The application scenario of the embodiment of the present application is not limited thereto.
Based on this, the embodiment of the application provides a target tracking method, a target tracking device, an electronic device and a storage medium.
As shown in fig. 1, a target tracking method provided in an embodiment of the present application may include:
step S101: the current position of the tracking target is determined, and road network data including the current position is determined.
The method includes the steps that cameras are usually arranged on two sides of a road to monitor road conditions, the cameras can include position information of the cameras, the position information of the cameras can include geographic positions where the cameras are located and angles of videos shot by the cameras, and therefore in one possible implementation mode, the current position of a tracked target is determined, and the current position of the tracked target can be determined by the position of the camera shooting the tracked target; in another possible embodiment, the current position of the tracking target may be determined directly through a monitoring screen where the tracking target is currently located, for example, through a road identifier or a building identifier existing in the monitoring screen.
The road network data may be traffic road data, traffic junction data, or traffic network data formed by a plurality of roads, such as main roads, auxiliary roads, branch roads, and branch roads. The embodiment of the application does not limit the data form and the data type specifically contained in the road network data, the road network data can be acquired by a road network data supplier, or by downloading on the internet or from an electronic map, and the embodiment of the application does not limit the acquisition mode of the road network data. In addition, for different requirements, the road network data may be acquired in a city, a province, or a nationwide area including the current position of the tracking target, which is not limited in the embodiment of the present application, and the road network data including the current position of the tracking target is acquired to provide a basis for predicting a driving road to be passed by the tracking target.
Step S102: and predicting the driving road to be passed by the tracking target according to the road network data and the current position.
After the current position of the tracking target and the road network data including the current position are obtained, a driving road to be passed by the tracking target can be predicted according to the road network data and the current position. In one possible embodiment, the predicting a driving road to be passed by the tracking target according to the road network data and the current position comprises:
according to the road network data, predicting a driving road which is to be passed by a tracking target along a target driving direction by taking a current position as a starting point, wherein the target driving direction comprises at least one of the following: forward direction, reverse direction, left direction, right direction.
For example, the current position of the tracking target is marked in the road network data, and the driving road which the tracking target may pass through along the target driving direction is determined by taking the current position of the tracking target as a starting point. For example: judging that the current position of the tracking target is on a straight road through road network data, wherein the target driving direction may include a forward driving direction and/or a backward driving direction, and the driving road through which the tracking target passes may be a forward driving road and/or a backward driving road; for another example, if it is determined that the current position of the tracking target is at an intersection through the road network data, the target driving direction may include at least one of a forward driving direction, a backward driving direction, a leftward driving direction, and a rightward driving direction, and therefore, the driving road on which the tracking target is to pass may be any one of a forward driving road, a backward driving road, a leftward driving road, and a rightward driving road, which is not limited in this application.
Step S103: and predicting a camera which is about to pass by the tracking target on the driving road.
After the traveling road of the tracking target is predicted, in order to further realize the tracking of the tracking target, a camera through which the tracking target will pass on the traveling road may be predicted. The embodiment of the present application does not limit the specific implementation of the camera that predicts the passing of the tracking target on the driving road. In a possible implementation manner, the preset number of cameras on the driving road of the tracked target can be determined as the cameras through which the tracked target will pass on the driving road, and by determining the preset number of cameras as the cameras through which the tracked target will pass on the driving road, the problem that the tracked target shot when the number of cameras is small is not clear or the shooting time is short can be avoided, and the influence on the tracking efficiency of the tracked target when the number of cameras is too large can be reduced.
For example, if the driving road of the tracking target only has one straight road, it may be determined that the preset number of cameras on the straight road are the cameras that the tracking target will pass through on the driving road; if the driving road for tracking the target comprises a straight road and a left-turn road, at least one camera on the straight road and at least one camera on the left-turn road may be the cameras through which the tracking target will pass on the driving road. The embodiment of the application does not limit the number of the cameras, the distribution of the cameras on different driving roads and the like, and the cameras can be specifically set according to user requirements.
In order to select a camera with a higher probability of the tracking target from a plurality of cameras positioned on the traveling road as a camera through which the tracking target will pass on the traveling road, so as to improve the accuracy of predicting the camera through which the tracking target will pass on the traveling road, in another possible embodiment, the camera through which the tracking target will pass on the traveling road is predicted, and the camera includes:
determining the running speed of the tracking target; a camera to be photographed by a tracking target at a traveling speed with a current position as a starting point is predicted on a traveling road.

Step S104: and playing a monitoring picture of the camera, and identifying the tracking target by using the monitoring picture.
After the camera is determined, the monitoring picture shot by the camera is played on the display screen of the terminal equipment. If the number of the cameras is one, the tracking target can be identified by playing the monitoring picture of the camera and utilizing the monitoring picture of the camera; if the number of the cameras is multiple, the monitoring images of some or all of the cameras in the multiple cameras can be played, and when the tracking target is identified by using the monitoring images, the monitoring images shot by all the cameras can be identified, and the monitoring images shot by some high-performance cameras can also be identified, which is not limited by the embodiment of the present application.
When the tracking target is a target vehicle, in order to recognize the tracking target, vehicle information of the tracking target needs to be acquired, and acquiring the vehicle information of the tracking target may be implemented by inputting vehicle information of the tracking target by a user, for example, inputting a picture or a video of the tracking target, and then recognizing the vehicle information of the tracking target from a monitoring picture by using an image recognition technology, which is not limited in the embodiment of the present application. In addition, the information content of the tracking target vehicle is not limited in the embodiments of the present application, and may be, for example, the basic feature of the tracking target or the feature information of the driver driving the tracking target. In one possible embodiment, the vehicle information includes at least one of: license plate number, vehicle type, vehicle color, driving direction, driving speed and driver image.

When the suspected target identified by the camera meets the first set condition, the suspected target is determined to be the tracking target, so that the automatic determination of the tracking target is realized, and the tracking efficiency is improved; when the suspected target identified by the camera does not meet the first set condition, the artificially specified suspected target is determined to be the tracking target, so that the accuracy of the tracking target is improved.
Optionally, the first preset condition is that the similarity between the suspected target and the tracked target is greater than or equal to a first preset threshold. The size of the first preset threshold is not limited in the embodiment of the present application, for example, the first preset threshold is 90%.
In a possible implementation manner, if the identified suspected target does not satisfy the first setting condition, determining the tracking target according to a user instruction includes:
if the similarity between the suspected target and the tracking target is smaller than a first preset threshold and larger than or equal to a second preset threshold, recommending the suspected target to the user as the tracking target; if a tracking target changing instruction for changing the tracking target is not received within a first preset time period, determining the suspected target as the tracking target; and if the tracking target changing instruction is received within the first preset time period, determining that the target changed by the user is the tracking target.
In the embodiment of the application, when the similarity between the suspected target and the tracking target is smaller than a first preset threshold and larger than or equal to a second preset threshold, the suspected target is recommended to a user as the tracking target, and the user is waited to determine whether to use the suspected target as the tracking target by setting the preset time, so that the problem that the tracking target is not the suspected target or the suspected target is not the tracking target is effectively solved, the tracking target is confirmed through manual control of the user when the suspected target is not the tracking target, the accuracy of the tracking target is favorably improved, and the user experience can be enhanced.
And if the similarity between the suspected target and the tracking target is smaller than a second preset threshold, receiving a tracking target confirmation instruction of the user, and determining the tracking target instruction to be used for determining the tracking target. In the embodiment of the application, when the tracking target cannot be confirmed, the tracking target is determined by receiving the instruction of the user, so that the accuracy of tracking target identification can be improved, and the user experience can be enhanced.
Optionally, identifying the tracking target may further determine a suspected target with the largest similarity to the tracking target as the tracking target, which is not limited in this embodiment of the application.

if the current position of the tracking target is not changed within the second preset time, stopping tracking the tracking target; or receiving a target tracking stopping instruction of the user to stop tracking the tracking target.
If the current position of the tracked target does not change within the second preset time, it indicates that the tracked target stops for the second preset time, in this case, the tracked target does not need to be tracked any more, and the tracked target can be stopped. Alternatively, the terminal device may receive a user instruction to stop tracking the target. For example, the target tracking stopping instruction of the user may be received by setting a button or a virtual key, which is not limited in the embodiment of the present application.
