The VDS shall be a single camera system compatible with different controller We support trip-line, tracking-based, and thermal image based video detection systems. Fire Detection . Video Detection System This specification sets forth the minimum requirements for a video detection system that detects vehicles, bicycles, and motorcycles on a roadway by processing video images and that provides vehicle presence, traffic flow data, event alarms, and full-motion video for real-time traffic control and management systems. The other check is that the area of the contour should be >= 25. Let’s take an example. Cost-effective Video detection systems for monitoring traffic streams are a very cost-efficient solution. The highlighted edges of the notepad are not visible anymore. There is still scope of improvement. Another possible way of processing video detection would be by applying state-of-the-art image detectors such as YOLOv3 or face detectors like RetinaFace and DSFD to every frame of a video file. Note that there are multiple highlighted regions and each region is encircled by a contour. Then we went on to build our own moving object detection system using OpenCV. As discussed earlier, taking the difference of the pixel values of two consecutive frames will help us observe the moving objects. This is how we will detect vehicles in all the frames. Passionate about learning and applying data science to solve real world problems. The immediate visual feedback received from a video detection system allows the traffic manager to assess what is happening and to take appropriate action. You can train a deep learning model for object detection or you can pick a pre-trained model and fine-tune it on your data.
