The algorithm deployment scheme of the non-coal mine electronic seal system is based on the python+opencv network model Ai video image recognition technology. The non-coal mine electronic seal system algorithm deployment scheme detects the conditions of personnel entering and exiting the well, personnel changes, and production and operation status of non-coal mines in a timely manner. Processing abnormal dynamics will automatically send out alerts. The full name of OpenCV is Open Source Computer Vision Library, which is a cross-platform open source software library for computer vision processing. It is initiated, participated and maintained by the Russian team of Intel Corporation. It supports many algorithms related to computer vision and machine learning, with BSD license Released under license, free for commercial and research use. OpenCV can be used to develop real-time image processing, computer vision and pattern recognition programs, and the library can also use Intel's IPP for accelerated processing.
OpenCV is implemented based on C++ and provides interfaces for languages such as python, Ruby, and Matlab. OpenCV-Python is OpenCV's Python API, which combines the best features of OpenCV C++ API and Python language. Python is slow compared to languages like C/C++. That said, Python can be easily extended using C/C++, which allows us to write computationally intensive code in C/C++ and create Python wrappers that can be used as Python modules. This gives us two benefits: first, the code is as fast as raw C/C++ code (since it's actual C++ code working behind the scenes), and second, it's easier to write code in Python than in C/C++. OpenCV-Python is a Python wrapper around the original OpenCV C++ implementation.
OpenCV is available on different system platforms including Windows, Linux, OS, X, Android and iOS. High-speed GPU operation interfaces based on CUDA and OpenCL are also under active development. Perfect traditional computer vision algorithms, covering mainstream machine learning algorithms, while adding support for deep learning. Python is a general-purpose programming language developed by Guido van Rossum, which quickly became very popular mainly because of its simplicity and code readability. It enables programmers to express ideas in fewer lines of code without loss of readability. OpenCV-Python uses Numpy, a highly optimized database manipulation library with MATLAB-style syntax. All OpenCV array structures are converted to Numpy arrays. This also makes it easier to integrate with other libraries that use Numpy, such as SciPy and Matplotlib.
The Adapter interface defines the following methods:
public abstract void registerDataSetObserver (DataSetObserver observer)
Adapter represents a data source. This data source may change, such as adding data, deleting data, and modifying data. When the data changes, it must notify the corresponding AdapterView to make corresponding changes. In order to realize this function, the Adapter uses the observer mode. The Adapter itself is equivalent to the observed object, and the AdapterView is equivalent to the observer. Register the observer for the Adapter by calling the registerDataSetObserver method.
public abstract void unregisterDataSetObserver (DataSetObserver observer)
Unregister the observer by calling the unregisterDataSetObserver method.
public abstract int getCount () returns the number of data in the Adapter.
public abstract Object getItem (int position)
The data in the Adapter is similar to an array, and each item in it corresponds to a piece of data, and each piece of data has an index position, that is, position, and the corresponding data item in the Adapter can be obtained according to the position.
public abstract long getItemId (int position)
Get the id of the specified position data item, usually the position will be used as the id. In Adapter, relatively speaking, position is used more frequently than id.
public abstract boolean hasStableIds ()
hasStableIds indicates whether the id of the original data item will change when the data source changes. If it returns true, it means the Id remains unchanged, and if it returns false, it means it may change. The hasStableIds method of Adapter subclasses (including direct subclasses and indirect subclasses) provided by Android all return false.
public abstract View getView (int position, View convertView, ViewGroup parent)
getView is a very important method in Adapter, which will create corresponding UI items for AdapterView according to the index of the data item.
