Slow camera display using opencv on i.MX8mPlus

[frk]

Hi,

I'm currently trying to use OpenCV with a mipi camera on i.MX8mPlus.

The goal is to display the video stream of the camera and interact with it through OpenCV (ie: pattern detection).

My main interrogation is about the video display that is very laggy.

Using Gstreamer or QT5 to display the camera stream, everything is smooth but using OpenCV add delay and lag.

Is there any way to accelerate OpenCV through the GPU or something else?

Hello frk,

IF you are connecting to mipi you must get at least 10fps with opencv if not then you must modify the driver, current driver are for mipi camera on OV5640 and OV2281.
