A Driver (Device Driver) is a special program that enables a computer to communicate with a Device, and is equivalent to a hardware interface, and an operating system can only control the operation of the hardware Device through the interface, and cannot operate normally if the Driver of a Device is not installed correctly.
For this reason, the driver is important in the system, and generally, when the operating system is installed, the driver for installing the hardware device is the first to install. However, in most cases, drivers for all hardware devices are not required to be installed, for example, a hard disk, a display, an optical drive, etc. are not required to be installed, and a video card, a sound card, a scanner, a camera, a Modem, etc. are required to be installed. In addition, the operating systems of different versions support hardware devices differently, and generally, the higher the version is, the more hardware devices are supported, for example, a writer uses Windows XP, and a driver after the system is installed does not need to be installed.

and the area analysis equipment is connected with the full-color camera and used for receiving the full-color shot image and carrying out contour extraction on each target in the full-color shot image so as to obtain each distribution area of each target in the full-color shot image.
The field indicator lamp driving mechanism can further comprise:
and the region partitioning device is connected with the region analysis device and is used for partitioning the full-color shot image to obtain each sub-image, wherein the size of the sub-image obtained by uniformly dividing each distribution region in the full-color shot image is smaller than that of the sub-image obtained by uniformly dividing the non-distribution region.
The field indicator lamp driving mechanism can further comprise:
and the dynamic range detection device is connected with the area partitioning device and used for receiving each sub-image of the full-color shooting image, detecting the dynamic range of each sub-image, and adjusting the threshold size of the corresponding sub-image for background stripping based on the width size of the dynamic range of each sub-image.
The field indicator lamp driving mechanism can further comprise:

and the foreground analysis equipment is also used for integrating the foreground areas corresponding to the sub-images to obtain a foreground image and outputting the foreground image.
The field indicator lamp driving mechanism can further comprise:

In the site indicator lamp driving mechanism:
in the region blocking apparatus, uniformly dividing each distribution region includes: the larger the area of the distribution region, the larger the size of the sub-image obtained by the division.
In the site indicator lamp driving mechanism:
in the dynamic range detection apparatus, adjusting the threshold size for peeling the background of the corresponding sub-image based on the width size of the dynamic range thereof includes: the larger the width of its dynamic range, the larger the adjusted threshold for background stripping of the corresponding sub-image.
In addition, image filtering, namely, suppressing the noise of the target image under the condition of keeping the detail features of the image as much as possible, is an indispensable operation in image preprocessing, and the effectiveness and reliability of subsequent image processing and analysis are directly affected by the quality of the processing effect.
Due to the imperfections of the imaging system, the transmission medium, and the recording device, the digital images are often contaminated by various noises during the formation, transmission, and recording processes thereof. In addition, noise may also be introduced into the resulting image at some point in the image processing when the input image object is not as expected. These noises often appear as an isolated pixel or block of pixels on the image that causes a strong visual effect. In general, the noise signal is not correlated with the object to be studied-it appears in the form of useless information, disturbing the observable information of the image. For digital image signals, the noise table is more or less extreme values, and the extreme values act on the real gray values of image pixels through addition and subtraction to cause bright and dark point interference on the image, so that the image quality is greatly reduced, and the follow-up work of image restoration, segmentation, feature extraction, image identification and the like is influenced. Two basic issues must be considered to construct an effective noise suppression filter: the noise in the target and the background can be effectively removed; meanwhile, the shape, the size and the specific geometric and topological structure characteristics of the image target can be well protected.
One of the commonly used modes of image filtering is a non-linear filter, generally speaking, when the signal spectrum is mixed with the noise spectrum or when the signal contains non-superimposed noise, such as noise caused by system nonlinearity or non-gaussian noise, etc., the conventional linear filtering techniques, such as fourier transform, always blur the image details in some way while filtering the noise, thereby causing the positioning accuracy of the image linear features and the extractability of the features to be reduced. The nonlinear filter is based on a nonlinear mapping relation of an input signal, a specific noise can be mapped to be zero approximately, the main characteristic of the signal is reserved, and therefore the nonlinear filter can overcome the defects of the linear filter to a certain extent.
