the array index out of range

[chenshida]

I have study struct light recently, and useing this code, it can generate point cloud data with you given test data.but when I use myself data, the code can not work and it will raise in this code
bkts[vec2Idx.x * projHeight + vec2Idx.y].push_back(getRay(i));
I find that this calculate will cause array index of bkts out of range and code running exception.
On my occasion, I use projector resolution 912x1140, and the camera resolution is 1280x1024, and camera calibration is well done.why this problem occur? the code just support projector resolution 768x1024?

It should work fine with any resolution. We have tested it on projectors with 2 different resolutions.
Have you tried the CPU version?

Also if it is possible, could you send me the data you used, I will take a look when I get a chance.

Have a great day!

I`m already use CPU version.
could you give me an email ,I package my dataset to you.
Thanks.

I also get the same error.
If the problem is resolved, please respond.
And what is the resolution of the projector to use as a parameter?

my configuration is widows 10, visual studio, cpu version, data is alexander.

Hey there!
I have the same problem. I'm trying to process some images using a GoPro hero 3+ camera and a portable projector (resolution 800x600). If I set width=800 and height=600 I obtain a "segmentation fault". If I use the default parameters (1024x768) it works but the point cloud is clearly wrong.
Can someone please help me?
Thanks a lot

This problem maybe a bug for Convert bitarray to gray code. In header file "DynamicBitset.h" , function "glm::uvec2 to_uint_gray ()", this code use a static bit convert like this

unsigned yDec = num & 0x3FFU;
unsigned xDec = num >> 10;

but in fact , it is deside by you projector resolution. in my situation, my projector resolution is 912x1120, so is like this:

unsigned yDec = num & 0x3FFU;
unsigned xDec = num >> 11;

for reference only, not guaranteed to be accurate
