DLP SDK Parameters

Other Parts Discussed in Thread: DLP-ALC-LIGHTCRAFTER-SDK

I am trying to understand SDK parameters which are supplied with examples.

Especially in the generation of patterns, there is a parameter like "region_count". This parameter affects region_size in gray_code.cpp also. What is exact equation of this parameter and what is it for?

Thank you

I am using DLP SDK 2.0 which is supplied through the link below

http://www.ti.com/tool/DLP-ALC-LIGHTCRAFTER-SDK

I am looking into example pattern generation source codes

C:\TexasInstruments-DLP\DLP-ALC-LIGHTCRAFTER-SDK-2.0\DLP-ALC-LIGHTCRAFTER-SDK\examples\generate_structured_light_patterns.cpp

Hi Mehmet,
region_count is not used in the present code flow.
Refer to gray_code.hpp , in GrayCode class there is parameter declaration
DLP_NEW_PARAMETERS_ENTRY( MeasureRegions, "GRAY_CODE_PARAMETERS_MEASURE_REGIONS", float, 0.0);

This is always set to 0 so in the gray_code.cpp region_count part of the code is not exercised.

Typical graycode pattern generated as per resolution of the camera or projector. For example - projector x resolution is 1024 then the pattern generator would add log2(1024) = 10 ; will generate 10 patterns.

I recommend going with default setting.

Sanjeev
