Delete files no longer needed
The information needed for debugging library is included in the OpenCV library you created.
We recommend that you delete this file to reduce the folder size as you do not need this to run the application.

Build the sample application
Build the sample application "opencv_edge_detection_app" and install it on the camera (eg, it can be installed from the green frame in the image below).
See here for how to buildPlease perform the build method according to each SDK version.
Open the app screen (red frame button in the image below),

Build the sample application
Before building the sample app, format the SD card using the screen below. (Please confirm in advance whether the SD card can be formatted. All data on the SD card will be erased.)
Once formatting is complete, the SD card as ext (ext4) and press the Set button.

The compiled module is created in “${SDK_DIR}/external/build/sample/docker/docker_volume/jpeg-9e”.
Deployment in AdamApp
Deploy the modules to use them with AdamApp.
Here we take “${SDK_DIR}/src/adamapp/jpeg_app” as an example.
Deployment in AdamApp
libjpeg module is installed in the following directory.
${SDK_DIR}/external/build/sample/docker/docker_volume/jpeg-
...
9e/.
...
Deployment in AdamApp
Deploy the modules to use them with AdamApp.
...
libs
libjpeg.so.9.5.0
Copy the above file to the AdamApp source directory.
${SDK_DIR}/src/adamapp/jpeg_

Deployment in AdamApp
libjpeg module is installed in the following directory.

Copy the above file to the AdamApp source directory.
${SDK_DIR}/src/adamapp/jpeg_app/external/lib/aarch64-linux-gnu |
Once copied, create a symbolic link.
| Code Block |

Build the sample application "jpeg_app" and install it on the camera (eg, it can be installed from the green frame in the image below).
See here for how to buildPlease perform the build method according to each SDK version.
Open the app screen (red frame button in the image below), and if the image of the captured by the camera is displayed, it is successful.
