Hi @utkarshrai2

Gaps is the distance of the balls to each other.
Big Gaps is the distance between the columns.
Important note : The Bubble dimensions is important when you measurement of Gaps and BigGaps

Hey, when I try to run this on my local system with the sample you had in https://github.com/Udayraj123/OMRChecker/tree/master/inputs/OMR_Files_Sample/CityName/HE folder, I am getting "Segmentation fault (core dumped)" error.

I am looking for an automated evaluation of OMR sheets. Have attached sample file for which I need to solve this. Don't know where to start for processing this. Is there any doc for the same?

[Udayraj123]

Hi @Siva2406,
You can check this section in the readme.

[Udayraj123]

Please create a new issue for discussing your code error.

Note for others: Here's the issue created [SOLVED]

[utkarshrai2]

Hi Uday nice repo.
Could u explain the difference between gaps and bigGaps?

[utkarshrai2]

I want to use some custom OMR_Marker, are there any marker specific constants in the code. Because i am having some spacing issue when i am setting the layout with a custom marker

Hi @utkarshrai2

Gaps is the distance of the balls to each other.
Big Gaps is the distance between the columns.

But we are setting origin for each column separately, so whats the utility of bigGap

[Udayraj123]

If you could share a sample image and the marker on your forked repo, we can help you configure it

[Udayraj123]

@utkarshrai2 there are multiple ways to set the same grid layout. Biggaps help you do it in a minimal way.
Especially when the layout is a grid of small grids(Qblocks). Biggap is the gap between those Qblocks. Hope I'm clear

Hi @Udayraj123 I tried to configure the grid layout but unable to get the perfect match. Let me know if you could help

Hi Raj,
How did you create those GIFs ?

[purusello]

Sorry for my english. I want know if I can use scanned images without border. When I use them I get the message "Paper boundary not found! Should you pass --noCropping flag?" If I use --noCropping, did I need the marker icon ?

Thanks

[olzenkhaw]

I have tried not to use the marker icon with --noCropping, it still work perfectly with scanned images. The scanned images must be the same size, same orientation etc...

[Udayraj123]

@purusello yes you need the noCropping flag. And marker icon is not necessary to use, to skip using it simply remove the "marker_path" entry from your template.json

[Udayraj123]

@balaji-ch the GIFs were created using a small script which is no more part of the codebase :)

[Udayraj123]

@vijuc895 if you are still facing the issue, head over to the Discord group for quicker help! Link is in Readme

[purusello]

@purusello yes you need the noCropping flag. And marker icon is not necessary to use, to skip using it simply remove the "marker_path" entry from your template.json

If some scanned paper is distorted, why don't to use the marker to adjust, what do you think @vijuc895 ?
