The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A movement trace display method and apparatus according to an embodiment of the present invention will be described below with reference to the drawings.
Fig. 1 is a schematic flow chart of a motion trajectory display method according to an embodiment of the present invention.
As shown in fig. 1, the method includes:
in step S101, a first position of a first object at each time is acquired.
In this embodiment, two objects are taken as an example to describe the motion track display method.
Specifically, for the objects that need to be subjected to trajectory analysis, for the sake of convenience of distinction, one of the objects is referred to as a first object, and the position of the first object at each time is acquired and referred to as a first position.
Step S102, a second position of the second object at each moment is obtained.
Specifically, another object is referred to as a second object, the first object and the second object are relative concepts, and the position of the second object at each time is acquired and referred to as a second position.
Step S103, counting the distance between the first position of the first object and the second position of the second object at each moment in a preset time period.
Specifically, for a preset time period, the time period includes a plurality of moments, each moment corresponds to a first position where the first object is located and a second position where the second object is located, and the distance between each moment in the preset time period and the first position where the first object is located and the second position where the second object is located is counted.
For example, the preset time period is one day, and table 1 counts the distance between the first object and the second object during a preset time period, i.e. different times of the day, as shown in table 1,
| time of day | Distance of first object and second object |
| Time 1 | 1 m |
| Time 2 | 2 m |
| Time 3 | 3 m |
| Time 4 | 5 m |
| Time 5 | 10 m |
| Time 6 | 300 m |
| Time 7 | 2 kilometers |
| Time 8 | 5 kilometers |
| Time 9 | 8 kilometer |
| Time 10 | 10 kilometers |
| Time 11 | 15 kilometers |
TABLE 1
And step S104, generating a K line graph corresponding to the preset time interval according to the distance of each moment in the preset time interval.
The K line drawing comprises an entity part, and an upper shadow line and a lower shadow line which are connected with the upper edge and the lower edge of the entity part and extend outwards, specifically, firstly, the maximum value and the minimum value of each distance in a preset time period are counted, and in the distance of each moment, the distance of the front X% and the distance of the rear Y% are sequenced, the upper endpoint of the upper shadow line is determined according to the maximum value, the lower endpoint of the lower shadow line is determined according to the minimum value, the upper edge position of the entity part is determined according to the distance of the front X% and the lower edge position of the entity part is determined according to the distance of the rear Y%. Then, judging whether a distance smaller than a threshold exists in a preset time period, if so, determining that the first object and the second object meet at a moment corresponding to the distance smaller than the threshold, and generating an entity part in a filling state; if not, determining that the first object and the second object do not meet at the moment corresponding to the distance smaller than the threshold distance, and generating a solid part in an unfilled state.

The entity portion is used to indicate an encounter condition of the first object and the second object within a preset time period, and if the first object and the second object encounter within the preset time period, the entity portion is in a filled state, such as the left entity in fig. 2, and if the first object and the second object do not encounter within the preset time period, the entity portion is in an unfilled state, such as the right entity in fig. 2. The upper edge position of the entity part represents the distance of X% in the distance of each moment in a preset time period; the lower edge position of the solid part represents the distance of Y% after sorting in the distances of each moment in the preset time period.
For example, with X% ═ 20% and Y% ═ 20%, according to table 1, the parameters of the K line plot can be determined as: the upper end point of the upper hatching is 15 kilometers, the upper edge position of the solid part is 8 kilometers, the lower edge position of the solid part is 3 meters, and the lower end point of the lower hatching is 1 meter.

In the movement track display method of this embodiment, a first position of a first object at each time is obtained, a second position of a second object at each time is obtained, for each time within a preset time period, a distance between the first position where the first object is located and the second position where the second object is located is counted, a K-line graphic representation corresponding to the preset time period is generated according to the distance at each time within the preset time period, and the K-line graphic representation corresponding to the preset time period is displayed when the movement track of the first object is displayed according to the first position and the movement track of the second object is displayed according to the second position. The movement tracks of different objects in time and space are represented by the K-line graph, so that the problems that in the prior art, when the movement tracks of different objects are displayed by adopting a two-dimensional plane of a map, information in time and space cannot be simultaneously expressed, whether different objects are intersected in time and space cannot be clearly displayed, the visualization is not realized, and the efficiency is low are solved.
