Camera Properties #76

Closed acvictor closed 5 years ago

What's the field of view of the camera lens used here?

mcordts commented 5 years ago

Hi, you could compute that based on the calibration data provided. Please refer to the Readme and docs in this repo.

acvictor commented 5 years ago

Size of the sensor d = 5.8 mm Pixel size = 2.2 µm Focal length f = 2262 x 2.2 µm = 4.9764 mm

FoV = 2arctan(d/2f) assuming the lens is focused at infinity = ~60°

Does this seem correct?

That sounds reasonable!

How can I get the Focal length f, i.e.2262 and 2.2. Thank you!

Hi,

Could you please tell me where the camera folder? In calibrationpfd it is said that the intrinsic and extrinsic parameters are in the camera folder. Thank you

acvictor commented 5 years ago

@jilner I got those values by looking up the sensor they used.
