Addressing the Challenges of Creating Infra-Red Vision Systems for the IIOT and IOT
Embedded vision is ubiquitous, being used across a range of applications such as ADAS, vision guided robotics, and of course the IoT and Industrial IoT. Increasingly, along with the visible spectrum, embedded vision systems rely upon the wider electromagnetic spectrum such as the infra-red spectrum. This spectrum is used in IIoT applications for the monitoring of temperatures on key equipment providing prognostics, or within IoT applications where it enables users to see in low light conditions or provide the ability to measure the temperature of a sleeping baby remotely. This presentation will outline the different formats of IR imager, cooled and uncooled, and the benefits and challenges which come with each type, before looking at the different use cases for each sensor type and outlining the challenges these present for the embedded vision designer. For example, non-uniformity correction, spatial and temporal noise, and methods for addressing them. Moving on, the presentation will focus upon the constituent elements needed to create an IR image processing system using a heterogeneous System on Chip (SoC). The detailed example presented will be focused on a solution based upon the MiniZed (Zynq device) combined with the FLIR Lepton. This range of image sensors provides both uncalibrated for simple IR imaging, and calibrated IR devices which accurately gauge the scene temperature for use in thermographic applications, while being cost aligned for the IIoT and IoT applications. In this case, the FLIR Lepton uses standard SPI and I2C for interfacing, but we have a range of potential display options, for instance a local display (touch display for control panel), WIFI or Bluetooth for wireless connectivity. The session will introduce the architectural solution, segmentation between processor cores and programmable logic, along with the functional blocks required within the programmable logic. With the hardware design explained, the software stack will be outlined ensuring attendees understand the complete architecture of the solution. Of course, for an IIoT application, this solution provides the any-to-any interfacing required to interface with actuators and drives, along with providing the processing capability, to make independent processing decisions at the edge based upon the information contained within the scene. As the presentation will be talking about IoT and IIoT, which are typically remotely deployed, the session will also lightly touch upon the requirements for safety, power efficiency, application and transmission security and anti-tamper, along with how these can be embedded into the design.
