The invention relates to the field of rail transit, in particular to a high-low speed train passing accurate triggering device and an imaging triggering method thereof, and the device comprises a sensor unit and an imaging unit group which are arranged along a steel rail; the sensor unit is used for outputting real-time signals generated by a train wheel triggering sensor, and the imaging unit group is used for receiving the real-time signals, dynamically adjusting the imaging triggering time and collecting images. According to the invention, when a train passes through an image acquisition equipment area at different train passing speeds, the image of a specific part is accurately acquired, the image position deviation is effectively controlled, the speed measurement is accurate, and the required image is accurately acquired by utilizing speed measurement prediction triggering. Effective coverage in a full-speed range can be realized, and high position consistency of the target component in the image can be guaranteed. In addition, by the adoption of the device structure, the sensor can be installed on the inner side of the steel rail or the outer side of the steel rail, and the space utilization rate of the device is extremely high.
