Product Features

Powerful Imaging System

A8 mini carries an 1/1.7-inch Sony image sensor, an 8 megapixels CMOS with remarkable photosensitivity ability, impressive 4K video recording and photography.

Up to 6x digital zoom. The scenery is clear, making it easy to produce grand pictures.

*The images recorded by A8 mini will have GPS location information and time attributes.

Starlight Night Vision

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

HDR

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

AI Enhanced Smart Identify and Tracking

Built-in NPU neural network computing unit, combined with SIYI Technology’s self- developed new AI algorithm, A8 mini gimbal camera will be able to automatically identify people, vehicles, ships, and other moving targets. And 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.

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

 

Incomparable Gimbal Control Interface

SIYI gimbal cameras 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 on 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 upgrade later.

Gimbal Motion Mode Upside Down Mode

Gimbal automatically activates upside down mode when it is placed upside down, very convenient to be mounted on multiple kinds of vehicles like UGV, USV, robot dog, and more robotics.

Follow Mode

Horizontally, gimbal follows when aircraft rotates.

Lock Mode

Horizontally, gimbal does not follow when aircraft rotates.

FPV Mode

Gimbal rotates simultaneously as aircraft rolls to get FPV view, and output enhanced stable images.

High Accuracy and High Collaboration Control Algorithms

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.

Various Video Output, Ultra Low Latency

A8 mini gimbal camera provides triple popular video output options, Ethernet, HDMI, and CVBS (AV). RC plane and FPV drone users can experience very low latency FPV through CVBS video output and analog image transmission system.

*A8 mini configured as ultra-low-latency mode, CVBS output to analog FPV transmitter, view from the monitor connected to FPV receiver, the overall latency is 60ms. Direct HDMI output from A8 mini to monitor, the latency is 65ms.

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:

  1. 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.

2. 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.

3. Create a socket keyword.

4. Send data to the gimbal camera and do not revise.

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

6. Print the received data in hexadecimal and do not revise.

7. 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.

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
  1. 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”.

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

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

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

5. Click “Start Gimbal” and “Calibrate”.

6. 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”.

7. IMU calibration menu will display “calibrating”.

7. 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.
