Method for automatically judging whether tourists fall behind

Abstract

The invention discloses a method for automatically judging whether tourists fall behind, which adopts the technical scheme for effectively monitoring the fallen behind tourists in group tour: calculating the Euclidean distance between each tourist and other n-1 tourists to obtain a distance sum; analyzing the distance sum, screening out special tourists, calculating average value of the distance sum of the rest of the tourists, and calculating the relative continuous distance between two tourists according to the average value so as to generate a relative continuous area; acquiring intersection of all relative continuous areas and performing calculation to obtain a main branch group and an auxiliary branch group; and judging the containing relation of the special tourists and the branch groups the special tourists belong to, and finally determining the fallen behind tourists according to fallen behind tourist judging conditions. The method can judge the fallen behind tourists timely, accurately and automatically, and can estimate the current dispersion degree of the group according to the relative continuous distance between two tourists so as to avoid and reduce phenomena of tourists falling behind.

Description

technical field [0001] The invention relates to a method that is applied to the fields of intelligent scenic spot tour guides, safety monitoring, etc., and can automatically judge that tourists are left behind. Background technique [0002] In recent years, the construction of smart scenic spots has been gradually carried out. Many scenic spots have provided portable smart terminal services. While providing tourists with scenic spot explanations, they can also obtain tourist terminal location information to realize dynamic monitoring of tourists. Due to tourists' lack of understanding of the geographical distribution of scenic spots and their great curiosity, coupled with factors such as different ages, different cultural backgrounds, different interests, and different physical conditions, each tourist has different concerns about different scenic spots in the same scenic spot. , The travel speed is also different, resulting in a small number of tourists easy to get separate...
