Is the world's leading research and development and manufacturer of UAV control systems and UAV solutions, with customers all over the world 100 countries. Through continuous innovation, DJI is committed to providing revolutionary intelligent flight control products and solutions with the strongest performance and best experience for UAV industry, industry users and professional aerial photography applications.
Optical bridge technology is a unique secret of DJI, and it is also the core weapon to open the gap with other UAV brands. It can be said that in the image transmission system, DJI has left its competitors far behind.
Let's take a brief look at the results first. Models including Elf 3, 4 and Inspire Wu all use optical bridge image transmission. Under normal circumstances, the drone can clearly send the camera image back to the monitor with 720P resolution within 2 kilometers, while the general WiFi image transmission is nominally the longest distance of 500m, but it can only be completed within 50-200m without delay.
Although Lightbridge can't realize 100% image transmission without delay, it is still the most advanced image transmission system according to the actual operation at this stage. This is also the basis of DJI's safety performance guarantee in the field of drones.
. At present, the latest second generation technology of Lightbridge2 has been released, which can improve the definition of image transmission from 720P to 1080P in real time, and is more suitable for live broadcast and other applications.
Thanks to the optical bridge technology, the actual controllable flight distance of DJI UAV is generally 3-4 times larger than that of UAV using WiFi, and stable image transmission is an important foundation for professional applications such as aerial photography. From this perspective, those drones that transmit through WiFi can only be counted as toys.
