Published: with international search report (Art. 21(3)) (54) Title: METHOD OF HUMAN BODY RECOGNITION AND HUMAN BODY RECOGNITION SENSOR (57) : The invention relates to a method of human body recog- 16 nition by analysing a detected object (P) in a monitored area and decid- ing whether or not the detected object is a human being with a laser scanner (12) comprising: the laser scanner (12) generates at least one laser curtain ( 22, 32, 34), where each laser curtain (22, 32, 34) is gen- erated by multiple pulses evaluated by time of flight (TOF) measure- ment of single pulses to generate the distance of the points of reflection with respect to the laser scanner position; combination of distances of the points of reflection with the direction of the pulse to retrieve a posi- tion in a predefined detection zone within a monitored area; projecting the points of reflection belonging to a detected object into an evaluation plane (EP) as evaluation objects (01, 02), where the evaluation plane (EP) has a Z-axis that is related to the height and a perpendicular one to the Z-axis that is related to the width in the direction of the lateral extension of the laser curtain (22, 32, 34). The invention is characterized in that the evaluation plane (EP) is evaluated based on the density dis- 14 tribution of the points of reflection along the Z-axis and the evaluation result is compared to anthropometric parameters.
