Introduction

This explanation assumes that the i-PRO camera application development environment has been completed.
If you are not ready to build the development environment, please refer to here to complete it.

Also, in this tutorial, the SDK installation directory is described as ${SDK_DIR}.

Operation overview

opencv_edge_detection_app is a sample app that detects and displays edges in an image.
This app display an image that emphasizes the outline, etc., as shown below.

Open

External libraries required for operation

To build with C/C++, need below:

OpenCV

Directory path of the sample app

The C/C++ source code is stored below.

${SDK_DIR}/src/adamapp/opencv_edge_detection_app

No Python source code.

How to build the sample app (C/C++)

See here for building with C/C++.

How to use the sample app

Here is an example of edge detection in an image captured by a camera.

-Before edge detection

Open

-After edge detection

How to change preferences

This application has some preferneces which a user is able to change.
When changing some preferneces, push "AppPrefs" button in "ADAM OPERATION UI" html page.

Resoultion:
Resolution to get jpeg images.
Specfify QVGA(320x240) or VGA(640x480) or HD(1280x720) or FHD(1920x1080).
However, by the ability of the camera, it may not work with the specified value.

Frame rate:
Frame rate to get YC(YUV) images which are encoded to jpeg images.
Specify 1 or more.
However, by the ability of the camera, it may not work with the specified value.
