The application of SONY FCB-EV7520 optical zoom in UAV aerial photography

SONY FCB-EV7520 is equipped with a 30x optical zoom lens, which can be widely used in security monitoring, intelligent transportation, unmanned aerial vehicles, detection equipment and video conferencing, and can be the most realistic magnification of the image machine close to the subject, and the clarity and resolution of the picture without any damage.

Xuan Zhan Technology (SONY’s official authorized distributor) will tell you about the application of SONY FCB-EV7520 optical zoom in UAV aerial photography:

1. What is camera zoom?

Let’s start with the basics. In photography, the zoom of a camera refers to making an object appear closer or further away in an image. Zooming in allows us to photograph the object at a closer distance, while zooming out allows us to photograph a wider space.

2. Definition of optical zoom

Optical zoom is an effect achieved using a series of lens elements that can be zoomed in or out by lens movement. Optical zoom can provide better zoom results and is the most realistic method of image magnification. Because images are magnified and reduced by controlling the light in the scene, optical zoom does not compromise the clarity and resolution of the picture.

Optical zoom effect comparison of different multiples

Optical zoom can provide the same picture and effect as the most realistic close to the subject of the shot. Of course, this is only a theoretical principle, the quality of the lens will affect the optical zoom effect, and depending on the different lens and aperture, it can also gradually decrease with the increase of the focal length.

3. Application of FCB-EV7520 optical zoom

The selection of camera in UAV aerial photography is very important. In many applications, we often need to use optical zoom to zoom in and observe objects in order to see the details of objects, such as public security duty, power line patrol, fire and disaster relief, target search and other UAV aerial photography application industries. It’s the camera’s optical zoom technology that allows us to control the drone at high altitude to see far and near, to see the whole and to see the details.

How to achieve remote control of high-altitude UAV zoom precise control problem, has been considered by engineers, different from the past DV and micro SLR camera to achieve the way, 30x optical zoom, powerful image imager to make SONY FCB-EV7520 HD digital movement more and more popular. Now we can command the way in which large-fold optical zoom and high-definition video stream output are delivered.

4. Uav aerial video output scheme

FCB-EV7520 HD movement solution solves the zoom control of the UAV airborne camera, but the image compression and transmission after the output HD stream needs to be developed separately, which will be extremely complex for UAV companies. The above problems can be easily solved by the coding control board of Shenzhen Xuanzhan Technology Co., LTD. Xuanzhan Technology specially develops coding control board and video acquisition, output and transmission technology solutions for SONY HD movement. In addition, it also develops SDI mini coding control board for UAV, which is smaller in size and lighter in weight, and more convenient for UAV aerial photography.

In addition to SONY FCB-EV7520, due to the particularity of UAV applications, the compact and lightweight FCB-EV7100 with optical zoom of 10 times is also a good choice.
