CV2018-01-31.zip), find the effective focal length of the camera and the horizontal field of view. See calculating focal length.
The squares of the target board are 3 inches in size. The MATLAB code below lists the nominal distances of the camera to the target (with an unknown fixed offset)
z = [4:2:20 20 22:2:28]*12; % units are inches
ginputto get three arbitrary points and then produces the diagram shown below. As an extra challenge, superimpose this figure over an underlying image, using color to make the annotation stand out. Use
axis equalto insure the same scale in both x and y directions.
plot3to draw a sprial similar to that shown below. Then show an orthographic projection. (see vis1.m)
You will need his Robot and Vision toolboxes from his toolboxes page. Documentation for the toolboxes may be found in Machine Vision Toolbox Reference and Robotics Toolbox Reference
