Description
Technical Field
The invention relates to the field of monitoring equipment, in particular to a platform and a method for locking associated personnel based on instruction signal triggering.
Background
The monitoring equipment is a general name of equipment used in the installation construction and technical realization of a monitoring system. The monitoring system mainly comprises a camera part, a transmission part, a control and recording part and a display part.
The camera part is the leading edge part of the television monitoring system and is the "eye" of the whole system. When the area of the monitored place is larger, a zoom lens is additionally arranged on the camera, so that the distance which can be observed by the camera is farther and clearer; still can install the camera on electronic cloud platform, can make the cloud platform drive the camera and carry out the rotation of level and vertical direction to the angle that makes the camera function cover is bigger.
In some cases, especially in outdoor applications, special protective covers should be added to the cameras and their lenses for dust prevention, rain protection, high and low temperature resistance, corrosion resistance, etc., and even corresponding protective measures should be taken for the pan-tilt.
The transmission part is the image signal path of the system. Generally, the transmission section refers to transmission of image and audio signals. Meanwhile, a control center is needed to control the camera, the lens, the pan-tilt and the like through a control console, so that the transmission system also comprises transmission of control signals. In the transmission mode, video line transmission is generally adopted at a short distance, twisted pair transmission is generally adopted at a distance not exceeding one kilometer or two kilometers, and optical fiber transmission can be adopted at a longer distance. For long-distance transmission, video signal amplification, image signal correction and compensation equipment are also required.
The control and recording part is responsible for controlling the camera and auxiliary components (such as a lens and a holder) thereof and recording images and sound signals. The technology of the current hard disk video recorder is developed more perfectly, the hard disk video recorder not only can record images and sound, but also has the functions of picture segmentation switching, pan-tilt-lens control and the like, and basically replaces the products of the picture switcher, the picture splitter, the pan-tilt-lens controller, the lens controller and the like which are used in the past. If the customer requires to control the holder and lens (especially high speed ball) conveniently, a control keyboard can be added.
The display section is generally composed of several or more monitors. Under the condition that the number of the cameras is not large and the requirement is not high, the monitor can be directly connected to the hard disk video recorder. If the number of cameras is large and a plurality of monitors are required to perform complicated switching display on pictures, the method needs to be implemented by a matrix.

Detailed Description
Embodiments of the instruction signal trigger based associated personnel locking platform and method of the present invention will be described in detail below.
Data (Data) is a representation of facts, concepts or instructions that can be processed by either manual or automated means. After the data is interpreted and given a certain meaning, it becomes information. Data processing (data processing) is the collection, storage, retrieval, processing, transformation, and transmission of data.

The development of data processing technology and the breadth and depth of its application have greatly influenced the progress of human society development.
At present, when an object scanner is used for detecting the danger degree of people carrying objects, once dangerous objects are detected, due to the fact that a person association mechanism is not established on site, the event that related people escape easily occurs, and subsequent troubleshooting cannot be smoothly performed, and therefore the site associated people need to be locked in time when the object scanner detects the dangerous objects.
In order to overcome the defects, the invention builds the platform and the method for locking the related personnel based on the instruction signal triggering, and can effectively solve the corresponding technical problems.

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 image filtering modes is a non-linear filter, generally speaking, when the signal spectrum and the noise spectrum are mixed or when the signal contains non-superimposed noise, such as noise caused by system nonlinearity or the presence of non-gaussian noise, etc.), the conventional linear filtering techniques, such as fourier transform, while filtering out noise, always blur the image details (such as edges, etc.) in some way, 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.
