China’s lunar rover

But they'll just airbrush a clear picture of the object.

They don't even have to airbrush it - I have an off the shelf program here that will erase unwanted objects from digital images... surely the CCP has an equal or better program!

China Lunar Rover cams:

TCAM - Terrain Camera - 2350x1728 pixels in 22.9x16.9 deg

Dividing the angular field of view by the number of effective pixels in the image yields:

0.0097446808510638297872340255319 degree/pixel horizontal

0.00978009259259259259259259259259 degree/pixel vertical

Using the Visual Angle Calculator found at:

https://elvers.us/perception/visualAngle/

gives a pixel size of 0.4898 inch @ 2880 inches (80 yds) , or about a half inch per pixel at 80 yards for the TCAM.

I can't calculate the pixel resolution at a distance for the PCAM as I have been unable to find the dimensions in pixels to divide into the angular field of view, and I bet the image was taken with that PCAM camera.

They had to use the PCAM to find the distance, as it has two separated lenses to perform parallax calculations with to find distance. So, I bet that was the camera used to take the image, too. I've not been able to find either the pixel size OR the lens separation for that camera, and both of those are needed to calculate the pixel coverage at a distance in the first case, and to calculate the distance from a stereo pair of images in the second case. Since they already calculated the distance, the pixel size of the images is the more important one to uncover.
