In addition, the safety accident is avoided by adjusting the opening time of the gate.
The following specifically explains how to determine the moving speed of the target user based on the target video:
optionally, the determining the moving speed of the target user based on the target video comprises:
determining, based on the target video, a first duration for the target user to move from the first location to the second location;
and determining the moving speed of the target user according to the first time length and the distance from the first position to the second position.
As described above, the video content of the target video includes a scene in which the target user moves from the first position to the second position according to the preset direction, and then, a duration corresponding to the video scene in which the target user moves from the first position to the second position in the target video is obtained, and the duration is referred to as a first duration.
It should be understood that the first position and the second position are preset, and as described above, the position where the first reference object preset in the shooting scene is located may be referred to as the first position, and the position where the second reference object preset in the shooting scene is located may be referred to as the second position, and then, the distance between the first position and the second position is also preset.
In this embodiment, the moving speed of the target user is determined according to a first duration of the target user moving from the first location to the second location and a distance between the first location and the second location.
For example, if the distance from the first location to the second location is 5 meters and the first time period for the target user to move from the first location to the second location is 5 seconds, the moving speed of the target user may be determined to be 1 meter/second.
Optionally, the determining the moving speed of the target user based on the target video comprises:
for any adjacent position of the first position, the second position and the at least one third position, acquiring a target distance and a target duration between the adjacent positions;
determining a target speed corresponding to the adjacent position based on the target distance and the target duration;
and determining the moving speed based on the target speed, wherein the moving speed is the average value of the target speeds corresponding to the adjacent positions.
In this embodiment, at least one third position is included between the first position and the second position, and the third position may be understood as a position where a third reference object preset in the shooting scene is located.
For ease of understanding, referring to fig. 3, in the scenario shown in fig. 3, a third reference object is included between the first reference object and the second reference object, and the third reference object is located at a third position, so that the first position and the third position can be determined as adjacent positions, and the second position and the third position can be determined as adjacent positions. It will be appreciated that in other scenarios, a plurality of third references may be included between the first reference and the second reference, i.e. a plurality of third locations may be included between the first location and the second location.
And for any adjacent position, acquiring a target distance and a target time length between the adjacent positions, wherein the target time length is a time length corresponding to the target user moving from a former position of the adjacent positions to a latter position of the adjacent positions according to a preset direction. Further, a target speed corresponding to the adjacent position is determined based on the target distance and the target duration, and optionally, a division result between the target distance and the target duration is determined as the target speed corresponding to the adjacent position.
In this embodiment, after the target speeds corresponding to the adjacent positions are obtained, an average value of the target speeds corresponding to the adjacent positions may be determined as the moving speed of the target user.
For ease of understanding, referring to fig. 3, in the scenario shown in fig. 3, the first position and the third position are referred to as a first adjacent position, the target distance between the first position and the third position is 5 meters, and the target time duration is 5 seconds, then the target speed corresponding to the first adjacent position may be determined to be 1 meter/second. And the third position and the second position are called as second adjacent positions, the target distance between the third position and the second position is 3 meters, and the target duration is 1.5 seconds, so that the target speed corresponding to the second adjacent positions can be determined to be 2 meters/second. In this way, the average value of the target speed corresponding to the first adjacent position and the target speed corresponding to the second adjacent position is 1.5 m/s, and is determined as the moving speed of the target user.
In this embodiment, the average value of the target speeds corresponding to each adjacent position of the target user is determined as the moving speed of the target user, so as to obtain a more accurate moving speed, and further, in the setting process of the subsequent gate opening time period, the gate opening duration is more accurately adjusted.
Optionally, the target video, determining the moving speed of the target user includes:
determining, based on the target video, a first length of time that the target user moved from the first location to the fourth location;
obtaining a first distance between the first position and the fourth position;
and determining the moving speed of the target user according to the first time length and the first distance.
In this embodiment, at least one fourth position is included between the first position and the second position, and the fourth position may be understood as a position where a preset reference object is located in the shooting scene.
For example, in the scenario shown in fig. 3, a third reference object is included between the first reference object and the second reference object, and the position of the third reference object may be determined as the fourth position.
In this embodiment, the fourth position is located between the first position and the second position, and the target user must pass through the fourth position in the process that the target user moves from the first position to the second position. In this way, the duration and distance that the target user moves from the first location to the fourth location, also referred to as the second duration, and the distance, also referred to as the first distance, may be obtained. Further, the moving speed of the target user is determined based on the division result between the first distance and the second time length.
For example, if the distance between the first location and the fourth location is 6 meters and the length of time for the target user to move from the first location to the fourth location is 3 seconds, the moving speed of the target user may be determined to be 2 meters/second.
In this embodiment, in the case that the fourth location is included between the first location and the second location, the moving speed of the target user may be determined only according to the duration and the distance between the first location and the fourth location, so that the calculation steps in the process of determining the moving speed of the target user are reduced, and thus the moving speed of the target user may be determined quickly based on the target video.
Further, in the case where a fourth position is included between the first position and the second position, when the moving speed of the target user is determined based on the target video, a length of time for which the target user moves from the fourth position to the second position may also be determined based on the target video; acquiring the distance between the fourth position and the second position; and determining the moving speed of the target user according to the duration and the distance.
For example, if the distance between the fourth location and the second location is 4 meters and the time period for the target user to move from the fourth location to the second location is 2 seconds, the moving speed of the target user may be determined to be 2 meters/second.
In this embodiment, in the case that the fourth location is included between the first location and the second location, the moving speed of the target user may be determined only according to the duration and the distance between the fourth location and the second location, so that the calculation steps in the process of determining the moving speed of the target user are reduced, and thus the moving speed of the target user may be determined quickly based on the target video.
In this embodiment, the fourth position is located between the first position and the second position, and the target user must pass through the fourth position in the process that the target user moves from the first position to the second position. In this way, the length of time and the distance that the target user moves from the fourth location to the second location can be obtained. Further, the moving speed of the target user is determined based on a division result between a distance between the fourth position and the second position and a time period for the target user to move from the fourth position to the second position.
Optionally, the determining, according to the moving speed, the first preset distance, and the second preset distance, an opening time period of the gate includes:
determining a third time length and a fourth time length according to the moving speed, the first preset distance and the second preset distance;
determining the sum of the target time and the third duration as the starting time;
and determining the sum of the opening time and the fourth duration as the closing time.
In this embodiment, a third time length and a fourth time length may be determined according to the moving speed, the first preset distance and the second preset distance, where the third time length is used to represent a time length that the target user moves from the gate passageway entrance to the gate door, and the fourth time length is used to represent a time length that the target user passes through the gate passageway. Please refer to the following embodiments specifically for how to determine the third duration and the fourth duration.

For example, if the target time is 18:00:00 and the third time period is 30 seconds, the opening time of the gate is 18:00: 30. In the case of a fourth time period of 5 seconds, the closing time of the gate is 18:00: 35.
