Issues when running Intel SDK samples with SR300 camera

[LFida]

Hello all!

I am running into some trouble trying to run the Intel SDK sample for the 3D cameras on a Macbook Pro 15" 2015 Model running Ubuntu 16.04. I installed all of th dependencies and optional packages successfully and downloaded the source code from the repository.

1) Tried to compile the samples from source (which succeeded), but I get the following error:

leandrogil@trinity92-macbook-ubuntu:~/Dropbox/University_BachelorInInformatics/Master4_Thesis/realsense_samples/samples/pt_tutorial_3/build$ ./pt_tutorial_3

terminate called after throwing an instance of 'std::runtime_error'

what(): camera is not support requested format

Aborted (core dumped)

Next, I compiled this sample with debugging symbols and ran the gdb debugger on it:

The program crashes at the following line in the main.cpp file:

...

// Initializing Camera and Person Tracking modules

if(pt_utils.init_camera(actualModuleConfig) != rs::core::status_no_error)

{

...

This init_camera(actualModuleConfig) call can be traced back to the common/utils/pt_utils.hpp file, where it references the following function/lines:

...

rs::core::video_module_interface::actual_module_config ConfigureCamera (rs::device* device)

{

...

if (streamModeNb >= streamModeCount)

{

throw runtime_error("camera is not support requested format");

}

...

}

...

Somewhere in this function I added the following line for debugging purposes, so that I can get the values with which it is trying to initialize the camera:

If you are using Librealsense, a general manual exposure and auto-exposure seems to be supported for both SR300 and R200 camera with the RS_OPTION_COLOR_EXPOSURE and RS_OPTION_COLOR_ENABLE_AUTO_EXPOSURE instructions. But instructions for fine-controlling the direction of the exposure seem to be limited to the R200 camera only.

Instead of fine-control over exposure, the SR300 instead has auto-range instructions.

The article is lengthy, so it is easiest to find the relevant instructions by doing a Find on the page for 'auto'.
