Using Ti am68 to implement toy car auto drive.
Using TI am68 to detect signs for auto driving.

I don't konw why I CAN NOT add toy traffic corn to TI_SK68 by web model composer. (2024/04)
I try web model composer and ok in 2024/06.

Work around, short term solution, using small bottle instead of toy traffic corn.
The native model, ONR-OD-8200-yolox-nano, is good at detecting bottle.
Thus, my plan,
(1)The am68a runs "wget/curl" to get jpg file from WiFi web camera on toy car.
(2)The am68a detect all bottles X1Y1X2Y2 in the jpg file.
(3)Then am68a controls toy car by USB-FT232 -> arduino -> PWM -> servo -> motor.

The command to stop Ti_SK68 out-of-box demo:
/etc/init.d/edgeai-launcher.sh stop

Ti_SK68/SDK9.1 comes with python demo about inference.
/opt/edgeai-dl-inferer/tests/test_python/app_dl_inferer_test.py
app_dl_inferer_test.py call app_dl_inferer_post_process.py to draw rectangle.
We can add some code in app_dl_inferer_post_process.py to output rectangle X1Y1X2Y2.

copy pic_test/bottles.jpg to am68 /tmp by scp/ssh.
run:
cd /opt/edgeai-dl-inferer/tests/test_python
python3 app_dl_inferer_test.py -d /opt/model_zoo/ONR-OD-8200-yolox-nano-lite-mmdet-coco-416x416/ -v 0.3 -i /tmp/bottles.jpg
Then, you get a jpg file of detection_output0_ONR-OD-8200-yolox-nano-lite-mmdet-coco-416x416.jpg at
/opt/edgeai-dl-inferer/tests/test_python

Made by model composer.(2024/06)

Copy ad25e250/ to /opt/model_zoo/
Reboot system
The [Custom] Model add item of ad25e250. Run it with Camera / USB Camera 0

copy pic_test/cones.jpg to am68 /tmp by scp/ssh.
run:
cd /opt/edgeai-dl-inferer/tests/test_python
python3 app_dl_inferer_test.py -d /opt/model_zoo/ad25e250/ -v 0.3 -i /tmp/cones.jpg
Then, you get a jpg file of detection_output0_ad25e250.jpg at
/opt/edgeai-dl-inferer/tests/test_python
