Referring to fig. 3, fig. 3 is a flowchart of an image processing method according to a second embodiment of the present invention.

Wherein one slave workstation processes one sub-image, i.e. there is a one-to-one correspondence between N sub-images and N slave workstations.
In one example, the image generation subsystem may specifically include more than 5 workstations, wherein 1 workstation is a master workstation and the other workstations are slave workstations.
The image data is made through the main workstation, the image segmentation logic is operated, the image operation command is pushed to each slave workstation after compiling, the N slave workstations operate respectively to generate the sub-images of the corresponding image range, and finally, a coherent high-definition lossless image can be formed through the sub-images generated by all the slave workstations, for example, a target image reaching the resolution of 12K.

The central control subsystem may transfer the sub-images to the image display subsystem via a number matrix.
S360: and respectively projecting the N sub-images onto a display unit by utilizing the N projection units so as to present a complete picture of the target image.
It should be noted that, in this process, the operator only needs to operate the master workstation all the time, and the specific operation process of the 12K high-definition lossless image is completed by the master workstation pushing the image to the slave workstation W, the slave workstation X, the slave workstation Y, and the slave workstation Z. The main workstation may be provided with a monitor (as shown in fig. 5) whose display screen and the screen projected to the display unit by the projection unit are always kept the same.
If the active stereo image needs to be displayed, each slave workstation can respectively output two paths of stereo left and right eye signals to the central control subsystem, wherein the two paths of stereo left and right eye signals refer to the stereo left and right eye signals of one sub-image.
Accordingly, the image display subsystem may include: an infrared stereo signal transmitting unit and active stereo glasses. After the infrared stereo signal transmitting unit receives the stereo left and right eye signals from the central control subsystem, the signals are sent to active stereo glasses capable of receiving stroboscopic signals, and finally the 12K high-definition lossless active stereo image can be displayed.
