AD-96TOF1-EBZ

Introduction

The AD-96TOF1-EBZ is a proven hardware platform for depth perception. When paired with a processor board from the 96Boards ecosystem or Raspberry Pi family, it can be used for 3D software and algorithm development. This modular platform can be used as a baseline to design a ToF system and will allow customers to start developing their software and algorithms while the hardware can be modified for their specific application. The solution has VGA resolution which means that objects can be detected to a higher level of granularity than other 3D ToF solutions, an ability to detect depth in strong ambient light conditions and multiple range detection modes for increased accuracy. A native and host SDK is provided. The SDK also provides OpenCV, Python®, MATLAB®, Open3D and RoS wrappers so that developers can use them to simplify application development.

The full system hardware includes:

  • Laser Transmitter Board
  • AFE Receiver Board

High level specification

Rev C board

  • Range
    • Near: 25cm to 80cm
    • Medium: 30cm to 4.5m (Rev.B: 80cm to 3m)
    • Far: 3m to 6m
    • Accuracy: < 2% for all ranges
  • Frame Rate upto 30fps dependent on processor board, OS and interface to host computer
  • Resolution 640 x 480 pixels
  • Operating Temperature -20⁰C to 85⁰C
  • 940nm VCSEL with 110⁰ x 85⁰ batwing profile diffuser
  • Receive lens: FoV 90⁰ x 69.2⁰ including 940nm BPF
  • 96Board mezzanine high speed and low speed expansion connector compatibility
  • Raspberry Pi camera connector to connect to any compatible processor board
  • Connectivity support for USB or Network(WiFi, Ethernet)
  • 5V DC Input
  • 20W max power consumption

Laser Board

  • The laser board has 4 individual lasers with appropriate precision driver and power components for accurate firing of the lasers.
  • The board is designed with the lasers positioned so that they fit around the AFE board CCD sensor when mated together. This position gives optimum performance for a wide range of use cases minimizing any effects of shadowing.
  • It receives power and all control I/O through the interface connector.

AFE Board

  • The AFE board contains a Panasonic CCD Sensor combined with ADDI9036 TOF Signal Processor with necessary power and timing signal chains.
  • Optics are fitted to the board using industry standard mounting adapters to give a wide field of view, but can be changed based on individual use cases. There is a threaded adapter for mechanical mounting on an optional tripod stand.

Application Development

SDK Architecture

The system has options of USB, Ethernet or Wi-Fi to connect to a host computer, this flexibility enables evaluation across a wide range of use cases and environments. Sampling rates of up to 30fps are supported. Data is fed from the depth camera to the processor board over MIPI-CSI interface. This data is read using V4L2 capture driver and in-turn either feeds it to native SDK or sends it to the Host SDK over Ethernet, WiFi and USB interfaces. Native/Host SDK provides this data to user applications for further use. For ease of application, the SDK also provides OpenCV, Python and MATLAB wrappers such that developers can simply use these wrappers to develop application.

The Depth Perception Rapid Prototyping Platform supports a wide range of operating systems and programming languages. An open-source SDK that accompanies the hardware platform enables you to extract depth data from the camera on the processor and operating system of your choice. Windows and Linux support are built into the SDK as well as sample code and wrappers for various languages including Python, C/C++ and MATLAB. The SDK also integrates with 3rd party technologies like OpenCV and RoS.
