The invention relates to the technical field of infrared temperature measurement, and discloses an infrared temperature measurement method and system with a face recognition function. The method comprises the following steps: tracking a motion track of a human body in a video sequence collected by a camera through a tracking algorithm; performing light source detection on the video sequence according to a preset interval time, and performing image enhancement processing if the scene is a night scene; performing visibility detection by using a pre-trained visibility detection model, recording a visibility value, and performing restoration processing on an image of which the visibility value is lower than a threshold value; identifying character identity information tracked by the tracking algorithm in the image and positioning a forehead position of a human body; performing infrared temperature measurement on the forehead position; and carrying out environment and distance temperature compensation on the infra
