[0018] like Figure 1 As shown, the present application provides a trajectory determination method, which includes the following steps: Step S110, obtaining first trajectory information of the target object at a previous time point, wherein the first trajectory information includes corresponding first coordinate information.
[0019] In this embodiment, the target object includes a target device or a target person, and the first trajectory information includes position information corresponding to the target device or the target person at a previous time point. The position information is usually expressed in coordinates, that is, first coordinate information.
[0020] The previous time point should be understood as the time point corresponding to the last trajectory information of the target object relative to the current time point, and the first trajectory information should be understood as the trajectory information corresponding to the last time point of the target object.
[0021] Step S120, obtaining second trajectory information of the target object at the current time point, wherein the trajectory information includes corresponding second coordinate information.
[0022] The second trajectory information includes the position information corresponding to the target device or the target person at the current time point. The position information is usually expressed in coordinates, that is, second coordinate information.
[0023] Step S130, calculating the speed of the target object according to the previous time point and the corresponding first coordinate information, and the current time point and the corresponding second coordinate information.
[0024] Step S140: comparing the speed of the target object with a preset speed threshold.
[0025] Step S150: When the speed of the target object is less than the preset speed threshold, it is determined that the trajectory information is normal, and the second coordinate information and the corresponding timestamp are written into the trajectory database corresponding to the target object.
[0026] In this embodiment, when the speed of the target object is greater than or equal to the preset speed threshold, the trajectory information is judged to be abnormal and an alarm is issued.
[0027] In this embodiment, by analyzing the first trajectory information corresponding to the target object at the previous time point and the second trajectory information corresponding to the current time point, the speed of the target object is calculated, and the speed of the target object is compared with a preset speed threshold to determine whether the trajectory information of the target object is normal. When the trajectory information of the target object is normal, the second coordinate information and the corresponding timestamp are written into the trajectory database corresponding to the target object, so that the trajectory information of the target object can be accurately identified.
[0028] In one embodiment, step S110 includes: A preset trajectory database is queried to obtain first trajectory information of the target object at a previous time point.
[0029] In this embodiment, when establishing a preset trajectory database, it is necessary to filter the abnormal coordinate information in the trajectory information to remove zero values and integer values.
[0030] like Figure 2 As shown, in one embodiment, the second trajectory information also includes the IP address information of the target object, and the trajectory determination method further includes: S160: When the preset trajectory database is queried and no first trajectory information of the target object at a previous time point is obtained, the location corresponding to the IP address information of the target object is obtained.
[0031] S170, determining whether the address corresponding to the second coordinate information is located within the belonging place, and if so, determining that the trajectory information is normal, and writing the second trajectory information and the corresponding timestamp into the preset trajectory database.
[0032] In this embodiment, when the preset trajectory database is queried and the first trajectory information of the target object at the previous time point is not obtained, the place of origin corresponding to the IP address information of the target object is further obtained to determine whether the address corresponding to the second coordinate information is located within the place of origin, thereby determining that the trajectory information is normal, thereby further improving the availability and accuracy of the above-mentioned trajectory judgment method.
[0033] In one embodiment, when the address corresponding to the second coordinate information is not located at the belonging place, the trajectory information is determined to be abnormal.
[0034] In one embodiment, the step of writing the second trajectory information and the corresponding timestamp into the preset trajectory database in step S170 includes: The second trajectory information and the corresponding timestamp are used as the latest trajectory information of the target object to be written into the preset trajectory database.
[0035] In one embodiment, the step of writing the second trajectory information and the corresponding timestamp as the latest trajectory information of the target object into the preset trajectory database includes: The current time point is written to cover the first time point, and the second track information is written to cover the first track information.
[0036] In this embodiment, in order to improve the screening efficiency, the current time point may be written into the preset trajectory database to cover the first time point, and the second trajectory information may be written to cover the first trajectory information.
[0037] In one embodiment, after the step of writing the current time point to cover the first time point and writing the second track information to cover the first track information, the step further includes: It is determined whether the retention time after writing of the second track information is greater than a preset time threshold, and if so, the second track information and the corresponding timestamp are deleted.
[0038] In this embodiment, the retention time of the last occurrence of the target object's trajectory information can be set. For example, when the retention time after the second trajectory information is written is greater than a preset time threshold, the second trajectory information and the corresponding timestamp are deleted.
