The invention provides a map-based parking lot vehicle positioning system and a map-based parking lot vehicle positioning method. The map-based parking lot vehicle positioning system comprises a communication device, an inertia navigation unit, a vehicle-mounted speedometer, a computing device and a displayer. The communication deice is used for acquiring parking information of a parking lot; the inertia navigation unit is used for acquiring heading angle changes and pitching angle changes of vehicles; the speedometer is used for acquiring travel distances of the vehicles; the computing device is used for matching sensor input with a parking lot map so as to acquire vehicle positions, and the method is based on double-matching of shapes and pitching angles; the displayer displays the parking lot map, parking space occupation information and the vehicle positions in real time. The parking lot map can be stored in the computing device offline and can be acquired online. The positioning system is scarcely influenced by environment, transformation of the parking lot is not needed, and drivers can find and drive to unoccupied parking spaces conveniently and quickly.
