For better understanding of the present invention, referring to fig. 4, a specific embodiment of a method for invoking a vehicle-mounted camera according to the present invention is shown. The application program stores two types of device identifications, namely ID0 and ID 1; the vehicle-mounted system comprises a plurality of vehicle-mounted cameras, and one camera is actual equipment; the vehicle-mounted system is provided with a database and is connected with the application program.
Before a user calls a camera, virtual channels, namely virtual pipe, are created, and if the number of the actual devices is N, M devices are virtualized in the middle layer. Wherein N and M are positive integers, and M is more than or equal to N; the virtual pipe is buffer (cache) information, resolution information and frame rate information actually required by calling the vehicle-mounted camera, and is information of an actual device identifier to be remapped into the virtual device. And each virtual pipe is a description of one of the virtual devices. Corresponding to the virtual device. And determining the virtual pipe according to the virtual equipment identifier so as to establish a mapping relation between the virtual equipment identifier and the actual equipment identifier as a second mapping relation, generating a second mapping table according to the second mapping relation, and storing the second mapping table in a database of the vehicle-mounted system.
And establishing a second mapping relation between the virtual equipment identifier and the formal equipment identifier according to the user requirement, generating a first mapping table according to the first mapping relation, and storing the first mapping table into a database of the vehicle-mounted system. At this time, the formal device identifier is mapped to the virtual device identifier, which is equivalent to binding the formal device identifier with the virtual device identifier. And the virtual equipment identifier binds the actual equipment identifier according to the virtual pipe. I.e. a unique connection path is formed between the formal device identification and the actual device identification.
When the user opens the APP and selects the opened form equipment identification, the APP sends a calling request to the vehicle-mounted system, and the calling request comprises the form equipment identification selected by the user. And the vehicle-mounted system acquires the call request and reads the formal equipment identification in the call request.
Reading a first mapping table stored in a database, searching a first mapping relation including the formal equipment identifier from a preset first mapping relation, and determining a target virtual equipment identifier corresponding to the formal equipment identifier according to the first mapping relation.
And reading a second mapping table stored in the database, searching a second mapping relation including the target virtual equipment identifier from a preset second mapping relation, and determining a target actual equipment identifier corresponding to the formal equipment identifier according to the second mapping relation.
Because the actual equipment identification corresponds to the actual equipment one to one, when the target actual equipment identification is determined, the corresponding target vehicle-mounted camera can be determined according to the target actual equipment identification. At this time, the form equipment identifier can be determined to bind the target vehicle-mounted camera.
The vehicle-mounted system establishes a connection between the target vehicle-mounted camera and the application program, and the application program can send control operation or information to the target camera through the connection so that the application program calls the target camera.
According to the embodiment of the invention, the vehicle-mounted system is actively adapted to the application program, so that other cameras can be opened through the first mapping relation and the second mapping relation only under the condition that the application program only has ID0 and ID 1.
