The utility model relates to the technical field of night vision devices, in particular to an ultrasonic low-light level night vision device with a human body induction function, which comprises a power supply control module, a microprocessor, an active ultrasonic ranging module, a first imaging system and a second imaging system. The first imaging system and the second imaging system are the same in structure and are symmetrically arranged on the two sides of the microprocessor, the active ultrasonic ranging module is used for detecting the use state of the low-light-level night vision device, detecting the distance of the head position and judging whether the low-light-level night vision device is correctly worn or not, and therefore the low-light-level night vision device can be turned on or turned off in time. The image intensifier of the low-light-level night-vision device is protected, stable and abnormal imaging of the low-light-level night-vision device is guaranteed, the service life of the low-light
