Introduction
On this page you will see how to write your own image processing application for iam and stream the result over iAMGigEServer to a host system.
| Info |
|---|
The iam linux system contains build tools therefore it is possible to compile native on the camera. More Details can be found here Pre-Installed Open Source Libraries |
The application is shown in the diagram below.

Example Repositories
Small and simple example applications:
Example Name | Compiling | Discription | Repository |
|---|
...
sw_remap_synview | nativ/cross | The example remap_synview uses the function cv::remap from OpenCV. After processing the image is sent out via GigE Server. | |
|---|---|---|---|
sw_remap_boxfilter_synview | nativ/cross | The example sw_remap_boxfilter_synview uses the cv::remap and cv::boxfilter function from OpenCV. It demonstrates the execution of multiple sw- and hw-functions in different processing threads. The connection between the threads is established with two image-buffers. One is written, the other is read and vice versa. After processing the image is sent out via GigE Server. | |
sw_scaler_synview | nativ/cross | The main processing consists of a simple c-code scaler for horizontal and vertical rescaling. After processing the image is sent out via GigE Server. |

Edit Source Code
Adapt two functions of app.h class
GigeEventCallback:

Edit XML -
...
Define a new GenICam Feature
An example XML can be found here: /opencv_dice/src/master/smartDices/smartDices.xml
Add new feature to CustomControl cathegory, e.g. WhiteBalanceAuto:
Define new feature values:
Define new register address:
Implement processing inside
void appClass:: SmartFeatureCallback ( … )(aliasGigeEventCallback) callback. Code snippet can be found in the Info toolbox at bottom left of SynView Explorer.
