Disclosed are a method for counting regional population, a computer device and a computer readable storage medium. The method for counting regional population includes: acquiring an image to be analyzed in a target region; detecting a position of each first human body part in the image to be analyzed; determining, according to the position of each first human body part in the image to be analyzed and a first transformation relation, a physical position of each first human body part in the target region; and determining the population in each sub-region according to a relative positional relation between the position of the first human body part in the image to be analyzed and the sub-image, as well as a relative positional relation between the physical position of the first human body part and the sub-region.
