I installed Jetpack 3.0, and buildOpenCV.sh , but encouter the Makefile:160: recipe for target 'all' failed error. I don't if I lost some configuration or something else?

After I build opencv the files are all there, but there is no opencv.pc file so I can't use pkg-config to find the libraries. I tried building it using the buildOpenCV.sh and installing the package created in buildAndPackageOpenCV.sh, but in both there is no opencv.pc file. I've look everywhere on my jetson, but the file isn't there.

Should this be working with JetPack 3.2 (i.e. L4T 28.2 RC)? When I try, it builds OpenCV without CUDA support...

opencv‘s dnn moudle is now support for Nvidia cuda, and needs opencv version of 4.2.0. Can you updata the opencv version and build opencv with DNN_CUDA support? Please~

I set -DBUILD_opencv_python3=OFF \ to ON and then installed but I cannot import cv2 in a python3 environment.

I run opencv on my TX2.
Here is the error:

Does it mean that my TX2 without enough memory to run my program?

How can I fix it?

Thank you !!!

Hi, previously I had problem realizing realtime SSD detection with V4L2 format error which seems to be an opencv error. So I decided to reinstall opencv following the instruction. However, I got the following error at 75% completion:

Previously I installed opencv3.4.0 myself following other tutorial. And it seems in my home directory, there were opencvtegra folders installed before (there was another collegue working on this Jetson TX2 before). I unistalled opencv by "sudo apt-get purge libopencv*" and removed opencvtegra foler. Any idea what might be the problem?

Thanks in advance!

When I use opencv with GStreamer, it will always error.

Hi,
I installing opencv 3.3.0 on my raspberry pi 3, using the cmake with the following configure:
cmake -D CMAKE_BUILD_TYPE=RELEASE
-D INSTALL_C_EXAMPLES=OFF
-D INSTALL_PYTHON_EXAMPLES=ON
-D CMAKE_INSTALL_PREFIX=/usr/local

This library has worked great for single videocapture but when I try to do 2 at the same time eventually my jetson freezes and stops responding to mouse and keyboard inputs. I posted an example usage of videocapture.
cv::VideoCapture cap1(pipeline1, cv::CAP_GSTREAMER);

Hello,

Can the script also be used with TX1 ?

Thanks,

Hi all,
I install OpenCV package as the following step:

./buildOpenCV.sh
make
sudo make install

However,I got these error

I have checked the packge is installed in the directory /usr/local/lib
Can anyone help me?
Thanks in advance!!

Firstly ,thanks for your work
I have some question
when I complete the script , is it necessary to configure the environment variables for opencv ？
Is there any way to tell if cuda is accelerating opencv ?
Thanks again

This my issue https://stackoverflow.com/questions/58386655/openni-launch-is-neither-a-launch-file-in-package-openni-launch-nor-is-openni

I m using the following to detect objects using SSD mobilenet (CAffe) on Jetson TX2 with opencv3.4.1 and Cuda 9.0

blob = cv2.dnn.blobFromImage(cv2.resize(frame, (300, 300)), 0.007843, (300, 300), 127.5)
net.setInput(blob)
detections = net.forward()

The tegrastats show no GPU usage at all. All the cores of the CPU are utilized properly, however GPU utilisation is zero.

How can I enable GPU usage on the Jetson for faster FPS on videos ?

Thanks

In case I'm trying to install OpenCV version 3.4.2 or 3.4.4 for example the Python checking which performed as the last step of the installation process is failed due to unresolved symbol "...dnn..." despite the fact that the cv2.so file was generated and the import cv2 command identify it.

Please advise.

Hi ,

How can I use the script to build OCV for TX2 via PY3?

Thanks for help in advance!

Hello,
Any idea ??
Thanks,
Vincent

First of all: Thanks for having all this stuff open-source:+1:

I have a TX2 with the latest JetPack 3.1 (L4T 28.1) and have uninstalled the preinstalled OpenCV version (sudo apt-get purge libopencv4tegra*). After that I installed OpenCV again using your script. That all worked!
The gstreamer_view.cpp works as well.

But if I run python cannyDetection.py I get

camera open failed

Any ideas?

Hi,

It would be great if you are able to update the repository for Jetpack 3.2.
Is it also possible to provide a simple example showing cuda working with OpenCV?

Thanks for your great support!
Cheers,
Burak

Hey everyone,

i got an Issue while building the OpenCV based on your description. This could be an issue with the new Jetpack 3.2 and Cuda 9.0 because some OpenGL support in Cuda is broke.

If someone has the same problem, try the following which helped me:

Edit the file: "/usr/local/cuda-8.0/include/cuda_gl_interop.h"

Find the code:
#else /* __APPLE__ */

It should be around line 7.. then replace all the If Def's with the following to force include of GL/gl.h

#else /* __APPLE__ */
 
 #include <GL/gl.h>
 
 #endif /* __APPLE__ */

make -j6 and get error.

Hi,
Can we not build opencv with opencl support (ON) on the Jetson TX2 ??

I am unable to use opencvdnn on gpu .. hence wanted to use the opencl for gpu usage.

Any help would be great

Thanks

hi
i have manifod g2 (DJI pc) with:
jetson tx2
jetpack 3.2
cuda 9-0

i try to use dnn with cuda.
i try to compile opencv 4.5.1 with opencv_contrib:

How to install opencv-contrib on jetson tx2

Hello,

i did you installation tutorial as you said. But it seems like, my python doesnt know which OpenCV version to use.
When i try your Example, i get an error and the hint, that python is accessing openCV version 3.3.1
The error looks like this
Called with args: Namespace(video_device=0) OpenCV version: 3.3.1-dev ('Device Number:', 0) camera open failed
I think python doesnt know that i build openCV from source. I double checked in the terminal an i get these issues:

`nvidia@tegra-ubuntu:~/OpenCVTX2/Examples$ python3
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.

import cv
Traceback (most recent call last):
File "", line 1, in
ImportError: No module named 'cv'
import cv2
Traceback (most recent call last):
File "", line 1, in
ImportError: /opt/ros/kinetic/lib/python2.7/dist-packages/cv2.so: undefined symbol: PyCObject_Type
`
What have i done wrong in the build process?
