Camera stops streaming on changing camera resolution #166

Closed Harsharma2308 closed 4 years ago

Harsharma2308 commented 4 years ago

I want to change the resolution of a camera. On changing the camera resolution by calling cam.set_resolution((size,size)) The camera just stops streaming images.

I also try to plot images by -

img_rgb=cam_f.capture_rgb()

img_d=cam_f.capture_depth()
plt.imshow(img_rgb)
plt.show()

It just shows a blank black image. How do I set the camera resolution to be higher?

Hi, I haven’t tried set_capture_resolution()function But My solution is that

  1. Directly Change the resolution parameters of your camera in the scene first.
  2. Back to the code, call the cam.capture_rgb() then the output image will match the resolution you set in the scene.

To check the current resolution of your camera, you can call cam.get_resolution() Result is [width, height]

Sorry updated set_capture_resolution to set_resolution. Every time I set the resolution, that particular vision sensor gets paused I guess, and calling capture_rgb shows a complete black image. Other cameras do show the images on calling capture_rgb. I am also using rlbench. It starts working when I run some other command in the environment. So I cannot say if it is a PyRep issue entirely. Closing this for now.
