FDG4 is a cost-effective full-frame, high-pixel tilt camera that can be adapted to most rotary-wing/fixed-wing drones on the market. The camera adopts a mature general-purpose optical module on the market, with a total pixel of 210 million, with a 40/56mm focal length lens, full-frame cmos, not only suitable for traditional projects, but also for front-end data collection of real-world 3D smart city projects.
1:1.5 oblique ortho focal length ratio
The focal length of most oblique photography cameras on the market is 25/35mm, which cannot meet the needs of smart city modeling. FDG4 adopts the focal length of the ortho-optical lens of 40mm and the focal length of the oblique optical lens of 56mm to meet the modeling needs of urban high-rise areas. At the same time, when the building height is high, it also faces the problem of UAV flight attitude disturbance caused by high-altitude wind. FDG4 adopts a 1:1.5 inclined orthophoto focal length ratio, which can ensure that the image resolution of the five cameras of the camera is basically the same, and improve the air-to-three pass rate. rate and model accuracy.
Extra Low Dispersion Aspherical Lenses
Optical lens is the key component of aerial survey camera and the decisive factor of aerial image quality. Each group of FDG4 lenses has a built-in ultra-low dispersion aspherical lens, which controls the overall distortion of the optical lens to less than 4/1,000. Three stratified probability.
Self-contained all-in-one storage module
The camera is equipped with an independent detachable storage module, and the memory is 320GB/640GB. Replaceable storage modules can avoid wasting time in the field due to data copying and improve field efficiency. The copy speed of the fast storage module can reach 300MB/s, which can greatly reduce the time for data sorting and improve the efficiency of the office.
full frame CMOS
A larger frame can bring better latitude and high sense, and a full-frame lens can easily capture the details of object texture features at a higher altitude; when flying in high-density high-rise buildings, more buildings can be captured. When splicing models in the industry, more elevation information of tall buildings can be obtained to achieve better modeling effects.
Suitable for modeling high-rise areas
FDG4M has excellent data collection in the high-rise area, and the established high-rise model has good effect and high accuracy. FDG4M adopts more excellent image algorithm, which can ensure the effect of high-rise area model from the aspects of image calculation and matching of points with the same name.
Data preprocessing software
FDG4 comes with a data preprocessing software. Its function is to preprocess the data obtained after the tilting camera completes the acquisition task. Through the CONECT UNIT unit, it can automatically calculate the attitude information of each camera, and directly generate the blocks file, which not only improves the The success rate of air threes can also reduce the number of air threes and improve the efficiency of puncture points by more than 50%.
Route planning software
The FDG4 route planning software can automatically expand and generate corresponding routes according to the survey area and altitude, and has a series of practical functions such as KML files, one-key import of 3D models, intelligent survey area segmentation, and flight information statistics. There are four types of routes: circular, imitation ground, and elevation, to meet various flight tasks and application needs, and to create a convenient and intelligent route planning platform for users.
