The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

Referring to fig. 2, in one embodiment, a monitoring image displaying method for an intelligent traffic system is provided. The embodiment is mainly illustrated by applying the method to the monitoring terminal 12 in fig. 1. Referring to fig. 2, the method for displaying the monitoring image specifically includes steps S201 to S204, which are specifically as follows:

s201, acquiring and displaying a three-dimensional columnar image to be processed, wherein the three-dimensional columnar image is a target monitoring image after bending processing, and the target monitoring image is an image acquired by the front-end camera.

The target monitoring image can be an image collected by a front-end camera 11 preset at any position, and the image can be an image obtained through a photographing mode or an image extracted from a monitoring video obtained through a video recording mode; the arbitrary location may be any location where a surrounding scene needs to be monitored, such as a train station, a highway, a street, etc. It can be understood that the front-end camera 11 can acquire a plurality of images, but only one image can be displayed in a three-dimensional column shape, and the image is a target monitoring image. The selection and determination of the target monitoring image can be selected and determined by a worker with a monitoring image display requirement in some way, for example: (1) the monitoring terminal 12 displays thumbnails of a plurality of images through an interactive interface, and a worker can select to submit any one of the images, so that the selected image is the target monitoring image; (2) the monitoring terminal 12 performs image recognition on the image or video sent by the front-end camera 11 through a preset image recognition algorithm, and if a certain frame of image is recognized to include a preset target object or behavior, the image can be determined as a target monitoring image, for example, an image including prohibited articles or a video including dangerous behaviors is recognized; (3) the monitoring terminal 12 extracts and displays the images or videos sent by the front-end camera 11 at regular time based on an image timing display rule preset by a worker, wherein the images extracted at a target time point are target monitoring images; (4) the interactive interface of the monitoring terminal 12 displays a plurality of virtual buttons, each virtual button corresponds to one front-end camera 11, the staff triggers the virtual button corresponding to one of the front-end cameras 11, that is, submits the image acquired by the front-end camera 11 to the monitoring terminal 12 as a target monitoring image, and if the image acquired by the front-end camera 11 is a video, the monitoring terminal 12 can perform random frame extraction, frame extraction identification and frame extraction at regular time on the video to determine the target monitoring image. It should be noted that, although the embodiment only exemplifies four target monitoring image obtaining manners, it is not excluded that in other embodiments, the target monitoring image may be obtained by superimposing, replacing, and the like the four manners. The embodiment of the present application does not limit the specific acquiring method of the target monitoring image, but details of one of the acquiring methods of the target monitoring image will be described below.

Specifically, after the monitoring terminal 12 obtains the target monitoring image, the target monitoring image may be subjected to bending processing of the fitting model based on the preset three-dimensional columnar model, so that the finally processed target monitoring image may be shaped as a hollow cylinder, that is, a hollow cylinder without top surfaces of an upper cylinder and a lower cylinder. It can be understood that, in the processed three-dimensional cylindrical image, the outer side surface of the cylinder should be displayed as a picture in the target monitoring image, and the inner side surface of the cylinder can display a pure surface with any preset ground color, such as gray, black, white, and the like. After the monitoring terminal 12 acquires and displays the three-dimensional columnar image to the worker through the interaction interface, the monitoring terminal can wait for the trigger instruction of the worker, so that the three-dimensional columnar image is processed continuously according to the corresponding trigger instruction, and the next omnibearing display of the target monitoring image is realized.

It should be noted that, the user/worker referred to in the embodiment of the present application may be a developer of the monitoring terminal 12, or may be an insider of the public security system.

In one embodiment, this step includes: acquiring at least one monitoring image through the front-end camera to obtain a thumbnail image corresponding to the at least one monitoring image; displaying a thumbnail image corresponding to the at least one monitoring image; determining a target monitoring image in the at least one monitoring image in response to a user selected trigger event for the thumbnail image; based on a preset three-dimensional columnar display model, bending the target monitoring image to obtain a three-dimensional columnar image; and displaying the three-dimensional columnar image.

The thumbnail image is an image obtained by reducing the monitoring image according to a certain proportion, and the image content and the content size of the thumbnail image are consistent and inconsistent; the monitoring image refers to an image collected by the front-end camera 11.

The selection trigger event refers to an image selection instruction submitted by a user through the monitoring terminal 12, a mouse or a touch pen at a certain moment in the terminal interface, and the operation may be a click operation, a double click operation or a long press operation. For example, one or more images are displayed on the interactive interface of the monitoring terminal 12, and when a user clicks a certain image, an image selection instruction for the image is submitted to the monitoring terminal 12, and this operation process is a selected trigger event for the image.

The three-dimensional columnar display model is a virtual model presenting a three-dimensional cylindrical shape, and can be used for displaying a three-dimensional columnar image.

Specifically, the monitoring terminal 12 may obtain one or more monitoring images through the pre-connected front-end camera 11, and scale down the obtained monitoring images to obtain corresponding thumbnail images. The purpose of the monitoring terminal 12 obtaining the thumbnail image corresponding to the monitoring image is to promote the interactive interface of the monitoring terminal 12 to display more monitoring images to the maximum, and avoid the frequent operation of the user to refer to each monitoring image.

For example, the interactive interface of the monitoring terminal 12 may display one monitoring image, but may simultaneously display thumbnails of 6 monitoring images.

More specifically, after the monitoring terminal 12 acquires and displays the thumbnail image corresponding to the monitoring image, it may detect and respond to a trigger event selected by the user for a certain thumbnail image, determine a target monitoring image selected and submitted by the user, and then perform bending processing on the target monitoring image by using the three-dimensional columnar display model to acquire the three-dimensional columnar image. It can be understood that, although how to perform the bending processing on the target monitoring image to obtain the three-dimensional cylindrical image is not described in detail in this embodiment, how to perform the unfolding processing on the three-dimensional cylindrical image to obtain the corresponding planar rectangular image will be described in detail below in the monitoring image displaying method provided by the embodiment of the present application. That is, the process from the target monitoring image to the three-dimensional columnar image is actually the reverse process from the three-dimensional columnar image to the planar rectangular image, and the processing steps are the same, but the execution sequence is reverse. The application provides and changes target monitoring image into three-dimensional column image, changes the three-dimensional column image into plane rectangle image again, and aim at provides the intermediate effect of image display for the user, helps the user more conveniently, look over monitoring image more all-roundly, improves current image display mode because of there being image display mode single, and lead to the poor problem of monitoring image display effect.

S202, responding to an image unfolding trigger event of a user for the three-dimensional columnar image, acquiring an image unfolding position determined by the user, after obtaining a three-dimensional columnar coordinate point on the image unfolding position, splitting a coordinate point distance between the three-dimensional columnar coordinate point and a preset unfolding plane coordinate point in an equal proportion to obtain an unfolding position coordinate, and carrying out plane unfolding processing on the three-dimensional columnar image through the unfolding position coordinate to obtain a plane rectangular image; and the unfolding plane coordinate point is determined according to the length, the width and the height of the three-dimensional columnar image and is a coordinate point which is on the same circular surface with the three-dimensional columnar coordinate point.

The image unfolding position refers to a position where the image is split, that is, the image splitting line shown in fig. 3 described above.

The three-dimensional cylindrical coordinate point and the expansion plane coordinate point are coordinate points determined based on a preset image coordinate system. For example, a three-dimensional cylindrical coordinate point refers to a coordinate point in an image coordinate system at a specified pixel location in a three-dimensional cylindrical image; for example, the developed planar coordinate point is a coordinate point in the image coordinate system based on a pixel position in the planar rectangular image corresponding to a specified pixel position in the three-dimensional columnar image after the three-dimensional columnar image is developed into the planar rectangular image.

The coordinate point distance refers to a distance value between any two coordinate positions. For example, (x, y, z) of the three-dimensional cylindrical coordinate point in the preset image coordinate system is (0, 2, 5), and assuming that (x, y, z) of the unfolded plane coordinate point after the image is unfolded is (-6, -2, 5), the corresponding coordinate point distance is about 7.

Specifically, after the monitoring terminal 12 acquires and displays the three-dimensional cylindrical image corresponding to the target monitoring image, it may receive an image expansion triggering instruction of the user for the three-dimensional cylindrical image through its interactive interface, and in response to the instruction, determine a coordinate point of the three-dimensional cylindrical image in a preset image coordinate system, that is, a three-dimensional cylindrical coordinate point, and perform plane expansion processing on the three-dimensional cylindrical image based on a coordinate point distance between the three-dimensional cylindrical coordinate point and a preset expansion plane coordinate point, so as to acquire a plane rectangular image obtained after the three-dimensional cylindrical image is expanded. It can be understood that the unfolding plane coordinate point referred to in this embodiment is a preset unfolding plane coordinate point, and the coordinate point may be a preset fixed coordinate point, or a relative coordinate point estimated after the unfolding according to the image dimensions such as the length, the width, and the like of the three-dimensional columnar image. The image expansion step in the present embodiment will be described in detail below, and reference may be made to fig. 3 for an expansion flow of the three-dimensional columnar image.

In one embodiment, this step includes: responding to an image expansion triggering event of a user aiming at the three-dimensional columnar image, and determining the coordinates of a target point to be split in the three-dimensional columnar image; the target point coordinate is one of the coordinates of the end points of the two lines on the split line corresponding to the image unfolding position; determining a coordinate point distance between the three-dimensional cylindrical coordinate point and the unfolding plane coordinate point according to the coordinates of the target point, wherein the unfolding plane coordinate point is a preset unfolding plane coordinate point; determining the expansion position coordinates of the three-dimensional columnar image according to the coordinate point distance and the preset image expansion times; the image expansion times are greater than or equal to two; and carrying out plane expansion processing on the three-dimensional columnar image based on the expansion position coordinates to obtain a plane rectangular image.

The coordinates of the target point are coordinates of a position to be split in the three-dimensional columnar image, for example, one of line end coordinates of a split line of the image shown in fig. 3.

Specifically, after detecting an image expansion triggering instruction of the user for the three-dimensional columnar image, the monitoring terminal 12 may first determine coordinates of a target point in the three-dimensional columnar image, and the determining step may be set according to actual application requirements, for example: (1) determining according to the image splitting position triggered and selected by the user on the three-dimensional columnar image; (2) determined according to a default image splitting position, such as an image centering position and the like; (3) the position between two target objects (e.g., two persons) such as a background image portion without a real object is determined according to the image content recognition result. It should be understood that, although the present embodiment exemplifies the determination manners of the coordinates of the three target points, it is not excluded that the three manners may be combined, superimposed, split, and the like in other embodiments, and the specific determination manner of the coordinates of the target points may be determined according to the actual application requirements.

More specifically, after the monitor terminal 12 determines the coordinates of the target point in the three-dimensional cylindrical image, the coordinate point distance between the three-dimensional cylindrical coordinate point and the unfolding plane coordinate point may be further analytically determined. The expansion plane coordinate point described in the foregoing embodiment may be a preset expansion plane coordinate point, and the coordinate point may be a preset fixed coordinate point, or a relative coordinate point after expansion may be estimated according to the image dimensions such as the length, the width, and the like of the three-dimensional columnar image. Therefore, the monitoring terminal 12 may obtain a coordinate point distance between the three-dimensional cylindrical coordinate point and the unfolding plane coordinate point after determining the unfolding plane coordinate point corresponding to the target point coordinate, that is, the three-dimensional cylindrical coordinate point at this time is the target point coordinate.

Further, after the monitoring terminal 12 determines the coordinate point distance between the coordinate point of the target point and the coordinate point of the expansion plane, the expansion position coordinate of the three-dimensional columnar image existing on the straight line of the distance corresponding to the coordinate line distance in the expansion process can be determined based on the preset image expansion times, and the expansion position coordinate is the coordinate point to be overlapped with the coordinate point of the target point in the image expansion process. Specifically, referring to fig. 4, a schematic diagram of a change from the coordinates "a" of the target point to the coordinates "a" of the unfolding plane in one embodiment is shown. It should be noted that the circular area shown in fig. 4 (a) is one of the circular top surfaces of the three-dimensional histogram, i.e., the top surface of the three-dimensional histogram shown on the left side in fig. 3. Further, although the present embodiment has simply explained three ways of determining the coordinates of the target point, specific target point coordinate determining step, coordinate point distance determining step, and deployment position coordinate determining step will be explained in detail below.

In one embodiment, the step of determining coordinates of a target point to be split in the three-dimensional columnar image in response to a user image expansion trigger event for the three-dimensional columnar image includes: responding to an image expansion triggering event of the three-dimensional columnar image by the user, and acquiring an image expansion position determined by the user; if the image unfolding position is a default position, determining the coordinates of the line end points on a preset splitting line in the three-dimensional columnar image as the coordinates of target points to be split in the three-dimensional columnar image; and if the image unfolding position is a calibration position, determining the coordinates of the line end points on a calibration splitting line determined by a user in the three-dimensional columnar image as the coordinates of target points to be split in the three-dimensional columnar image.

Specifically, the monitoring terminal 12 may have an interactive interface through which the three-dimensional columnar image is displayed, and after the user refers to the image and submits the image expansion triggering instruction for the three-dimensional columnar image through the interactive interface, the monitoring terminal 12 may respond to the image expansion triggering event corresponding to the image expansion triggering instruction, and further obtain the image expansion position determined and submitted by the user through the interactive interface.

Further, for the acquisition mode of the image expansion position, at least two virtual buttons are displayed on the interactive interface, and each button corresponds to one optional position, including a "default position" and a "calibration position". The user triggers a certain button, that is, determines and submits the image expansion position corresponding to the button to the monitoring terminal 12, and the button triggering mode may be click triggering, double-click triggering, long-press triggering, and the like.

More specifically, if the virtual button triggered by the user is the "default position", the monitoring terminal 12 may determine that a line end coordinate on a preset splitting line in the three-dimensional columnar image is a target point coordinate; if the virtual button triggered by the user is the "calibration position", the monitoring terminal 12 may determine that the line end point coordinates on the calibration splitting line determined by the user in the three-dimensional columnar image are the target point coordinates. Fig. 5 is a schematic interface diagram of the image expansion position determination step described in this embodiment. It should be noted that, when the virtual button triggered by the user is "calibration position", the monitoring terminal 12 provides a selection cursor, the selection cursor is displayed through an interactive interface, the displayed cursor may be in a split selection line for the three-dimensional columnar image, that is, as shown by a cursor line in fig. 5, four virtual buttons "up", "down", "left" and "right" in fig. 5 are provided for the user to adjust the position of the cursor line.

In one embodiment, the step of determining a coordinate point distance between the three-dimensional cylindrical coordinate point and the unfolding plane coordinate point according to the target point coordinates comprises: determining the coordinates of the target point as the three-dimensional columnar coordinate point; determining a cylindrical circular plane where the three-dimensional cylindrical coordinate point and the unfolding plane coordinate point are located; and calculating the distance value between the three-dimensional columnar coordinate point and the coordinate point of the expansion plane based on the columnar circular plane to obtain the coordinate point distance.

Specifically, before the monitoring terminal 12 determines the coordinate point distance between the three-dimensional cylindrical coordinate point and the unfolding plane coordinate point, the target point coordinate may be regarded as the three-dimensional cylindrical coordinate point as described in the above embodiment, and then the cylindrical circular plane where the three-dimensional cylindrical coordinate point and the unfolding plane coordinate point are located is first determined as the target plane. It will be appreciated that since the predetermined image coordinate system is a three-dimensional coordinate system, three-dimensional cylindrical images may have three planes in the coordinate system, namely two circular planes (a circular top plane and a circular bottom plane) formed by the edges of the images, and cylindrical side planes. Therefore, the three-dimensional cylindrical coordinate point and the unfolding plane coordinate point may exist in a plurality of planes at the same time, and in order to determine the three-dimensional cylindrical coordinate point and the unfolding plane, and the coordinate point distance between the coordinate points, it is necessary to first determine any circular plane in which the two coordinate points are located, as a cylindrical circular plane, and the coordinate point distance determined based on the cylindrical circular plane is the coordinate point distance required by the embodiment.

In one embodiment, the step of determining the coordinates of the expansion position of the three-dimensional columnar image according to the coordinate point distance and the preset image expansion times includes: based on preset image expansion times, carrying out equal-proportion splitting processing on the coordinate point distance to obtain at least one split point coordinate; determining the coordinates of the at least one splitting point as first unfolding position coordinates of the target point; acquiring a second unfolding position coordinate of each intermediate point coordinate based on the first unfolding position coordinate of the target point coordinate; the second unfolding position coordinate is a splitting point coordinate corresponding to the intermediate point coordinate; and determining the first unfolding position coordinate and the second unfolding position coordinate as the unfolding position coordinate of the three-dimensional columnar image.

The middle point coordinates may be point coordinates that are located on a circular top surface and are equidistantly disposed on a boundary of the top surface in the three-dimensional cylindrical image, and are located on the same circular top surface as the target point coordinates, that is, as shown in (b) of fig. 4, only the middle point coordinates of the left half of the top surface of the three-dimensional cylindrical image are shown, and the operation manner of the middle point coordinates of the right half is consistent with that of the left half, so that the right half image has been omitted.

Specifically, after the monitoring terminal 12 determines the coordinate point distance between the three-dimensional cylindrical coordinate point and the unfolding plane coordinate point according to the target point coordinates, the coordinate point distance may be split in equal proportion based on the preset image unfolding times to obtain at least one splitting point coordinate.

For example, the current coordinate point distance is "5", and if the preset image expansion frequency is "2", the split point coordinate number is "1"; if the preset image expansion times are 3, the number of the split point coordinates is 2, and so on. It is understood that, in order to improve the image expansion efficiency, although the number of times of image expansion may be set to "1", the image expansion quality will be affected therewith, resulting in poor image expansion effect. Therefore, the application proposes that the preset image expansion times are more than or equal to 2', so as to obtain at least one splitting point coordinate. Although the simulation approximation degree is only about 70% by the image expansion method, the difference is almost negligible for the user because the image expansion process is very short.

More specifically, after the monitoring terminal 12 obtains the coordinates of at least one splitting point, the coordinates of the at least one splitting point can be used as the coordinates of a first unfolding position corresponding to the coordinates of the target point, where the coordinates of the first unfolding position are the coordinates of a node of a movement path of the coordinates of the target point, that is, the coordinates of the target point need to be overlapped with the coordinates of the first unfolding position in the process of unfolding the image.

Further, after the monitoring terminal 12 determines the first unfolding position coordinate, the split point coordinate corresponding to each intermediate point coordinate may be obtained based on the same proportion as the second unfolding position coordinate, and finally the unfolding position coordinate of the three-dimensional columnar image is obtained.

In one embodiment, the step of performing plane expansion processing on the three-dimensional columnar image based on the coordinates of the expansion position to obtain a planar rectangular image includes: determining a middle point coordinate corresponding to a target point coordinate to be split in the three-dimensional columnar image; moving the target coordinate point based on the first unfolding position coordinate, and sequentially moving the intermediate point coordinate based on the second unfolding position coordinate to perform plane unfolding processing on the three-dimensional columnar image until the target coordinate point is overlapped with the unfolding plane coordinate point, wherein a straight line formed by connecting the target coordinate point with the intermediate point coordinate is vertical to a preset coordinate axis; and determining the three-dimensional columnar image after the plane expansion processing as the plane rectangular image.

Specifically, the present embodiment will use one of the circular top surfaces of the three-dimensional cylindrical image as the viewing angle, and will describe in detail how the coordinates of the target point and the intermediate point existing in the top surface move, so that the three-dimensional cylindrical image can be expanded into a planar rectangular image, as shown in fig. 4. The diagram (b) in fig. 4 indicates 4 intermediate point coordinates "a, b, c, d" respectively, and a target point coordinate "a" to be split, the first expansion position coordinates of the target point coordinate "a" are 2, respectively, "a'" and "a", and the second expansion position coordinates of the intermediate point coordinates "a, b, c, d" are not shown in fig. 4, but may refer to the setting value of the first expansion position coordinates.

For example, in the image coordinate system shown in fig. 4, the horizontal axis is the positive X-axis rightward, the vertical axis is the positive Z-axis upward, the radius of the circular top surface in the three-dimensional columnar image is "R", the perimeter of the circular top surface is "2 × PI × R", the initial coordinate value of the target point coordinate "a" is (0, R, y), the coordinate value of the unfolding plane coordinate point "a × is (-PI × R, -R, y), and the initial coordinate value (X, Z, y) of the 4 intermediate point coordinates" a, b, c, d "is in an equal proportion range from 0 to (-R), the Z-axis value range is in an equal proportion range from R to (-R), and the y-axes have the same value. If the three-dimensional columnar image is expanded 3 times, and the coordinate point distances between (0, R, y) and (-PI x R, -R, y) are subjected to equal proportion splitting processing, the coordinate values of the first expansion position coordinates "a '" and "a'" are ((-PI x R)/3, R-2R/3, y), (((-PI x R)/3 x 2, -R +2R/3, y), respectively, the second expansion position coordinates can be changed in equal proportion based on the first expansion position coordinates, that is, the corresponding relationship between the second expansion position coordinates and the first expansion position coordinates is equal to the corresponding relationship between the target point coordinates and the expansion plane coordinate points, the monitoring terminal 12 only needs to sequentially move the target coordinate points based on the first expansion position coordinates and sequentially move each intermediate point coordinate based on the second expansion position coordinates, the three-dimensional columnar image can be unfolded to a planar state, and a planar rectangular image is obtained. And the final plane rectangular image shows a state that a straight line formed by connecting the target coordinate point 'A' and the expansion plane coordinate point 'A' is overlapped and the target coordinate point 'A' and the intermediate point coordinates 'a, b, c and d' is vertical to the Z axis.

It should be noted that, since the embodiment only shows the expansion of one circular top surface, the Y-axis coordinate thereof is fixed and unchanged, and each coordinate on the Y-axis can be moved correspondingly according to the above, the specific coordinate value of the Y-axis is not specified in the embodiment.
