Auto Tracking 3.0 is an AI-powered tracking algorithm by Dahua for the company’s PTZ system. When a target triggers the IVS rule, the camera uses its horizontal/vertical rotation and zoom features to lock the moving target in the centre of the screen. The whole tracking process is stable, clear and smooth.
The new Auto Tracking 3.0 has upgraded a variety of AI technologies based on the 2.0 algorithm, including PFA 3.0, speed-adaptive algorithm, position-adaptive algorithm and the filtering interference algorithm. The tracking performance is further improved in all three areas that customers focus on, such as multiple target types, clear details and accurate tracking.
Through training on a large number of target images, the upgraded Auto Tracking 3.0 offers optimised tracking of four types of targets. In addition to human, ship and vehicle targets, it also provides aircraft tracking through customised firmware.
The PFA 3.0 focusing technology realises deep integration of intelligent algorithms and focusing algorithms, effectively improving the focusing output during tracking and capturing, delivering smooth focus.
The speed-adaptive algorithm can adjust the speed of the PTZ camera’s rotation, zoom and image exposure according to the target’s speed, making the whole tracking process continuous, smooth and without sudden changes, even when the target is a fast-moving car.
The position-adaptive algorithm merges deep learning-based target detection technology and 3D positioning technology, keeping the target in the centre of the image with the right proportion, while zooming in or out.
The new DPT technology can calculate the tracking target frame more accurately. It is capable of tracking smaller targets and further improving the tracking distance, which could reach 1500 metres in ideal conditions. In other words, as long as the target is within the monitoring range, the PTZ cameras are able to track its complete movement with high accuracy.
The interference filtering algorithm can accurately estimate the moving direction, step size and speed of the target according to the characteristics of the target motion vector. The target can be tracked continuously, even in complex scenes with occlusion, interlacing, light changes, etc.
Some application scenarios
In nature reserves, 4G active deterrence PTZ cameras are used to patrol large areas. Warning lights and sounds will be triggered to drive away intruders. What’s more, it provides detailed features and traces of intruders for follow-up search and rescue.
In airports, PTZ cameras that adopt the Auto Tracking 3.0 algorithm are installed to track the departure and landing of aircraft for aviation safety. The landing gear is closely monitored to ensure normal functioning.
In watercourses, cameras can track ships to help the operator see the ship number and make ship management easier. In addition, the PTZ cameras can detect water levels and raise an alarm when they detect floating objects.
Dahua always focuses on innovating new technologies to upgrade the user experience and provide smarter solutions for clients in various industries. It will adhere to its mission of ‘enabling a safer society and smarter living.’
