The invention discloses an intelligent parking guide system and method, and the system comprises a data collection module which is used for collecting license plate information, parking lot state information and user selection information, a database module which is used for storing data, a data processing module which is used for path planning, and a path indication module which is used for displaying a parking path. A user selects 'the easiest parking' or 'the shortest distance', and then the data collection information collects license plate information. The license plate information is stored by the database module, and is transmitted to the data processing module for path planning. The path information is displayed through an LED display screen. After a driver enters a parking place, an infrared sensor enables the occupying information of the parking place to be transmitted to the data processing module through the wireless transmission module, and a parking place level calculation module recalculates the parking place level and refreshes the original data, and simultaneously sends an instruction to the path indication module to delete the indication information of the vehicle on the LED display screen. The system can guide a vehicle according to the user selection through combining with the real-time parking information of the parking lot, is simple and convenient and is high in practicality.
