Tearing image from camera sensor

[silencial]

I am running Carla in synchronous mode with fixed_delta_seconds=0.05. I attached a camera sensor on the vehicle to collect RGB images. The image size is 640*480. The image is saved as a nump array and visualized as below:

img = np.frombuffer(img.raw_data, dtype=np.dtype('uint8'))
img = img.reshape(640, 480, 4)
img = img[:, :, 2::-1]  # BGRA to RGB
plt.imshow(img)

However some images have this tearing problem as shown below: What could be wrong here and how should I fix this?

CARLA version: 0.9.15 Platform/OS: Ubuntu 20.04 Problem you have experienced: Tearing RGB image What you expected to happen: RGB image rendered correctly Steps to reproduce: Other information (documentation you consulted, workarounds you tried):

You can try saving the numpy array and see if it has the same problem.

# pillow
from PIL import Image as PILImage

cam_image = PILImage.fromarray(np_array)
cam_image.save(file_name) # change file_name

You can do the same with the image class from calra

img.save_to_disk(file_name)

Hi @silencial, have you been able to verify that the saved images or saved data have the same tearing problem?

Actually I was saving the data with the PIL.Image.fromarray() method and plotted it afterwards. And the tearing problem was there. I have not tried saving the image directly with the CARLA method. Will test later.

I am closing this issue as there has been no more feedback. If you try the CARLA method and it still doesn't work, feel free to reopen the issue.
