【Zhengdian Atom i.MX93 Development Board】2.1 Face Recognition Attendance Machine Environment Construction--opencv and opencv-contrib [Copy link]

Preface:

The face recognition part mainly uses opencv, and no other third-party libraries are used. This chapter mainly records the compilation process of opencv and opencv-conturb. Host environment: ubuntu20.04 opencv version: 4.8.0 opencv-conturb version: 4.8.0 (remember that the versions of opencv and opencv-conturb must be consistent).

1. Download cmake-gui

Just two steps

sudo apt-get install cmake
sudo apt-get install cmake-qt-gui

2. Download opencv and opencv-conturb source code

You can download it directly from GitHub, but the download speed is worrying. You can sync it to your own gitee repository, and the download will be much faster.

//下载opencv-conturb-4.8.0
git clone https://gitee.com/cool-ditch-repair/opencv_contrib1.git
//下载opencv-4.8.0
git clone https://gitee.com/cool-ditch-repair/opencv.git

3. Compile and install

cmake -DENABLE_PRECOMPILED_HEADERS=OFF -D CMAKE_BUILD_TYPE=Release -DBUILD_TIFF=ON -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=/home/airobot/opencv-4.8.0/opencv_contrib-4.8.0/modules/ ..

make -j16
make install

4. Cross-compilation

1. In any directory, enter the cmake-gui interface:

$ sudo cmake-gui

2. Configure build target options

3. Configure the compiler

4. Specify the compiled content, path, etc.

5. Execute configuration and generate Makefile

6. Execute the compilation and wait for errors:

Question collection:

================================

7. Compile and install the extension library opencv_contrib

Find the OPENCV_EXTRA_MODULES_PATH item and select the modules directory under the opencv_contrib-4.8.0 directory of the extension library source code

Click Configure to generate the configuration (if there is still red, click it several times until the red disappears)

Click Generate to generate Makefile

8. Compile and install

Record:

Since the entire compilation process is actually carried out on the company's computer, there are currently no detailed process screenshots on the computer. All process pictures will be added tomorrow.

This can be replayed... I'll give it a try! Thanks for sharing!

Automatically mount gpu of imx?

imx.93 doesn't seem to have a GPU, and the screen display is not very smooth

Yes, I remember it had a 2D or 3D GPU. A high-end product like imx9 should not be without a GPU.

Really not, I went to look for it again

Because when I ran the factory image, I felt something was wrong, it wasn't smooth, and then I saw that it didn't have a GPU

This film should be the highest in the imx series, right? No?

But it seems that 93 has 2D

I checked it out again, and it's indeed 2D.
