Is there any way to import a .dxf file with open cv?

edit

Thank you for your quick answer. Do you have an idea for an external programm?

not at all, sorry.

(point is, that your dxf might not even contain a 2d image, only "drawing commands")

I think I do not need a real 2d image. I want to make a pattern matching with the shape, which is stored in dx. format.

sure, if you can extract the shape, you probably should do so, and match it against another shape later.

pattern matching is a different beast though, and needs 2d images to work on.

okay you are absolutly rigth I'm sorry for the missunderstanding. But nervertheless I can't get the shape from the dxf file with opencv rigth?

if you have an image, you can extract contours from that via findContours() or houghlines()

opencv just cannot process dxt files directly (proprietary file format)

So if i could convert dxf into bmp for example. I could make a shaope analysis with tthe bmp file in opencv

yes. you can use shape or template matching, then.

okay thank you very much !

Do you know wether there is some way to convert a dxf file to bmp jpeg etc.? Searching for hours but didn't find something usefull. I have to implement it into a give software in c++ ...
