UAV aerial photogrammetry

Elf phantom 4 RTK

Take in everything in a glance.

Fairy Phantom 4 RTK is a small multi-rotor high-precision aerial survey UAV for low-altitude photogrammetry applications. It has centimeter-level navigation and positioning system and high-performance imaging system, which is portable and easy to use, and comprehensively improves the efficiency of aerial survey.

A new era of aerial survey

The system has been fully upgraded, and the aerial survey accuracy has been upgraded to a new standard, bringing users centimeter-level accurate data. At the same time, it greatly reduces the ground control points required by traditional aerial survey, simplifies the operation process and reduces the time cost.

* Flying in a sunny environment, the wind speed is less than 4 m/s, the flying altitude is 100 m, the ground sampling distance (GSD) GSD)2.74 cm, the heading overlap rate is 80%, and the lateral overlap rate is 70%.

Centimeter positioning system

Phantom 4 RTK integrates a brand-new RTK module, which has stronger anti-magnetic interference ability and accurate positioning ability, provides real-time centimeter-level positioning data, and significantly improves the absolute accuracy of image metadata. Support PPK postprocessing. The aircraft continuously records the original observation data of satellites, camera exposure files and other data. After the operation is completed, users can directly calculate high-precision location information through DJI cloud PPK service. The positioning system supports D-RTK 2 high-precision GNSS mobile station connection, and can be connected with NTRIP through 4G wireless network card or WiFi hotspot.

Time synchronous accurate data acquisition

In order to cooperate with Phantom 4 RTK positioning module, a new TimeSync system came into being. The synchronization of flight control, camera and RTK clock system is in microsecond level, and the imaging time error of camera is in millisecond level. The optical center position of the camera lens and the center position of the RTK antenna are compensated to reduce the time error between the position information and the camera and provide more accurate position information for the image.

High precision imaging

1 inch 20 megapixel CMOS sensor shoots high-definition images. The mechanical shutter supports high-speed flight shooting, which eliminates the jelly effect and effectively avoids the reduction of drawing accuracy. With the help of high-resolution images, the ground sampling distance (GSD) of Phantom 4 RTK can reach 2.74 cm at the flying height of 100 meters. Each camera lens has undergone strict process correction to ensure high-precision imaging. Distortion data is stored in the metadata of each photo, which is convenient for users to use post-processing software to make targeted adjustments.

Born for aerial survey

Phantom 4 RTK optimizes aerial photogrammetry in an all-round way, and the image control-free technology brings the results of surveying and mapping accuracy, realizing the all-round improvement of efficiency and accuracy.

Application of professional route planning

The remote controller with screen has built-in brand-new GS RTK App to help users intelligently control Phantom 4 RTK to collect data. GS RTK App provides various route planning modes, such as waypoint flight, ribbon flight, photogrammetry 2D, photogrammetry 3D, terrestrial flight, regional division and so on. It also supports KML/KMZ file import, which is suitable for different aerial survey application scenarios. ? The remote controller with screen integrates a 5.5-inch 1080p high-brightness display screen, which can still be clearly displayed in strong light environment.

Develop proprietary applications

The SDK remote controller can be directly connected to your Android or iOS mobile device to run applications such as DJI Pilot and GS Pro Ground Station Professional Edition. Users can also develop third-party applications through DJI mobile SDK according to business characteristics, and create customized solutions to closely integrate Phantom 4 RTK with operational scenarios.

OcuSync image transmission system

OcuSync image transmission system is stable and reliable, providing 7 kilometers of high-definition image transmission, and easily coping with large-scale surveying and mapping tasks.

*FCC standard, measured in undisturbed outdoor open environment. The longest flight distance depends on the strength and stability of the image transmission signal. Unless you get permission, you must fly within sight.

Seamless compatible D-RTK 2 high-precision GNSS mobile station

It can be used with D-RTK 2 high-precision GNSS mobile station to obtain real-time differential data. Hand-held D-RTK 2 mobile station can also measure points and collect precise coordinates of target points.
