The directory /saples/thermal-raw will start to fill up with thes types of files:
1. The decoded RGB frame of the video stream
2. The thermal raw data stored as binary binary output as it is received from the camera (if thermal raw export is activated)
3. Thermal data converted to numeric values. The data is stored as integer values in a csv file.
4. Thermal data converted to degrees Celsius. The data is stored as float values in a csv file. (only for TR sensors)
The single .csv files can then be viewed in any table calculation software:
Thermal values for each pixel of the sensor are listed in this table.
Update on .raw file processing:
The data exported by the SDK is decoded raw data. Image decoder supports two output formats: YUV420 and RGB (bgra). Which one is used needs to be specified while stsarting up the SDK. The sample program “thermal-raw” by default specifies this to be RGB:
Please see main.cpp:
```
/*
* Create a new eventstream client SDK object
*/
MxPEG_SDK::shared_ptr_t client = MxPEG_SDK_Factory::create(sinkAudio, sinkVideo, MxPEG_ImageMode::im_RGB, authHandler,notificationListener);
```
The RGB image output is plain image data that does not include further metadata like resolution or pixel format. Such formats are usually internally used by image processing tools, but rarely stored in files. To open such a file you’ll need to manually provide the necessary metadata (resolution, pixel format, …) Because of this, not many image viewers support loading such files.
The RGB output created by the SDK is stored using ARGB8888 pixel format. (See [https://en.wikipedia.org/wiki/RGBA\_color\_model](https://en.wikipedia.org/wiki/RGBA_color_model)). A simple image viewer that supports such plain formats is vooya (You can download the Linux version for free here: [https://www.offminor.de/downloads.html](https://www.offminor.de/downloads.html)). There is also an online viewer for such files at [rawpixels.net](http://rawpixels.net) (use RGB32, BGRA).
The .raw files contain the raw data as it is generated by the thermal sensor. I am not aware of any picture viewer that could simply visualize this data.
The data structure itself is described in the header file MxPEG\_ThermalRawData.hpp of the SDK. For each pixel the sensor generates a 14 bit value numeric value that represents a temperature. How to interpret this numeric value depends on the operation mode of the sensor. To covert this numeric value to a temperature you’ll also need a sensor (model) specific formula.
A far simpler way to access the sensor data is to use the convertTo() function of the SDK. This already knows all the relevant operational parameters of the sensor and can convert the raw value of a pixel coordinate to Celsius or Fahrenheit.

Hello,
here are some example files the thermal-raw stream creates:

Hello,
could I use Visual Studio Code for Windows?
Do you have any experiences with newer versions of Visual Basic 2015?

Hello Mx-MarieK,
as far as the documentation states it is possible to use VB2015.
In fact this is the system requirement to do this on Windows bases machines.
During the production of this article i was not able to purchase or check with VB,
so i could
only test the MAC and Linux based solutions.

HI!
I have a small question. I’m doing a development to use the sdk in an ARM device. But I have found the problem that the SDK is not compiled for this architecture and when trying to generate my development it cannot be compiled by eventstreamclient.a. There is another way to access the raw data or some way to have the SDK ready for ARM.

Hello jesusVidaip,
unfortunately, there is no way to compile and distribute a generic ARM version of the SDK.
This always needs to be specific for the OS running on the ARM device, as some other details we need to consider when compiling for the specified target system.
Please contact MOBOTIX Support with this request.

Hello,
I successfully managed to compile and run all the provided examples of the SDK. May I ask now what I have to change in order to obtain only one set of data. To be more specific:
In the main.cpp file I see the following lines:
/\*
\* The SDK library is single threaded, the function loop() acts as the main loop of the library. Call it repeatedly
\* from the applications main loop.
\*/
while(true) {
client-\>loop();
}
As far as I can see this is an infinite loop which produces the relevant data files: stream\_000001., stream\_000002., etc.
If I change the **while** loop with a **for** loop I manage to get a finite number of files but this number is different each time I run the script.
For example I added a **for** loop with 250 loops and on my first test I got 12 data files (from stream\_000001.\* to stream\_0000012.\*). On my second test I got 15 data files.
Why is this happening?

Hello Ioannis,
the “while(true) …” is essential for the scripts function and needs to run at all times.
If you wish to limit the number of received images, you need implement this in the VideoSink
where the individual images arrive.

Thank you for your response!
Could you guide me which lines of code do I have to change in the VideoSink file in order to obtain just one set of data? I want to avoid the infinite loop.
Thanks in advance

Hello Mx-DirkG!
I am working on integration Mobotix device to our system. I use EventStream SDK and I suffer from several bugs in it. I would like to fix these bugs. Is source code of EventStream SDK available for download?

Hello Dmitry,
unfortunately we can’t publish the source code due to some parts of it beeing patended code for MxPeg.
Our Support ([support@mobotix.com](mailto:support@mobotix.com)) will be happy to help you with finding a solution to your issues.
regards,
Dirk
