Seems like a cool forum... I think this is the best place to ask this questions.
We design Thermal Imaging cameras which need quit a allot of custom image processing and custom sensor controls. What should we use FPGA or Micro controller?
Camera and video/image processing Brief
We have a 1024 by 768 12 bit per pixel(BW) image 30fp , coming in through a serial link.
The image then needs allot of image processing such as :3 point Calibration Custom Contrast enhance and detail enhancement Scaling Colourization AGC Blending Object detection
FPGA Approach: Completely possible no problem with custom device interfaces and horsepower.... However its an expensive approach. Has longer development time and seems to more difficult.
I am very interested in be able to use on of the TI MC such as Omap4.
This seems very appealing because of its onchip interfaces:
Memory Controllers Serial /Usb controllers Wifi/3g capabilities The device is composed of the following subsystems: ? Cortex?-A9 microprocessor unit (MPU) subsystem, including two ARM® Cortex-A9 cores
? Digital signal processor (DSP) subsystem ? Image and video accelerator high-definition (IVA-HD) subsystem ? Cortex?-M3 MPU subsystem, including two ARM Cortex-M3 microprocessors
? Display subsystem ? Audio back-end (ABE) subsystem ? Imaging subsystem (ISS), consisting of image signal processor (ISP) and still image coprocessor
(SIMCOP) block ? 2D/3D graphic accelerator (SGX) subsystem ? Emulation (EMU) subsystem
However as I have not worked much with these kind of multimedia application processor. I have not understood whether this kind of processor can be used for my application.
Can I implement my custom image processing blocks using the on chip DSP Cortex?-A9 microprocessor unit (MPU) subsystem ,Image and Video Acceleration and ISS blocks.
Is it possible to implement such processing algorithms:3 point Calibration Custom Contrast enhance and detail enhancement Scaling Colourization AGC Blending Object detection
and then Output it on an LCD.
Look forward to hear from you all soon.
