Image vision

DAB-Embedded BV has experience with the integration of next image sensors:
  • Linear CMOS
  • CCD sensors (Hamamatsu, Sony)
  • Event-based sensors EVS (Sony)
  • TDI sensors (Gpixel, Hamamatsu)
  • Monochrome and Color (Bayer) sensors with YUV, COMP8, and RAW8/RAW10/RAW12/RAW14 output formats (plan and compressed)
    (Gpixel, Sony, Omnivision, Onsemi)
  • 3D Time of Flight sensors (Sony, ADI, Teledyne)
With such interfaces:
  • SLVS-EC (FPGA IP core)
  • MIPI CSI-2 C- or DPHY
  • LVDS
  • Parallel interfaces (DVP)
DAB-Embedded in collaboration with partners we are able to supply MIPI/DVP/SLVS-EC camera modules for various applications.

Modules can be in mobile and industrial formats. Mobile camera modules can be equipped with an AutoFocus system (with VCM chip) and 5-6 small lenses to achieve the best quality or fixed focus lens system. Customers can select a field of view (FoV) angle normally from 33 deg to 180deg with a pinhole or fisheye lens (depends on module construction – if you need specific parameters – ask us, and we will help to calculate).

For example, DAB-Embedded has Belgium stock of the next sensor modules:
·         Sony IMX298 (16Mpix) - read more here
·         Sony IMX219 (8Mpix)
·         Sony 64Mpix - read more here
·         Omnivision OV8865 (8Mpix)
·         Omnivision OV13865 (13Mpix)
·         Onsemi AR1335 (13 Mpix) - read more here

We have experience with:
  • Autoexposure algorithms (HF and PDAF)
  • IQ tuning (on/off-chip lens shadow correction LSC, black level compensation BLC, bad pixel masking, Gamma correction, CCM, CFA configuration, AWB configuration, CLM)
  • RAW10/RAW12/RAW14 conversion to YUV/RGB using GPU OpenCL plugins and ARM SIMD/OpenMP plugins
  • Building Gstreamer pipeline with color conversion (on ISP), compression using hardware codecs, such as H.264, and H.265, and making a network streaming interface (RTSP).
  • Making a video overlay application on top of camera video streaming.
  • Adding Region of Interest (ROI) and scale modes to the drivers (possible to change online during streaming/offline – eg digital zoom).
  • Preparation of video/imaging data for post-processing using Machine Learning / Deep learning algorithms and computer vision algorithms.
    • We have ready the next pipelines using ML
  • Building full image processing pipeline including computer vision pipeline.
  • Using an accelerometer for image stabilization and compensation.
  • Using internal temperature sensors for image quality compensation. 
  • Building DSP, OpenCL, and SIMD processing modules (you can read them here).
  • Adding AI to customers’ video applications, and training models and optimizing it for the hardware platform.

We have our own developed solutions based on FPGAs:
  • Frame grabber: Intel Cyclone 10 GX FPGA (video ISP, DMA, PCIe core) + eFinix FPGA (MIPI CSI-2 RX 4-lanes 1.5Gbps each)
  • High-speed frame grabber: Xilinx Artix Ultrascale+ PCIe and MIPI CSI-2 RX 4 lanes 2.5Gbps each
Additionally, we have experience with transmitting video up to 4K2K video stream with 15 meters distance over coax cable together with power transmission (up to 36 VDC) using technology GMSL.
