ​​the television. The area enclosed by frame b is the image display area. As will be understood, during actual playback, the video is displayed and played in the image display area. The area enclosed by frame c is the target area.

[0034] In an embodiment of the present application, the first position information refers to the position information of the target area relative to the image display area. The first position information can be expressed by the relative coordinates of the intersection of the diagonals of the target area in the image display area. For example, the coordinates are established with any point A in the image display area as the coordinate origin, and the coordinates (x, y) of the center point of the target area relative to the coordinate origin are calculated. Then, the first position information of the target area is A as the coordinate origin, and the coordinates of the center point are (x, y). The first position information can also be expressed by the relative coordinates of the four corner points of the target area in the image display area. For example, the coordinates are established with any point A in the image display area as the coordinate origin, and the coordinates of the four corner points of the target area relative to A are calculated to be (x1, y1), (x2, y2), (x3, y3) and (x4, y4). Then, the first position information of the target area is A as the coordinate origin, and the coordinates of the four corner points are (x1, y1), (x2, y2), (x3, y3) and (x4, y4). The first position information can also be expressed by the distance between the four sides of the target area and the four sides of the image display area, etc. It is understandable that the first position information corresponding to the same target area can be expressed in a variety of different ways.

[0035] It is understandable that due to the jitter of the picture, the position of the target area relative to the video image in each frame of the video image may be different, so for each frame of the video image, the first position information of the target area in the image display area must be determined so that the target area can be fixed in a certain position through subsequent movement.

[0036] S120: Determine third position information of the target area relative to the preset display point based on the first position information and the second position information of the image display area relative to the preset display point in the entire display area.

[0037] The preset display point is the position of the preset center point of the target area within the overall display area during actual video playback. It is understood that to eliminate the impact of image jitter on target tracking, this application translates the target area in each frame of video from its initial position to the preset display point to fix the viewing angle. The preset display point can be the center point of the overall display area or any other position within the overall display area.

[0038] In an embodiment of the present application, after determining a preset display point, the second position information of the image display area relative to the preset display point within the overall display area is calculated. In this embodiment, the image display area can be an area of ​​any size within the overall display area and can be configured according to user needs. The expression of the second position information corresponding to the image display area can be similar to the expression of the first position information. Similarly, the second position information corresponding to the image display area can be expressed in a variety of different ways.

[0039] In an embodiment of the present application, the third position information is determined based on the first and second position information. The third position information can be determined by calculating the coordinates in the first and second position information, or the third position information can be calculated based on the relative distance information in the first and second position information.

[0040] In this embodiment, determining the third position information of the target area relative to the preset display point based on the first position information and the second position information of the image display area relative to the preset display point in the entire display area includes:

[0041] The sum of the horizontal coordinates in the first position information and the horizontal coordinates in the second position information is used as the horizontal coordinate in the third position information, and the sum of the vertical coordinates in the first position information and the vertical coordinates in the second position information is used as the vertical coordinate in the third position information to determine the third position information.

[0042] For example, Figure 3 This is a schematic diagram of determining location information provided by an embodiment of the present application. Figure 3 As shown, a is the overall display area, b is the image display area, and c is the target area; point C is the center point of the target area, point B is any point in the image display area, and point A is the preset display point. First, a coordinate system is established with B as the coordinate origin. Assuming that the coordinates of point C in coordinate system B are (4, 4), the first position information of the target area can be expressed as the position where B is the coordinate origin and the center point coordinates are (4, 4). Then a coordinate system is established with the preset display point A as the coordinate origin. Assuming that the coordinates of point B in coordinate system A are (5, 4). At this point, it can be seen that with A as the coordinate origin, the coordinates of point C are (9, 8), so the third position information of the target area relative to the preset display point can be expressed as the position where the preset display point A is the coordinate origin and the center point coordinates are (9, 8).

[0043] S130: According to the third position information, translate the image display area, and display the image to be displayed in the image display area.

[0044] The translation of the image display area is to translate the target area in each frame of the video image from the initial position to the preset display point. Since the target area is located in the image display area, the image display area will also be translated accordingly.

[0045] After the image display device translates the target area of ​​each frame of video image from the initial position to the preset display point, the image display device displays and plays the frame of video image in the image display area.

[0046] The technical solution of this embodiment achieves the elimination of jitter in the video through the following method: determining the first position information of the target area in the image to be displayed in the image display area; based on the first position information and the second position information of the image display area relative to the preset display point in the overall display area, determining the third position information of the target area relative to the preset display point; based on the third position information, translating the image display area and displaying the image to be displayed in the image display area. The above technical solution eliminates the impact of image jitter on human vision without the need for additional jitter elimination devices during image acquisition, ensuring the smoothness of the image. The solution is simple and low-cost, which is beneficial for accurately tracking targets in the video.

[0047] Figure 4 This is a flowchart of an image display method provided by another embodiment of the present application. This embodiment is optimized based on the above embodiment.

[0048] like Figure 4 As shown, the image display method provided in the embodiment of the present application may include the following steps:

[0049] S210: Determine first position information of a target area in the image to be displayed being located in the image display area.

[0050] S220: Determine third position information of the target area relative to the preset display point based on the first position information and the second position information of the image display area relative to the preset display point in the entire display area.

[0051] In the embodiment of the present application, before determining the third position information of the target area relative to the preset display point based on the first position information and the second position information of the image display area relative to the preset display point in the overall display area, the method further includes:

[0052] The image display area is drawn in the overall display area; wherein the image display area is consistent with the area of ​​the overall display area reduced by four times, and the center point of the image display area coincides with the center point of the overall display area; the preset display point is the center point of the overall display area.

[0053] For example, Figure 5 As shown, Figure 5 This is a schematic diagram of the image display area setting provided by another embodiment of the present application. The area included in frame a is the overall display area, and the area included in frame b is the image display area. Under the technical solution of this embodiment, when starting the playback of a video stream, the video stream is first decoded and played at the most central position of the overall display area. The area ratio of the image display area to the overall display area is 1:4, avoiding poor display effects caused by too small scaling. The initial scaling ratio can be changed through settings according to user needs, but the default ratio of 1:4 ensures that the actual image display area will not be translated outside the overall display area.

[0054] S230: According to the third position information, translate the image display area, and display the image to be displayed in the image display area.

[0055] Figure 6 This is a schematic diagram of image display area translation provided by another embodiment of the present application. Figure 6 As shown, when drawing the image display area, the image display area is aligned with the area of ​​the overall display area reduced fourfold, and the center point of the image display area coincides with the center point of the overall display area. The center point of the overall display area is set as the preset display point. The image to the right of the arrow shows the image of the video frame after the target area is translated to the preset display point. As can be seen from the image, the target area is translated toward the lower left corner, and the image display area containing the target area is also translated toward the lower left corner.

[0056] S240: Determine a translation area reached by the image display area during translation within a first preset time.

[0057] The first preset time can be set according to user needs. The translation area to which the image display area is translated refers to the area covered by the maximum translation when the image display area is translated up, down, left, or right due to video image jitter. After setting the first preset time, this embodiment records the amount of translation of the image display area within the first preset time, and calculates the translation area based on the translation amount.

[0058] Figure 7 This is a schematic diagram of an enlarged region provided by another embodiment of the present application. Figure 7As shown, p1, p2, and p3 are the translations of the image display area recorded within the first preset time. The area enclosed by frame m is the translation area covered by the image display area during the first preset time. Each time the image display area translates within the first preset time, the coordinates of the area reached by the image display area after translation within the overall display area are recorded. After the image display area translates multiple times within the first preset time, the coordinates of all areas reached by the image display area after translation within the overall display area are recorded. The entire area reached by the image display area, i.e., the translation area, is determined based on the coordinates of the smallest horizontal coordinate, the largest horizontal coordinate, the smallest vertical coordinate, and the largest vertical coordinate among all the areas.

[0059] S250: Enlarge the translation area according to the relative size of the translation area and the overall display area.

[0060] The translation region may be enlarged according to the size of the overall display region. For example, the horizontal side of the translation region may be enlarged to 90% of the horizontal length of the overall display region. Alternatively, the vertical side of the translation region may be enlarged to 90% of the vertical length of the overall display region. Alternatively, the region may be enlarged at any magnification factor, which is not limited in this embodiment.

[0061] S260: Enlarge the image display area according to the magnification factor of the translation area.

[0062] S270: If the enlarged translation region is not completely within the overall display region, translate the enlarged translation region and the enlarged image display region so that the enlarged translation region is completely within the overall display region.

[0063] For example, Figure 8 This is a schematic diagram of an image display method provided by another embodiment of the present application. Figure 8 As shown, the left side of the enlarged translation region extends beyond the overall display area. In this case, translation compensation is required after enlarging the translation region. After compensation, the enlarged translation region is completely within the overall display area. For example, the difference between the coordinates of the center point of the translation region and the coordinates of the center point of the overall display area can be determined and used as the translation compensation to translate the translation region so that the center point of the translation region is aligned with the center point of the overall display area, ensuring that the entire translation region is within the overall display area.

[0064] In the embodiment of the present application, after the magnification adjustment using the above method, the main viewing angle is no longer at the center point of the entire display area, but is still locked at a fixed position in the area, which does not affect the observation effect of the human eye, and the overall dynamic display effect is closer to the center position. This method not only solves the problem that the actual image display area accounts for too small a proportion of the overall display area, which is not conducive to observation, but also ensures that the image display area does not shift outside the entire display area. When the image suddenly shakes and causes the magnified image display area to shift outside the entire display area, the magnification factor is immediately reduced to enable full display, and the magnification factor is recalculated, and the above action is repeated.

[0065] In this embodiment, after translating the magnified translation area and the image display area, the method further includes:

[0066] translating a preset display point in the overall display area according to the magnified translation area and the translation distance of the image display area;

[0067] For a new image to be displayed, the steps of determining the third position information of the target area relative to the preset display point after translation based on the first position information and the second position information of the preset display point after translation of the image display area relative to the overall display area, and displaying the new image to be displayed are performed.

[0068] It can be understood that in order to address the problem that the enlarged translation area may exceed the overall display area, the enlarged translation area and the image display area are translated so that they are within the overall display area, which will cause the target area to deviate from the original preset display point. Therefore, the preset display point must be translated accordingly according to the translation distance of the enlarged translation area and the image display area.

[0069] In the embodiment of the present application, after the image display area is enlarged and translated, the first position information of the target area within the image display area changes. Simultaneously, due to the translation of the preset display point, the second position information of the image display area relative to the preset display point within the overall display area also changes. Therefore, after the translation area and the image display area are enlarged and translated, and the preset display point is translated, the image display device re-executes steps 210-230 for the new image to be displayed based on the translated preset display point.

[0070] The technical solution of this embodiment achieves the enlargement of the image display area by the following method: determining the translation area reached by the image display area during translation within a first preset time; enlarging the translation area based on the relative size of the translation area and the overall display area; enlarging the image display area based on the magnification factor of the translation area; if the enlarged translation area is not completely within the overall display area, then translating the enlarged translation area and the enlarged image display area so that the enlarged translation area is completely within the overall display area. The above technical solution not only enlarges the playback image but also ensures that the image does not exceed the screen range, thereby improving the user's video viewing experience and allowing for more accurate tracking of targets in the video image.

[0071] Figure 9 This is a flowchart of an image display method provided by another embodiment of the present application. This embodiment is optimized based on the above embodiment.

[0072] like Figure 9 As shown, the image display method provided in the embodiment of the present application may include the following steps:

[0073] S310: Perform feature detection on at least two frames of historical display images within a second preset time to determine feature information.

[0074] The second preset time refers to a period of time during the video playback duration, which can be set according to actual needs. For example, if a video duration is 10 minutes, the second preset time can be set to 2 minutes.

[0075] In the embodiment of the present application, the feature information may include the number of people or vehicles in the image, etc. The feature detection method may be Harris algorithm, FAST algorithm, etc., and the present embodiment does not limit the algorithm used for feature detection.

[0076] This embodiment uses a feature detection algorithm to detect feature information contained in at least two frames of historical display images contained in the second preset time.

[0077] S320: Match feature information in at least two frames of historical display images, and use consistent feature information as target feature information.

[0078] For example, for example, the feature information in the first frame of the historical display image is F1, F2, and F3, the feature information in the second frame of the historical display image is F2, F5, and F6, and the feature information in the third frame of the historical display image is F2, then after matching, the consistent feature information in the three frames of the historical display image is F2, then F2 is used as the target feature information, and the perspective of F2 is used as the fixed target in the subsequent process of eliminating jitter and fixing the perspective.

[0079] The above-mentioned target feature information is selected by the system, but the target feature information may not be the feature that the user actually wants to focus on, or even if it is the feature that the user actually wants to focus on at the beginning, as the shooting picture changes, the feature will become incorrect due to various scene factors. Therefore, this embodiment provides two revision modes: frame selection mode and scene analysis mode, which are used to determine the target feature information according to user needs.

[0080] In this embodiment, it is determined that the target area in the image to be displayed is located before the first position information in the image display area, and the method further includes:

[0081] determining a feature area according to a selection operation performed by a user on a historical display image or a historical display video;

[0082] Feature information in the feature area is determined as target feature information.

[0083] The selection operation refers to a user selecting an area in the played video stream where the feature information that the user wants to focus on is located by touching or writing with a pen.

[0084] In an embodiment of the present application, the image display device identifies feature information within the framed area according to the user's operation and the image detection algorithm, and uses the feature information as target feature information.

[0085] In this embodiment, the user can perform a selection operation in a static video picture, or can directly perform a selection operation in a shaking video picture being played.

[0086] In this embodiment, it is determined that the target area in the image to be displayed is located before the first position information in the image display area, and the method further includes:

[0087] Determine the target object according to the scene mode selected by the user;

[0088] Target object detection is performed on the historical display image, and feature information of the target object is determined as target feature information.

[0089] Among them, the scene mode can be a human body tracking mode, a face tracking mode, a vehicle tracking mode, etc.

[0090] In the embodiment of the present application, if the user selects the human body tracking mode, the target object is a human body in the video screen; if the user selects the vehicle tracking mode, the target object is a vehicle in the video screen.

[0091] In an embodiment of the present application, the image display device uses a correlation algorithm to detect a target object from a historical real-life image, and uses feature information of the target object as target feature information.

[0092] For example, taking the human body tracking mode as an example, when the user selects the human body tracking mode, the system analyzes the human body information in the picture according to the human body analysis algorithm, extracts human body feature data, and takes a snapshot. While displaying the video screen, the extracted human body image is also displayed to the user, and the user selects the human body target to be tracked and uses the target feature information as the target. After the user selects the human body to be tracked, the system saves the feature information of the human body. When each subsequent frame is decoded and displayed, the human body information in the picture is first analyzed. When a human body feature image with a high similarity is matched, the human body frame area appearing in the picture is used as the target area and the subsequent de-shaking step is performed.

[0093] S330: Use the area in the image to be displayed that corresponds to the feature information that matches the target feature information as the target area.

[0094] For example, if the target feature information is F2, and the image to be displayed is subjected to feature detection and contains feature information of F1, F2, F4, and F6, then the area where F2 is located in the image to be displayed is used as the target area.

[0095] S340: Determine first position information of the target area in the image to be displayed being located in the image display area.

[0096] S350: Determine third position information of the target area relative to the preset display point based on the first position information and the second position information of the image display area relative to the preset display point in the entire display area.

[0097] S360: According to the third position information, translate the image display area and display the image to be displayed in the image display area.

[0098] This embodiment also provides a display method for multi-target tracking. Figure 10 As shown, Figure 10This is a schematic diagram of a multi-target tracking display provided by another embodiment of the present application. When the user selects multiple targets from the screen to be tracked simultaneously, the image display area performs simulated split-screen processing according to the number of selected targets. The specific method of display is: 1. First, the corresponding algorithm parses the current video stream, counts the structured data and displays the frames for the multiple identified targets; 2. The user selects the target to be tracked and selects the corresponding frame; 3. The system saves the selected human feature information and assigns a number to each target. At the same time, according to the number of selected targets, the system splits the screen on the entire display area, and copies multiple copies of the original stream to display at a specific position on each split screen. The target number is the same as the split screen number; 4. When each frame is decoded and displayed, the algorithm first parses the video stream, matches the target with a highly similar feature value, and uses the target frame as the target area; 5. In each split screen, the step of eliminating jitter is performed on the target area.

[0099] The technical solution provided in this embodiment can provide users with multiple target tracking modes and target selection methods, so that users can determine the target they need to focus on according to actual needs, and fix the target's perspective as the main perspective to improve the user's viewing experience.
