SIYI ZT30 Introduction

Product Features

Hybrid Four Sensors

A hybrid-sensor solution was born to lead the industry. Zoom cameras, thermal imaging cameras, laser rangefinders, and wide-angle cameras collaborate efficiently to detect heat sources while measuring distance to targets, capturing clearer pictures, and having a broad view.

High-Resolution Thermal ImagingFull-Screen/Point-Anywhere Temperature Measuring

SIYI ZT30 four-sensor optical pod carries a 640 x 512 resolution thermal imaging sensor of 19 mm focal length and 30 fps frame rate. Vision is wide and far. The video is smooth and clear. Quick and accurate reactions can be taken as long as an abnormal heat source is detected where temperature can be measured by touching on infrared images.

High-Accuracy Laser Rangefinder

ZT30 optical pod comes with a 1200-meter range and 0.1-m measuring accuracy rangefinder. Sensitive and reliable, can obtain accurate coordinates in real time in high-risk operation scenarios, helps command decision-making, and ensures safe operation space.

AI Enhanced Smart Identify and Tracking

Built-in NPU neural network computing unit, combined with SIYI Technology’s self-developed new AI algorithm, ZT30 optical pod will be able to automatically identify people, vehicles, ships, and other moving targets. Through the cooperation of the gimbal attitude control and flight control system, it can realize autonomous identification, positioning, and even continuous tracking. With the automatic zoom function of the visible light camera, the target will always be in the center of the screen and maintain a clear and visible screen ratio.

*The AI feature is under development and can be supported by an upgrade later.

Professional Comprehensive UAV Imaging System

In addition to the 180x hybrid zoom (30x optical zoom) 1/2.7-inch Sony 4K image sensor camera, ZT30 also has a wide-angle camera with 2K resolution, providing an unprecedented wide view and panoramic shooting capabilities. The scenery is clear, the algorithm is fast and accurate, and the viewpoint is automatically focused, making it easy to produce grand pictures. Silky movement, smooth zoom, distant scenery, now within reach.

*The images recorded by ZT30 will have GPS location information and time attributes.

Infrared Zoom

The thermal camera supports 2x digital zoom and accurately controls more picture details.

Video Split-Screen

ZT30 can split screen for video streams from any two sensors freely and the third sensor can be streamed in the floating window simultaneously.

Starlight Night Vision

The ultra-sensitive starlight CMOS keep images bright in low-light environment.

Point To Focus

Point anywhere to focus the lens from the zoom camera to get a clear view of the selected part of the screen.

Focus Tracking

Zoom camera stays focused and keeps filming smooth videos while users are scaling images.

HDR

HDR (High Dynamic Range) precisely captures good details of highlights and shadows in dynamic scenes to get true colors and natural brightness.

Limitless Yaw Axis Rotation Upgraded Quick Release and Anti-Vibration

The yaw axis of the ZT30 gimbal rotates limitlessly. Hanging below VTOL drones or planes, the ZT30 optical pod captures 360 degrees around. SIYI’s quick-release structure is upgraded with even better stabilization and more load-bearing. It is compatible with ZR30 and will support more SIYI payloads in the future. Welcome to follow-up.

Incomparable Gimbal Control Interface

SIYI optical pods provide powerful compatibility to contribute to smart robotics ecology in all dimensions. They can be controlled through traditional S.Bus signal by switches and dials, or through Ethernet by touchscreen or by UDP based on SIYI SDK, or through UART by SIYI SDK or popular open-source protocols like Ardupilot driver and Mavlink.

*Developing SIYI SDK through Ethernet UDP or UART can control SIYI optical pods by protocol and acquire relevant data.

*The Mavlink protocol control for SIYI optical pods is in development and will be supported by an upgrade later.

Gimbal Motion Mode/Upside Down Mode

The gimbal automatically activates upside down mode when it is placed upside down, very convenient to mount on multiple kinds of vehicles like UGV, USV, robot dogs, and more robotics.

Follow Mode

Horizontally, the gimbal follows when the aircraft rotates.

Lock Mode

Horizontally, the gimbal does not follow when the aircraft rotates.

FPV Mode

The gimbal rotates simultaneously as the aircraft rolls to get an FPV view, and output enhanced stable images.

High Accuracy and High Collaboration Control Algorithms

During the development stage of ZT30, SIYI has made multiple breakthroughs in control algorithms and stabilization algorithms.

IMU Calibration Algorithms

Compensate and correct errors of the inertial measurement unit, reduce interference factors such as zero bias, scale factor, inter-axis error, temperature drift, noise, etc., greatly improve the measurement accuracy of IMU, and improve the stability of the gimbal in large temperature differences, wide margin steering, and strong vibration environments.

Attitude Fusion Algorithms

Comprehensively utilize the data of sensors such as accelerometers and gyroscopes, obtain the pitch angle, roll angle, and yaw angle of the gimbal through mathematical models and filtering algorithms, and fuse this information to effectively improve system performance, stability, and robustness.

Industry-Level 3-Axis Stabilization Algorithms

Deeply integrate and utilize 3-axis gyroscopes, 3-axis accelerometers, PID controllers, motors, and magnetic encoders to achieve gimbal attitude stabilization control and continuously output stable high-definition video images during motion.

High-precision FOC Motor Control Algorithms

Control the current components of the motor to control torque and magnetic field respectively, thereby achieving decoupling control of the brushless motor and greatly reducing picture jitter.

Advanced Guide for SIYI Gimbal SDK Integration

This special guide is to help developers (especially whose development is based on Linux platform) use SIYI gimbal SDK.

Mark

Before using the guide, please do read the chapter 3.3.1 to 3.3.5 of the user manual.

This guide is using UDP protocol:

Go to chapter 3.3.4 of this manual for SIYI Gimbal Camera SDK Communication Code Examples and fill your required examples to “send_buff” following the below format in hexadecimal.

Chang the gimbal camera’s server port and IP addresses to what you need. The double quotation marks of the IP addresses should be kept.

Create a socket keyword.

Send data to the gimbal camera and do not revise.

Receive data responded by the gimbal camera and do not revise.

Print the received data in hexadecimal and do not revise.

Following the above steps, compile and run the SDK and you will see the printed data below, which means data can be sent and received normally. At this moment, please observe if the gimbal camera executes the relevant actions.

Mark

Before using the SDK to communicate with the gimbal camera in UDP protocol, please do make sure that

the device and the gimbal camera are in the same gateway, which means that ubuntu can ping the gimbal camera’s IP addresses successfully.

If they still didn’t communicate, the possible reason is that the Windows firewall is interrupting the sending and receiving of data, then try to disable Windows firewall temporarily.

The “Gimbal Config” menu also supports abundant and core features of SIYI gimbal camera, such as, checking camera firmware version, modifying camera IP addresses, selecting camera source for main / sub stream and video recording, switching camera resolution or zoom mode, enabling / disabling thermal camera’s synchronized zoom, enabling / disabling boot recording.

About Camera Configuration

IP Config: Modify camera IP addresses.
Gateway Config: Modify camera gateway.
Gimbal Working Mode: Switch gimbal working mode (follow mode, lock mode, FPV mode).
Main Stream: Select camera source and switch output resolution for the main stream.
Sub Stream: Select camera source and switch output resolution for the sub stream.
Record Resolution: Select camera source and switch video resolution for recording.
Zoom Mode: Switch zoom camera’s zoom mode (normal, absolute zoom).
Boot Record: Enable / disable automatic video recording by TF card as soon as gimbal camera is powered.

Gimbal Calibration

The “Gimbal Calibration” can help users do IMU calibration, IMU Constant temperature calibration, and accelerator hexahedral calibration.

IMU Calibration

IMU calibration can keep the inertial measuring unit’s accuracy and reliability.

Steps

Click “Check”, gimbal camera will power off automatically. Meanwhile, please follow the message box and place the gimbal camera on a flat surface and make sure that the IMU is static. Do not touch or vibrate the gimbal camera. Then go for “Start Checking”.

The PC assistant start to check IMU status automatically to determine if the gimbal should be calibrated.

If IMU is working normally, there will be a message box to indicate “not necessary to calibrate”.

If IMU is not working normally, there will be a message box to indicate “calibration is necessary”.

Click “Start Gimbal” and “Calibrate”.
The message box will say again “please follow the message box and place the gimbal camera on a flat surface and make sure that the IMU is static. Do not touch or vibrate the gimbal camera”.

IMU calibration menu will display “calibrating”.

After a few seconds, IMU calibration will be finished.

IMU Constant Temperature Calibration

Specially designed for using gimbals in scenarios with big difference in temperature to avoid the situation that gimbal behaves abnormally because IMU cannot reach constant temperature normally and fast when the environment temperature is far from IMU constant temperature.

Before calibration, please input the environment temperature of your operating field, the software will start to calculate the target IMU constant temperature so that IMU can reach the temperature fast after powering on gimbal camera. The software is showing IMU temperature in real-time.

Accelerator Hexahedral Calibration

Accelerator hexahedral calibration can calibrate the accelerator’s sensitivity, zero bias, and inter axis error, etc. During calibration, the gimbal should be placed in all hexahedrons to record accelerator’s output value on each orientation and build the error model. Hexahedral calibration can keep the accelerator’s accuracy and reliability.
