Determine the third personnel density according to the personnel count information.

[0069] Specifically, during implementation, the control server compares the personnel monitoring image with the preset background template image of the target exhibition area (the background template image is the background image when there are no personnel in the target exhibition area) to determine the foreground area and the corresponding personnel area in the personnel monitoring image. Then, the image area of the foreground area is divided by the image area of the personnel monitoring image to obtain the first area ratio, and the first area ratio is multiplied by the set first density coefficient to obtain the first personnel density. The control server takes the pixel area in the infrared thermal image corresponding to the detected temperature within the set temperature range (i.e., the pixel area with color or gray value within the set interval) as the personnel image area. Then, the image area of the personnel image area is divided by the image area of the infrared thermal image to obtain the second area ratio, and the second area ratio is multiplied by the set second density coefficient to obtain the second personnel density.
