S2, capturing the positions of pedestrians in the scenic spots in the real world, and projecting the positions as statistical points into a three-dimensional model according to three-dimensional coordinates.
It can be understood that the position for capturing the pedestrian is the signal sent by the mobile terminal carried on the pedestrian, the mobile terminal can be realized by downloading the appointed APP by using the mobile phone in the hand of the pedestrian, and the mobile terminal can be used as an electronic card needing to be retracted such as a ticket and the like to be issued to the pedestrian when the pedestrian enters the scenic spot.
Specifically, the position of capturing the pedestrian is captured through a signal receiving and transmitting platform arranged at a marked sightseeing spot and a rest spot, the position coordinates of the signal receiving and transmitting platform are set, and when the distance between the pedestrian and the signal receiving and transmitting platform is smaller than a specified distance, the pedestrian is judged to be positioned in the corresponding sightseeing spot or rest spot. The rest point can be a rest pavilion, a tea garden or a restaurant and other places capable of sitting for rest.
It can be understood that the signal transceiver station will locate the position of the pedestrian in real time, and take the signal transceiver station closest to the pedestrian as a candidate, and when the distance between the pedestrian and the signal transceiver station is smaller than the specified distance, the pedestrian is considered to have entered the corresponding scenic spot or rest point. In this embodiment, the specified distance is selected to be 100 meters.
In addition, when the distance between the pedestrian and the signal receiving and transmitting platform is smaller than the specified distance, timing is conducted on the pedestrian until the distance between the pedestrian and the signal receiving and transmitting platform is larger than the specified distance, and the duration time is recorded.
In this embodiment, the mobile terminal may generate signals with different characteristics so that the signal transceiver station can identify whether the signal transceiver station is the same person, the duration of the timing station corresponds to the same pedestrian and the same scenic spot, and when the pedestrian moves to other scenic spots, another timing station is started for the pedestrian, and the signal transceiver station cannot be overlapped on the previous duration.
And S3, calculating the number of statistical points in an area with any appointed size in one day in the three-dimensional model, and judging the area as a recommended point when the number of the statistical points is larger than a threshold value.

when the accumulated time is greater than the specified time, the value of the number of statistical points is increased by 1.
In this embodiment, the cumulative time takes 30 minutes.
It should be noted that the number of statistical points is the accumulated time calculated for the same sight point for different pedestrians, 1 is increased for the number of statistical points when one pedestrian is greater than the specified time, 2 is increased for the number of statistical points when two pedestrians satisfy the above condition, and so on.
In addition, the liveness of the corresponding scenic spot or rest point is calculated according to the following formula:
liveness = number of statistics points x cumulative time
