Abstract
A method for detecting body information on passengers of a vehicle based on humans' status recognition is provided. The method includes steps of: a passenger body information-detecting device, (a) inputting an interior image of the vehicle into a face recognition network, to detect faces of the passengers and output passenger feature information, and inputting the interior image into a body recognition network, to detect bodies and output body-part length information; and (b) retrieving specific height mapping information by referring to a height mapping table of ratios of segment body portions of human groups to heights per the human groups, acquiring a specific height of the specific passenger, retrieving specific weight mapping information from a weight mapping table of correlations between the heights and weights per the human groups, and acquiring a weight of the specific passenger by referring to the specific height.
