A portrait recognition and accurate temperature measurement method based on an infrared thermal imaging camera comprises the steps that S1, the infrared thermal imaging camera is turned on to collect an image, pseudo-color processing is carried out on the whole frame of image, and a YOLOv5 algorithm is called to carry out portrait and head shielding object recognition on the image; s2, if the image does not have the object to be detected, automatically detecting the next frame and continuously identifying; if the YOLOv5 detects a human image and a shielding object, carrying out the next step of image processing; s3, recording the coordinates of the regression frame of the detected image, then calculating the coordinates of the temperature measurement area according to the coordinates of the regression frame, and for the portrait with the shielding object, performing joint calibration in combination with the portrait non-shielding temperature measurement area and the corresponding shielding object recognition
