L1.2: Camera geometry

16 Oct 2018 Measuring distance to known objects using camera intrinsics

Important intrinsic equations

$u = f_x \cdot \frac{x}{z} + c_x$ $v = f_y \cdot \frac{y}{z} + c_y$

Camera calibration

Calibrate the camera using calibrate_stereo_1\left images.

Task details

Use camera intrinsic parameters to calculate distance to test object, which is depicted on images in folder distance (4 images). Original size of the object is 67,5mm.

To measure pixel size of the object use imtool (available also as Image viewer in Apps.
