The invention discloses an urban
public space vitality evaluation method based on multi-age group
behavior recognition, belongs to the field of space
vitality evaluation, and aims to solve the problem that an existing urban
public space vitality evaluation method lacks attention to
space use characteristics of different-age group groups. The method comprises the following steps: identifying behavior patterns of individuals in an urban
public space and labels of
age groups to which the individuals belong, synchronously extracting
space environment characteristics, forming a multi-
source data set, respectively counting key indexes such as activity frequency,

residence time of people of different
age groups in the space, and obtaining a comprehensive vitality
evaluation result of the people of the multiple
age groups. And training a regression or classification model by taking the multi-age group vitality
evaluation result as output data and taking the corresponding behavior pattern, the age tag and the
space environment feature as input data, and predicting the vitality
evaluation result of the crowd of each age group in the unevaluated space after the model is trained. The method is used for accurate evaluation and instructive optimization of spatial vitality of people of different age groups.
