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.

[Siva2406]

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]

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

[andreemidio]

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

[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

[utkarshrai2]

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
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 ?
