DepthCapture example code issue

[amjad14]

After installing the binary for Voxel SDK and building DepthCapture.cpp, the executable doesn't perform any action.

Does it show any (error) message?

No, a command prompt window pop up and disappear.

Could you please run the executable from a command prompt? That will allow us to catch the error messages.

[amjad14]

it says required argument missing

[gadiyar]

You need to run the program from the command line with the following parameters:

DepthCapture.exe -v 0x0451 -p 0x9100 -f filename.bin -n 100 -t raw_processed

(replace the parameters as needed based on your board; the ones above are for the Haddock CDK, for capturing 100 frames of raw_processed data).

Thanks, it seems to work. But how the data is mapped inside .bin file?

It helped! but i'm still wondering the order in term of pixels of the Depth and amplitude data. I can see that I get for depth data 76800 (320*240) times 4bytes (float), but what about the order?

[amjad14]

I figured out the order.

for row = 1:240
for col= 1:320 Depthimage( row , col ) = A(k); // A is the float vector with the stream of data from binary file k=k+1; end
end

[hlprasu]

It is row-ordered depth data. Endianness is machine dependent.

Any information about the data order getting out of the line code on the right? f.write((char _)d->depth.data(), sizeof(float)_d->size.width*d->size.height);

Can I ask you how did you read .bin file generated from DepthCapture.cpp? I want to read bin file and pass it to opencv Mat
