With the advancement of wireless video transmission technology, drone aerial photography is no longer performing high-altitude viewing of video and pictures. It is already possible to implement real-time wireless image transmission. As a result, drone aerial photography has been widely used in urban planning, ecological research, film and television aerial photography, major events, live events, and wedding photography. Viewing the shooting results after no one returns to real-time transmission is mainly a result of the drone wireless image transmission system improving the results. The following is a detailed description of this system for everyone.
The UAV wireless image transmission system is to send the picture taken by the drone in flight in the sky to the terrestrial wireless image transmission remote control receiving device in real time. The real-time nature of image transmission and its components are mainly composed of the transmitter, receiver, and display.
UAV aerial photography application in many fields
COFDM HD low latency 1080P wireless image transmission system is the mainstream
COFDM high-definition low-delay 1080P wireless image transmission system is the current advanced image transmission technology. System equipment uses SDI or HDMI interface as the input and output interface of high-definition images. Can support 1080P wireless transmission and downward compatible with 720P, 480P and SD picture quality.
The system components equipment power can be 0.5-30W equipment according to the specific situation. According to the equipment frequency and power size, a monitoring system with different distances is produced. Usually between 0.5W and 1W for small transmitter reception, more suitable for aerial image transmission. Between 2W-5W is a single soldier piggyback device. This is also a product with more COFDM applications. It covers a wide range of applications including firefighting, security patrols, and field patrols. The 5W-30W is an on-board device. The device is bulky and is usually installed on a patrol car or in a fixed place. Three types of COFDM equipment can be arbitrarily networked into long-distance wireless image transmission systems.
Vision Crystal Wireless UAV aerial wireless transmitter
System Overview:
1. Equipment frequency: The equipment uses 300-900MHZ low frequency transmission, equipment penetration ability, small delay
2. COFDM adopts highly integrated design. The system not only has the smallest volume and weight equipment in the industry, but also has individual backpack and vehicle-mounted equipment. Demand for full-HD digital image transmission that meets different requirements such as volume and weight. Such as: aviation shooting, live television, temporary scene monitoring, cultural activities, vehicle patrol monitoring and other projects
3. High-efficiency compression of H.264 new digital video coding standard enables ideal image compression at the lowest code rate
4. The use of COFDM, 2K subcarriers, QPSK and 16QAM coded modulation methods to effectively improve spectrum utilization
5. Modulation bandwidth: 2/4/6/8MHz
6. The system's maximum effective RF output power up to 30W, can be customized according to the specific needs of customers
7. System delay 150ms-300ms range, can be said to achieve high-definition low-latency transmission
The COFDM wireless image transmission system can be configured with different devices according to different project conditions, and can also extend relay transmission distance. The system uses a lot of fields such as aerial image transmission of drones, fire monitoring, accident patrols, and smart and safe cities.
