Where can I find an object detection example in C/C++ for the Jetson Nano? I did one of the online courses on deep learning, but the examples were done in python. Any similar courses available in C/C++?

Hi xplanescientist, see the object detection portion of Hello AI World: [url] https://github.com/dusty-nv/jetson-inference/blob/master/README.md#hello-ai-world[/url]

I followed the object detection portion of the Hello AI World. The examples work, both the image-recognition and live camera-recognition. It runs very fast, and the big heat sink really gets hot. Eventually I’d like to couple the live camera program with another robotics project. So is it possib…

See this section of the tutorial for creating your own simple CMakeLists.txt for building an external project: [url] jetson-inference/imagenet-example-2.md at master · dusty-nv/jetson-inference · GitHub Note that I removed the dependency on Qt4, but forgot to update this part of the tutorial for th…

Hello, the “my-recognition.cpp” example worked. Straightforward and streamlined with good explanations. However big trouble with the live camera recognition program (“imagenet-camera.cpp” in link below). No luck after many hours of troubleshooting. https://github.com/dusty-nv/jetson-inference/bl…

Can you post the contents of my-camera.cpp and the results of make VERBOSE=1 ? It is not finding the definition of detectNet class. Is there an #include “detectNet.h” or #include <jetson-inference/detectNet.h>? The new CMakeLists also does not have these: find_package(jetson-utils) find_package(…

So I put in your suggestions, and it seems to compile. The relative paths are required in the #include statements, otherwise it does not work. I executed the program, and although it takes several minutes to show the live camera feed, it appears to run. But it does not identify the object. Here …

Okay, all works just fine, I was mixing up inference methods. I successfully compiled and ran an (1) Image Recognition example and (2) Object Detection. Image Recognition working example: /* * Copyright (c) 2017, NVIDIA CORPORATION. All rights reserved. * * Permission is hereby granted, free o…

Also tried the Semantic Segmentation live camera feed C++ example from link below. Used similar CMakeLists.txt file from previous thread. Segmentation runs, but execution is very slow - only 2 fps. I fed the camera 4K video from youtube and it detected nothing, even if I paused the video. [url] h…

I have been working on new segmentation models based on FCN-Resnet18 with improved performance - they currently live in the ‘pytorch’ branch. See here for updated documentation: [url] https://github.com/dusty-nv/jetson-inference/blob/pytorch/docs/segnet-console-2.md[/url] I am updating the documen…

Thank you very much. I am following your changes in the Pytorch branch with great interest. I would like to install the nano with semantic segmentation on a multicopter. Best regards, Wilhelm

Can you try launching with --threshold=0.2 or trying facenet or ssd-mobilenet-v2 to confirm that the program is working? Does detectnet-camera with this model work for you while your program does not?
