The invention discloses a vehicle-mounted positioning and speed measuring device for an urban rail train. The vehicle-mounted positioning and speed measuring device is specifically characterized in that an outer shell is fixed on a mounting bracket at the bottom of the train through outer edge bolt hole mounting bolts at the top of the device; an upper spring, an upper double-flange structure, a camera fixing mechanism, a lower double-flange structure and a lower spring are sequentially mounted in the outer shell from top to bottom to form a single-degree-of-freedom vibration reduction system; an industrial camera is installed on the camera fixing mechanism, and the control/drive integrated board is fixed in the upper double-flange structure. A light inlet of the industrial camera is provided with an LED light source and transparent dustproof tempered glass, and a rubber water-stop belt is arranged between the dustproof tempered glass and the outer shell; the top of the outer shell is provided with a waterproof aviation plug used for equipment wiring. Visual velocity measurement based on real-time image processing has the advantages of being low in cost, resistant to vibration, dustproof, waterproof and high in integration degree on the premise that velocity measurement precision is achieved.
