A method for detecting passenger statuses by analyzing a 2D interior image of a vehicle is provided. The method includes steps of: a passenger status-detecting device (a) inputting the 2D interior image taken with a fisheye lens into a pose estimation network to acquire pose points corresponding to passengers; and (b) (i) calculating location information on the pose points relative to a preset reference point by referring to a predetermined pixel-angle table, if a grid board has been placed in the vehicle, the pixel-angle table has been created such that vertical angles and horizontal angles, formed by a first line and second lines, correspond to pixels of grid corners, in which the first line connects a camera and a top center of the grid board and the second lines connects the corners and the camera and (ii) detecting the passenger statuses by referring to the location information.
