Hi, I am using the TX2 onboard CSI camera to capture images, but find the image was very blurry in 640x360 mode. Please see the video here [url]http://www.artlystyles.com/tmp/cl_full.mp4[/url]. Any one know how to fix it? Is that because of the mode 640x360?
I won’t say it’s a blurry capture results, but it’s a motion blur.
please refer to the snapshot of your videos as below.
mostly of textures looks normally once the vehicle keep moving straight forward. External Media
it’s a motion blur while your vehicle is turning, or even drifting.
you should also note that, those ceiling light distortion were on the opposite way of your vehicle movements. External Media
may I know what’s the frame-rate settings you’re working with.
due to rolling shutter sensor capability, motion blur usually caused by scene change while programming a frame.
you may reduce the motion blur by increasing the sensor frame-rate.
thanks
it’ll depends-on requested surface aspect ratio and VI converter handle the scaling/cropping for results.
you may also found the information to indicate which sensor mode were used.
how about skip those image scaling operations, choose the 1280x720 sensor mode as your request surface for verification.
thanks
may I know which JetPack release you’re working with?
could you please execute gst-inspect to check the sensor capability.
for example,
$ gst-inspect-1.0 nvcamerasrc
assume you’re not based-on the latest JetPack release since we deprecated nvcamerasrc recently.
you might also check Topic 1056210, for the pre-built library to removes 120-fps frame rate upper bound limitation.
thanks
please refer to several comments and suggestions as below,
thanks
according to gst-inspect-1.0 results, there’s no frame-rate limitation for nvcamerasrc.
assume you’ll see the motion blur improvements by using higher frame-rate. could you please have confirmation that streaming with 60-fps is sufficient for your use-case.
besides frame-rate settings, suggest you should also keep exposure time as low as possible. please configure exposuretimerange to have fix values to check the results.
