Why do industrial drones use high-power optical zoom pods?
In the working environment of industrial drones, the biggest challenge is to observe as close as possible to the target while maintaining a certain safe distance. The emergence of high-power zoom pods can provide clear aerial images for rear engineers in various scenarios such as public security firefighting, power inspection, traffic monitoring, etc., to complete tasks faster, safer, and more covert. The advantages of this long-distance image acquisition are obvious:

One is to stay away from the shooting target, avoiding interference from electromagnetic, fire and other factors on the drone;


The second is to avoid drones being too close to shooting targets such as crowds and causing danger to them;


The third is to prevent drones from encountering obstacles in complex working environments and causing explosions.


What can give drones such a "visionary" vision is not black technology, but a 30x optical zoom pod.


Can you distinguish the difference between gimbal and pod very well? As the trend of consumer grade drones gradually fades away, industrial drones are in a period of rapid development. For industrial drones, they actually pay more attention to drone system solutions, and the application field of industrial drone systems is determined by their mission equipment. Optical zoom pod is a type of unmanned aerial vehicle (UAV) mission equipment that has the functions of zoom photography and videography. Using UAVs as flight platforms, it can achieve all-weather tracking, videography, and monitoring of distant targets. It is the core equipment for UAV firefighting, reconnaissance, and patrol. Currently, the industry is vigorously developing optical zoom pods.


However, many people are not clear about the conceptual difference between a gimbal and a pod. A gimbal has been used in the photography industry as a support device for installing and fixing cameras. It can adjust the camera's horizontal, pitch, direction, and other angles in order to allow photographers to choose the appropriate angle to shoot. And pods are developed from the concept of aviation, referring to streamlined short cabin segments installed with onboard equipment or weapons and suspended under the fuselage or wings. Simply put, in the field of industrial drones, the most basic shooting pod is composed of professional camera equipment and high-precision stabilization gimbals.

Our BGT-30 is equipped with a 30x optical zoom lens and a 1/2.8 "SONY CMOS sensor, which can clearly present the details of scenery from hundreds of meters away to the user's eyes. The 5.5mm-180mm equivalent focal length lens can easily switch between wide-angle and telephoto, with a total pixel size of 2.07 million for capturing high-definition images. When detecting towers and wind turbines, the aircraft does not need to approach the equipment, and can observe and record equipment details from a distance. This means that BGT-30 not only improves detection efficiency, reduces operational difficulty, but also avoids potential collision accidents, making detection work safer.

If the previous generation of camera manufacturers were engaged in a "pixel battle," then in this generation, camera manufacturers are fighting on the "anti shake battlefield.". Because resolutions of 2k, 4k, and even higher are no longer significant for ordinary consumers. How to achieve better imaging quality within a limited number of pixels is what consumers are most concerned about. UnionTech has put higher demands on itself in terms of "anti shake". The BGT-30 is equipped with a three-axis pan tilt stabilization system and electronic anti shake. The camera shake is controlled within 0.01 °, ensuring clear and stable images while zooming in at high magnification. The three-axis stabilization gimbal not only significantly reduces jitter, but also compensates for changes in the aircraft's attitude, keeping the camera level and capturing stable and smooth images during high-speed motion. In addition, traditional zoom cameras can only enlarge the central area of the picture. When zooming at high magnification, the subject needs to be placed in the center of the picture first, otherwise the target may be lost during zooming.


BGT-30 extends advanced features such as image tracking, making it easy to control the image. In different application environments such as bridge and tower detection, real-time road condition monitoring, suspected target tracking and paving, and conventional line patrol, it can safely and effectively capture clear details from a long distance.


With the wider and deeper application of industrial drones, ordinary consumers have put forward high requirements for camera stabilization, let alone drones that need to be equipped with cameras to complete difficult tasks. During the operation of an aircraft, it is affected by airflow and high-speed motor propellers, resulting in low-frequency or high-frequency vibrations of various frequency amplitudes. Under the shooting of high-power optical zoom pods, these vibrations will be reflected in the distortion and shaking of the image, resulting in the inability to view or perform post-processing on the captured image.


So how does the high-power optical zoom pod achieve stability enhancement? Most drones achieve basic control of the aircraft by rotating around the XYZ three axes, namely direction, roll, and pitch. For the gimbal, the same applies. It consists of an IMU feedback system consisting of a three-axis gyroscope and a three-axis acceleration sensor, a servo motor control system, and a damping suspension, which filters out high-frequency vibrations. Therefore, the optical zoom pod with enhanced stability gimbal can still capture stable images during aircraft motion.


In this "anti shake battlefield" of high magnification optical zoom without gunpowder, in summary, a safe, operable, and intelligent flight platform; High precision, high stability, and high-quality imaging systems are the two core areas of competition. The future development of domestic drone technology is a key focus, which includes the adaptability of task equipment, high-definition video transmission capability, and the safety and reliability of drone operations. The high-performance 30x zoom pod will enable greater development in the drone industry applications.
