A Computer Vision System Accurately Computes Real-Time Vehicle Velocities

Vision-Based Speed Detection Algorithms

There are at least two primary reasons why it is becoming more and more crucial to precisely estimate the speed of road vehicles. To start, there has been a noticeable uptick in the number of speed cameras deployed around the globe in recent years. This is likely due to the widespread belief that enforcing reasonable speed limits is a great way to make roads safer for everyone. In addition, smart cities rely heavily on traffic monitoring and forecasting in road networks to improve traffic, pollution, and energy consumption.

One of the most important metrics for traffic conditions is vehicle speed. There are a lot of obstacles to overcome with vision-based systems when it comes to accurate vehicle speed detection, but there are also a lot of potential benefits, like a significant drop in costs (because range sensors aren’t needed) and the ability to correctly identify vehicles.

Video camera input data is the foundation of vision-based speed detection algorithms. There will be a photo album starting with the initial reveal and ending with the final reveal for every car. Factors such as vehicle speed, focus length, frame rate, and camera orientation relative to the road determine the total number of usable photographs.

Features:

• Variously known as traffic surveillance cameras or traffic CCTV, traffic cameras record traffic events live. Automatic or manual (visible inspection by a human operator) traffic flow, congestion, and accident monitoring is possible with their help. These cameras are often infrastructure- or drone-based and set up at a distance from the flow of traffic.
• Cams that record vehicles’ speeds are often called traffic enforcement cameras. In common parlance, they are a tool for keeping tabs on cars’ speeds apart from the actual speed sensor (be it radar, laser, or vision). The word “camera” comes from the fact that any system that uses radar or lasers to capture images of the vehicle also uses a camera. The word “speed camera” is used here in its most basic sense, meaning systems that measure speed using vision. Compared to the traffic cameras, their placement is typically more advantageous.
