Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another embodiment of a target tracking method according to the present application, the method including:
step S201: the first instruction sent by the second camera is obtained in response to the first camera, and the second instruction is being executed by the first camera.
Specifically, when the first camera obtains the first instruction sent by the second camera, the data of the second instruction being executed is extracted from the first camera, if the first camera does not have the second instruction being executed, the data is empty, and if the first camera includes the second instruction being executed, the priority information, the shortest execution cycle, and the first timestamp for starting execution of the second instruction are obtained.
Step S202: and judging whether the time for the first camera to execute the second instruction exceeds the shortest execution period corresponding to the second instruction.
Specifically, it is determined whether the difference between the current timestamp and the first timestamp is greater than the shortest execution period, if so, the process proceeds to step S205, and if not, the process proceeds to step S203.
Step S203: a first target included in the first instruction and a second target included in the second instruction are obtained.
Specifically, different types of targets correspond to different priority information, when the first camera detects a target, a request instruction is generated and a type corresponding to the target is added, and after the first camera acquires the first instruction or the second instruction, the priority information corresponding to the type of the first target included in the first instruction and the priority information corresponding to the type of the second target included in the second instruction are extracted.
In one application mode, the types of the targets shot by the second camera and the third camera are the same or different, and different types of the targets have different priority information. The step of obtaining a first target included in the first instruction and a second target included in the second instruction includes: the type of the first target and the corresponding priority information contained in the first instruction are obtained, and the type of the second target and the corresponding priority information contained in the second instruction are obtained.
Specifically, different types of targets are provided with different priority information, wherein the hierarchy of the priority information is associated with the moving speed or the degree of importance of the target.
In an application scene, pedestrians, non-motor vehicles and motor vehicles are respectively provided with priority information with the levels from low to high, the moving speed of the pedestrians is slow, the moving time in the whole monitoring range is long, so that the level of the priority information is the lowest when the pedestrians are targeted, and when the motor vehicles are targeted, the moving time of the motor vehicles in the whole monitoring range is short, so that the level of the priority information is the highest when the motor vehicles are targeted, and important information such as license plates of the motor vehicles and the like can be captured as soon as possible.
In another application scenario, the pedestrians in the preset uniform and the pedestrians in the non-preset uniform are provided with priority information from low to high in level, and the pedestrians in the preset uniform can acquire face or body feature information as workers in advance, so that the level of the priority information is the lowest, and the pedestrians in the non-preset uniform do not acquire the face or body feature information at a higher probability, so that the pedestrians in the non-preset uniform need to be tracked as soon as possible and the level of the priority information is the highest.
Further, in response to the first camera starting to execute the second instruction, the priority information corresponding to the type of the second target in the second instruction is stored, in response to the first camera acquiring the first instruction sent by the second camera, the first camera stores the priority information corresponding to the type of the first target in the first instruction, and the first camera side performs a unified decision on the instruction execution sequence through the priority information, so that a decision layer is prevented from being arranged on the second camera or the third camera side, the first camera makes a decision uniformly, and the order of instruction execution is improved.
Step S204: it is determined whether the priority information of the first object is higher than the priority information of the second object.
Specifically, in response to the priority information of the first target being higher than the priority information of the second target, the first camera executes the first instruction to track the corresponding target, proceeding to step S205. In response to the priority information of the first target not being higher than the priority information of the second target, the first camera continues to execute the second instruction, and proceeds to step S206.
Step S205: the first camera executes the first instructions to track the corresponding target.
Specifically, the first camera executes the first instruction to track a target included in the first instruction, saves priority information and a shortest execution cycle corresponding to the first instruction, acquires a first timestamp when the first instruction starts to be executed, and marks the first instruction as a second instruction being executed.
Step S206: the first camera continues to execute the second instruction.
Specifically, the first camera continues to execute the second instruction to continue tracking the target included in the second instruction, and continues to wait whether other first instructions are sent to the first camera.
In an application mode, judging whether other instructions are received before the second instruction reaches the shortest execution cycle; if so, discarding the first instruction and taking other instructions as new first instructions, and then returning to the step that the first camera executes the instruction related to the highest priority information based on the priority information related to the first instruction and the second instruction; otherwise, the first camera executes the first instruction to track the corresponding target.
Specifically, when the difference between the current timestamp for executing the second instruction and the first timestamp exceeds the shortest execution period and no instruction is received, the first camera executes the first instruction to track the corresponding target, so that the integrity of instruction execution is improved, and the first instruction sent by the second camera can be executed by the first camera as far as possible. And when the difference value between the current timestamp for executing the second instruction and the first timestamp does not reach the shortest execution period, receiving other instructions, discarding the first instruction with the previous time sequence, taking the other instructions as the first instruction, judging the size relationship of the priority information of the new first instruction and the second instruction, and determining to continue executing the second instruction or execute the first instruction based on the size relationship.
According to the scheme, the first instruction and the second instruction comprise the type of the target, the type of the target corresponds to the priority information, and further how to execute the first instruction or the second instruction is decided by the first camera on the basis of the hierarchy of the priority information and the shortest execution cycle of the second instruction, so that the complexity of the system is reduced, and the decision efficiency is improved.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating a target tracking method according to another embodiment of the present application, the method including:
step S301: the first instruction sent by the second camera is obtained in response to the first camera, and the second instruction is being executed by the first camera.
Step S302: and judging whether the time for the first camera to execute the second instruction exceeds the shortest execution period corresponding to the second instruction.
Specifically, the steps S301 to S302 are similar to those described above, and the description of the related contents refers to the detailed description of the above embodiments, which is not repeated herein.
Step S303: the first camera executes the first instructions to track the corresponding target.
Specifically, the first camera executes the first instruction to track a target included in the first instruction, saves priority information and a shortest execution cycle corresponding to the first instruction, acquires a first timestamp when the first instruction starts to be executed, and marks the first instruction as a second instruction being executed.
Step S304: priority information of a second camera that transmits the first instruction and priority information of a third camera that transmits the second instruction are obtained.
Specifically, the cameras except the first camera are divided into a plurality of camera groups, each camera group is allocated with corresponding priority information, and when the second camera or the third camera generates a request instruction, the corresponding priority information is added to the request instruction based on the camera group where the second camera or the third camera is located. After the first camera acquires the first instruction or the second instruction, the priority information of the second camera contained in the first instruction and the priority information of the third camera contained in the second instruction are extracted.
In one application, the second camera and the third camera belong to the same or different camera groups, and the different camera groups have different priority information. The step of obtaining priority information of a second camera sending the first instruction and priority information of a third camera sending the second instruction includes: and acquiring priority information of a camera group where a second camera sending the first instruction is located and priority information of a camera group where a third camera sending the second instruction is located.
Specifically, cameras other than the first camera are divided into a plurality of camera groups, wherein each camera group corresponds to priority information, the hierarchy of which is associated with the position of the camera in the monitored site.
In an application scene, cameras except the first camera are provided with corresponding scores based on the importance degree of the position in the monitoring place, a plurality of score sections are selected based on the corresponding scores, the cameras belonging to the same score section are classified into the same camera group, and the higher the score, the higher the level of the priority information corresponding to the camera group is.
Further, in response to the first camera starting to execute the second instruction, the priority information of the camera group where the third camera sending the second instruction is located is stored, in response to the first camera obtaining the first instruction sent by the second camera, the first camera stores the priority information of the camera group where the second camera sending the first instruction is located, the first camera side performs a unified decision on the order of instruction execution through the priority information, a decision layer is prevented from being arranged on the second camera or the third camera side, the decision is made by the first camera in a unified manner, and the order of instruction execution is improved.
Step S305: the first camera executes an instruction related to the highest priority information based on a magnitude relationship of the priority information of the second camera and the priority information of the third camera.
Specifically, the magnitude relation between the priority information of the second camera and the priority information of the third camera is judged, and the first camera preferentially executes the instruction with the highest level of the priority information.
In an application mode, in response to the priority information of the second camera being higher than the priority information of the third camera, the first camera executes a first instruction to track the corresponding target; in response to the priority information of the second camera not being higher than the priority information of the third camera, the first camera continues to execute the second instruction.
Specifically, the second camera sending the first instruction corresponds to priority information, the third camera sending the second instruction corresponds to priority information, and then how to execute the first instruction or the second instruction is determined by the first camera based on the hierarchy of the priority information, so that the complexity of the system is reduced, and the decision efficiency is improved.
In another application, in response to the priority information of the second camera being higher than the priority information of the third camera, the first camera executes the first instruction to track the corresponding target; or, in response to the priority information of the second camera being lower than the priority information of the third camera, the first camera continues to execute the second instruction; or, in response to the priority information of the second camera being equal to the priority information of the third camera, acquiring a first target included in the first instruction and a second target included in the second instruction; in response to the priority information of the first target being higher than the priority information of the second target, the first camera executes a first instruction to track the corresponding target; in response to the priority information of the first target not being higher than the priority information of the second target, the first camera continues to execute the second instruction.
Specifically, when the priority information of the second camera is higher than the priority information of the third camera, the first camera executes the first instruction to track the corresponding target, and when the priority information of the second camera is lower than the priority information of the third camera, the first camera continues to execute the second instruction. When the priority information of the second camera is equal to the priority information of the third camera, a first target included in the first instruction and a second target included in the second instruction are obtained, and a size relationship between the priority information corresponding to the first target and the priority information corresponding to the second target is determined.
Further, a second camera sending the first instruction corresponds to priority information, a third camera sending the second instruction corresponds to priority information, the first camera makes a decision based on the priority information corresponding to the cameras in priority, if the priority information levels of the second camera and the third camera are the same, the first camera makes a decision based on the priority information corresponding to the type of the target, and then how to execute the instructions is decided by the first camera in a unified manner based on the priority information corresponding to the type of the target, and the judgment of the priority information of the first instruction and the priority information of the second instruction is divided into two levels so as to improve the reasonability of the first camera in executing the instructions.
