A passive human detection method and apparatus, a device, and a medium are provided. The passive human detection method includes: acquiring an infrared radiation signal in an environment, and acquiring a temperature of a target object; emitting an electromagnetic wave into the environment, and acquiring a reflected echo signal; determining a position of the target object in the environment based on the echo signal; matching a threshold range based on the position of the target object; and comparing the temperature of the target object with the threshold range to determine detection information of a human in the environment. The passive human detection method combines electromagnetic wave detection and thermal imaging to detect whether there is a human in the current environment. The passive human detection method can effectively filter out interference signals, greatly improving the accuracy and sensitivity of human detection.
