Raw images extraction

[bor_o]

Hello, I am confused regarding the extraction of raw images from SVO files. Could you please clarify a few questions on this topic?

I have two ZED mono cameras and create a virtual stereo pair from them. I save the data from them by recording in ZED Explorer.

Is it possible to extract the raw (unprocessed) image from an SVO file? I have heard that extracted images are rectified.

How does the calibration file influence these images?

Is there way two save save raw images, for example without creation virtual pair ?

Are you saving monocular or stereo SVO files?

This depends on how you retrieve the information.
The SVO file contains RAW image streams; you extract the images by using the retrieveImage API function, like you normally do with a live camera.

To extract rectified images, you must use the sl::VIEW::LEFT or sl::VIEW::RIGHT parameter.
To extract unrectified images, you must use the sl::VIEW::LEFT_UNRECTIFIED or sl::VIEW::RIGHT_UNRECTIFIED parameter.

Please read more on the API documentation: C++ / Python

Hi @Myzhar
I am saving stereo SVO files.

To extract rectified images, you must use the sl::VIEW::LEFT or sl::VIEW::RIGHT parameter.
To extract unrectified images, you must use the sl::VIEW::LEFT_UNRECTIFIED or sl::VIEW::RIGHT_UNRECTIFIED parameter.

Thank you, I missed that option.
