Vision AI has revolutionized video content analysis or VCA by enabling automated, accurate, and efficient extraction of meaningful information from videos. It’s a very effective technology to gather important traffic data for urban planning, traffic management, and transportation optimization.
Using computer vision AI models and algorithms we can analyze real time video streams captured by cameras placed at strategic locations in urban areas. To understand the process first we have to understand what VCA is.
What is Video Content Analysis(VCA)
Video content analysis or VCA or video analytics is the process of using computer vision algorithms and artificial intelligence models to automatically analyze and understand the content within video footage and extract meaningful information, patterns, and insights from video data, enabling various applications and functionalities. VCA systems can detect objects, people, vehicles, track their movement, identify unusual actions, and provide real-time alerts and insights.
How it is Used in Vehicle Counting
Using AI to automate vehicle counting in urban traffic through video content analysis is an effective way to gather important traffic data for urban planning, traffic management, and transportation optimization.To this we have to follow the below process
Data Collection and Storage: To count vehicles first we have to collect data from various installed cameras at key locations across the urban area to capture video footage of traffic. These cameras must cover intersections, road segments, and other relevant points to get a comprehensive view of traffic flow. Captured video footage needs to be stored and organized for analysis. This might involve creating an efficient system to manage the video storage.
Preprocessing: Raw video footage may contain a lot of irrelevant information and noise. Preprocessing involves tasks like stabilizing the video, adjusting lighting conditions, and removing any unnecessary information that could interfere with analysis.
Annotation: Data labeling and annotation is a crucial step in developing machine learning models, especially in computer vision tasks like vehicle counting. This process involves manually tagging and labeling the relevant information in your dataset so that the model can learn from it.
Model Training: Model training is a crucial step in developing an AI system for vehicle counting through video content analysis. It involves using a machine learning algorithm, typically a convolutional neural network (CNN) in computer vision tasks, to learn patterns and features from your labeled dataset.
Vehicle Counting: Now apply the trained model to the entire video dataset. As the model processes each frame, it detects and counts the vehicles present, accumulating the count over time. This count can be stored in a database to use in various cases.
It’s important to note that while AI-based vehicle counting can be highly accurate, it still might encounter challenges in complex scenarios. Regular updates and improvements to the AI model will be necessary to adapt to changing conditions and ensure consistent accuracy.
