Hi We developed in last years a stereoscopic people counter application with Apalis TK1.
We have an own embedded carrier board Apalis compatible and a usb stereocamera.
Our application made a stereo map with libSGM cuda and implement a blob opencv tracking with 15fps average.
Unfortunately TK1 is at the end of life and we are working in desktop environement with opencl instead of cuda.
We of course don’t know if performance will be the same or worse; imx8 are not here yet to try on target, but in that way the question is:
“doas it exist a setup which can maximize performance in opencl, in special mode to stereo opencl matching?”
for example with TK1 we used this boot setup:
#!/bin/bash
SD_BASE_PATH=“/data/”
BASE_PATH=$(dirname $(readlink -f $0))
USB_BASE_PATH=“/mnt/usb”
export BASE_PATH
echo 234 > /sys/class/gpio/export
echo 237 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio237/direction
echo 1 > /sys/class/gpio/gpio237/value
echo “7” > /sys/class/backlight/backlight.3/brightness
export LD_LIBRARY_PATH=/data/lib
export LD_LIBRARY_PATH=/usr/local/cuda/lib:/data/lib
#/bin/bash
echo “Disabling USB autosuspend…”
echo -1 > /sys/module/usbcore/parameters/autosuspend

python -c ‘import ctypes; ctypes.cdll.LoadLibrary(“/usr/local/cuda-6.5/lib/libcudart.so”).cudaDeviceReset()’

echo “ip addr flush dev eth0”

Any kind of suggestions?
thanks…
