A Pi camera is mounted 2 meters from the ground plane and
with pitch angle = 0 Focal length = 3.6mm Detector size =
3.76 × 2.74 mm Resolution = 2592 × 1944 pixels
a. Plot a graph of the mapping between the longitudinal distance
from the camera of points on the ground plane their position on the
image plane. How far out can the camera see?
b. At the furthest longitudinal distance that the camera can see
(answer of 1.a.i), plot of a graph of the mapping between the
lateral distance from the camera of points on the ground plane
their position on the image plane. How wide can the camera see?
c. Determine the ground-plane straight line equation of the
following straight line on an acquired image:
4 column = -row + 100, row > 1, column 21 3
Top view X-axis Side view Y-axis (0,0) (0,0) Z-axis Z-axis Camera Camera Image plane Y-axis 2m Column = 1 Row = 1 Column = 2592 X-axis (0,0) Ground Plane Row = 1944 Figure 1: Pi camera set-up Note: In reality, the image plane is actually rotated 180° around the X- and Y-axes before being resented to the viewer. In this problem, however, we are not doing this rotation.
