Camera Pose Estimation

Given a map contians street-view images and 3D data (e.g. lidar, SfM point cloud, or depth), estimate the 6 DoF camera pose of a query image.

• Input of the system: query image, reference image and lidar point cloud, where reference image and lidar are known in a global coordinate system.

• Output of the system: 6 DoF camera pose of the query image in the global coordinate system.

Note: 6 DoF camera pose mean 3 DoF translation and 3 DoF rotation along x, y, z axis.

Code & Files

1. Dependencies & environment

• Matlab 2016b
• OS: Ubuntu 16.04 (should work on other platform too)

2. My project files

(Note: the hyperlinks only works if you are on the homepage of this GitHub reop, and if you are viewing it in “github.io” you can be redirected by clicking the View the Project on GitHub on the top)

• main.m is the main code for this demo.

• read_pose.m read camera pose.

• read_lidar_binary.m read lidar bianry file.

• ref.m is the class of reference image.

• world2Image.m is the function of project points from world to image.

• test folder contains the test data.

• source folder contains the example images.

3. How to run the code

(1) Install Matlab (tested with 2016b and 2017a).

(2) Set your current path to this demo and run main.m.
