and at least one projection device configured to project and display the range of the parking space to assist the parking of a vehicle in response to the division and dispatch of the parking space by the central control device. ## Claims ### Claim 1 A parking management system, including: a central control device configured to centrally manage the division and dispatch of a parking space; and at least one projection device configured to project and display the range of the parking space to assist the parking of a vehicle in response to the division and dispatch of the parking space by the central control device. ### Claim 2 (depends on 1) The parking management system as claimed in claim 1, further including: a first camera configured to obtain the size information of the vehicle; wherein the central control device divides and dispatches the parking space based on the size information of the vehicle. ### Claim 3 (depends on 1) The parking management system as claimed in claim 1, further including: a first camera configured to obtain the model information of the vehicle; and a database, having stored therein, a mapping table between model information and size information of vehicles; wherein the central control device obtains corresponding size information from the database based on the model information of the vehicle and divides and dispatches the parking space based on the size information of the vehicle. ### Claim 4 (depends on 1) The parking management system as claimed in claim 1, wherein the central control device is further configured to directly obtain from the vehicle its size information, or obtain from the vehicle its model information, and further obtain corresponding size information from a database based on the model information of the vehicle, wherein the database stores a mapping table between model information and size information of vehicles; and divide and dispatch the parking space based on the size information of the vehicle. ### Claim 5 (depends on 1) The parking management system as claimed in claim 1, further including: a second camera configured to obtain the actual parking position of the vehicle; wherein the central control device determines the charge for the vehicle based on the actual parking position of the vehicle and the division and dispatch of the parking space. ### Claim 6 (depends on 5) The parking management system as claimed in claim 5, wherein the central control device determines the remaining parking spaces based on the actual parking position of the vehicle in order to divide and dispatch other parking spaces. ### Claim 7 (depends on 5) The parking management system as claimed in claim 5, wherein when determining that the vehicle is not in the range of the parking space, the central control device causes the projection device to display an alert. ### Claim 8 (depends on 1) The parking management system as claimed in claim 1, wherein the dispatch instructs a user via sound or image. ### Claim 9 (depends on 1) The parking management system as claimed in claim 1, wherein the projection device is arranged to be movable on a track to project and display different parking spaces. ### Claim 10 (depends on 2, 3) The parking management system as claimed in claim 2 or 3, further including: a pressure sensor configured to detect whether there is a vehicle entering; wherein in response to the detection that there is a vehicle entering, the first camera is activated to obtain the information of the vehicle. ### Claim 11 (depends on 1) The parking management system as claimed in claim 1, wherein the central control device performs pre-allocation of parking spaces for the remaining parking spaces based on multiple factors, wherein priority weights with different orders of magnitude are set for different factors to determine the allocation order of the remaining parking spaces. ### Claim 12 A parking management method, including: dividing and dispatching a parking space by a central control device; and projecting and displaying the range of the parking space by a projection device to assist the parking of a vehicle in response to the division and dispatch of the parking space. ### Claim 13 (depends on 12) The parking management method as claimed in claim 12, further including: a first camera obtaining the size information of the vehicle; and the central control device dividing and dispatching the parking space based on the size information of the vehicle. ### Claim 14 (depends on 12) The parking management method as claimed in claim 12, further including: a first camera obtaining the model information of the vehicle; and the central control device obtaining corresponding size information from a database based on the model information of the vehicle and dividing and dispatching the parking space based on the size information of the vehicle, wherein the database stores a mapping table between model information and size information of vehicles. ### Claim 15 (depends on 12) The parking management method as claimed in claim 12, further including: the central control device obtaining from the vehicle its size information, or the central control device directly obtaining from the vehicle its model information, and further obtaining corresponding size information from a database based on the model information of the vehicle, wherein the database stores a mapping table between model information and size information of vehicles; and dividing and dispatching the parking space based on the size information of the vehicle. ### Claim 16 (depends on 12) The parking management method as claimed in claim 12, further including: a second camera obtaining the actual parking position of the vehicle; and the central control device determining the charge for the vehicle based on the actual parking position of the vehicle and the division and dispatch of the parking space. ### Claim 17 (depends on 12) The parking management method as claimed in claim 12, wherein the central control device determines the remaining parking spaces based on the actual parking position of the vehicle in order to divide and dispatch other parking spaces. ### Claim 18 (depends on 16) The parking management method as claimed in claim 16, wherein when determining that the vehicle is not in the range of the parking space, the central control device causes the projection device to display an alert. ### Claim 19 (depends on 12) The parking management method as claimed in claim 12, wherein the dispatch instructs a user via sound or image. ### Claim 20 (depends on 13) The parking management method as claimed in claim 13, further including: a pressure sensor detecting whether there is a vehicle entering; and in response to the detection that there is a vehicle entering, activating the first camera to obtain the information of the vehicle.
