An image information processing method includes obtaining, by an AR device, a first image including an image of a target object. The method includes detecting an environmental parameter of the AR device based on the first image. The method includes determining a cropping ratio coefficient of the first image based on the environmental parameter. The method includes cropping the first image based on the cropping ratio coefficient, to obtain a second image. The method includes extracting M contour feature points in a remaining image of the target object from the second image, to generate an AR image of the target object. The method includes displaying the AR image on a front windshield of a car.

A mobile network access device, system and method are disclosed. The method includes sending data or a command to a storing unit or a baseband processing unit according to a logical address in a Secure Digital (SD) command, where the SD command is a result of converting a Small Computer System Interface (SCSI) Command Descriptor Block (CDB) after a terminal device encapsulates the received data or command into the SCSI CDB. In the embodiments of the present invention, the wireless Internet access function is integrated into an SD card. The mobile network access device determines to send the data or command to the baseband processing unit or storing unit according to the logical address in the SD command, which reduces the size of the mobile network access device and enables developers to design smaller terminal products.
