Problems with Camera properties

[Mildred Espinosa]

Dear Dr, Corke:

I´m a Master´s in mechatronics student, and  recently purchased your book and had dedicated quite time going trough the Vision section (Chapters 11-15) and I have faced a lot of issues with the toolbox, I had tried all the ways suggested on the group and so, but still couldn´t get the results showed in your book.

The supporting group has helped me though, I had been able to get some issues fixed like SE3 not working and the check issue while using mkgrid, however right now I am stuck with some camera functions, I am not able to get the translation feature to work, it seems not to be working with the "cam.project" command, and I can´t figure why, even if I had been able to get other features working because of this transl not working I keep getting null values on my matrixes and consequently all the other operations will fail.

Right now I am using MAtlab R2020b

I´m attaching some pictures as well, I am trying the code from the book page  255.

Thank you.
