INTRODUCTION

Cameras are commonly used with robots. To interpret camera data for purposes of navigation or grasp planning, one needs to interpret patterns of pixel values (intensities and/or colors) and associate labels and coordinates with these interpretations. This chapter will introduce conventions for camera coordinate frames in ROS, camera calibration, and low-level image-processing operations with OpenCV. Extensions to 3-D imaging are deferred to ...

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
