Bundle-Block and AT. What is the difference?

We were introduced to bundle-block adjustments in the last lecture. What difference, if any is there between aero-triangulation (AT) and and bundle-block?

My impression is that AT is a specific application of the bundle block adjustment, focusing on the intersection solution.

AT is suggested in research as the method to generate point clouds using computer vision from highly overlapped images from systems such as ultracam.

Am I on the right track?

Gimbal Lock

http://www.hq.nasa.gov/alsj/gimbals.html

This is a page I found that discusses gimbal angles and the singularities that can occur. The second part is a conversation between Apollo 11 astronauts and ground control. Thought I would share...

Multiple Rays

That is a good observation. They should be very close. I reverse engineered the curves from some incomplete documentation so there may be some errors in the definition/placement of the curves.

Homework 1

I noticed that if I varied my initial incoming ray around y=20.3 the focal length varied as well, but very little. I'm pretty sure this is to be expected, but I just wanted to check.

Yes

I will provide the on-campus students with a login to access the videos. You will receive an email early next week with that info. Of course you still need to show up for the class in person!

sharing the videos of proed

Dr Bethel can the videos of the digital photogrammetry class be shared in this blog?
I think that will help a lot of people who are beginners in photogrammetry and geomatics.

Greetings

All of the students in the course have (hopefully) been enabled as authors. You are encouraged to post questions and comments - and to reply to others' questions and comments. Was there something you hoped to see in the course outline, but didn't? Let me know if you have trouble getting access. See you on the Teevee.
