Specifically, when the LED screen corresponding to the LED screen position meets a preset specific gravity in the LED screen group position, it is determined that the second picture image meets the preset proportion adjustment requirement, and the preset specific gravity is determined according to the position of the LED screen, for example, when the LED screen is located in the first block and the second block in the LED screen group position, the specific gravity is smaller, that is, the specific gravity of the LED screen does not meet the preset specific gravity.
Specifically, when the second picture image is subjected to scale adjustment, the second picture image is only aimed at the LED screens at the positions of the LED screen groups with the abnormal positions.

step S101, denoising the first picture image and the second picture image, and performing image enhancement processing on the denoised first picture image and second picture image.
Specifically, noise can be understood as "a factor that hinders human sense organs from understanding the received source information". For example, if a black and white picture has a planar luminance distribution assumed to be f (x, y), then the luminance distribution R (x, y) interfering with its reception is referred to as image noise. Common image noise is additive noise, multiplicative noise, quantization noise, and "salt and pepper" noise. Additive vocal and image signal intensity are uncorrelated, for example: the television camera of "channel noise" that the picture introduces in the transmission process scans the noise of the picture; the vocal and image signals are correlated and tend to vary with changes in the image signal, such as: voice in flying spot scan images, television scan raster, film grain, etc.; quantization noise is the main noise source of digital images, and the size of the quantization noise shows the difference between the digital image and the original image; "salt and pepper" noise, for example: white spots on a black image, black spot noise on a white image, errors introduced in a transform domain, and transform noise caused by inverse image transformation.

Generally, the measurement precision is higher. The thermometer can also measure the temperature distribution inside the object within a certain temperature measuring range.
Specifically, when signal source connection data of the LED screen is monitored, the signal source connection data can be obtained by obtaining a data transmission rate of a signal line connected to the LED screen.
Step S15, determine whether the real-time status data exceeds the normal threshold of the LED screen.

In step S16, if the result exceeds the predetermined threshold, the state warning information is generated and the display of the state warning information is controlled.
