During the construction of fine pixel pitch LED screens, there is a common occurrence of dark or bright lines appearing between adjacent modules. These lines are caused by the dislocation of panels during installation and can have a significant impact on the overall visual experience. Manual calibration and professional camera calibration are the two methods that are typically used for calibration; however, both of these approaches have limitations. Professional camera calibration equipment is expensive and awkward to carry; and the systems are often quite complex, and it is challenging for staff to operate them. While manual calibration relies on human eye observation, the efficiency is limited, and the quality cannot be controlled.
To deal with these issues, AOTO has developed an intelligent correction system that can be used with a mobile phone for smaller, easily accessible screen installations, or a drone for larger exterior screens at a concert or festival stage, as well as for large advertising screens on buildings to easily eliminate dark or bright lines of an LED display. This system is intended to replace manual inspection and cameras that enable gap calibration. After installation, there are no complicated steps; instead, users only need to use a smartphone running the app, or drone, to scan the screen, which will then automatically accomplish the system configuration and then complete the debugging of the image.
The correction system uses advanced AI image processing technology, and a single scan can correct multiple lines, increasing the efficiency by more than six times. The system adopts wireless networking technology, allowing multiple mobile phones to calibrate at the same time, and completing the assembly and on-site calibration of the display quickly. The system is simple, clever, and extremely effective; it has been utilized in a variety of projects, where it has contributed to a significant increase in installation speed and a reduction in overall project duration. After the correction, the picture quality is significantly improved. The effect is very remarkable.
At the InfoComm show 2022 in Las Vegas, AOTO introduced this groundbreaking new and upgraded system—Intelligent UAV / Smartphone Calibration System, which can be used with a mobile phone, or drone, to easily eliminate dark or bright lines of an LED display. This brings the efficiency and capability of calibration to an entirely new level.
It was developed for the application of larger-sized display screens at height such as outdoor advertising and large-scale concerts. All you have to do is to fly the drone close to the display screen in order to get to the right position and complete the systematic configuration. This method is not constrained by the height of the screen, is not impacted by the surrounding environment, and can deal with any tricky angles. The scanning and processing range is significantly larger than that of a mobile phone (more than four times as large), and the effect is significantly enhanced.
In addition to the powerful calibration function, the components of the Intelligent UAV / Smartphone Calibration System are wirelessly connected, making it very easy to use. The system supports real-time preview of onboard images, and supports real-time monitoring of drone status, attitude, remote control communication connection, remaining battery power, remaining flight time, and other information to ensure that all calibration work is carried out smoothly.
