Master Thesis - Depth-Augmented COLMAP for Sensor-to-Sensor Extrinsic Calibration (m/f/d)

Full-time

Software Engineering

Introductory information

This thesis investigates how depth information can be integrated as an additional geometric constraint into a COLMAP-based calibration pipeline. The goal is to improve camera-to-camera and camera-to-LiDAR extrinsic calibration by combining image-based reconstruction with depth consistency. A key part of the work is the design and evaluation of a custom loss function for depth-augmented calibration.

Depending on the achieved results, this thesis may contribute to a scientific publication in computer vision, robotics, or autonomous systems.

Your Role

Develop and evaluate a depth-augmented COLMAP-based calibration approach.

Design a geometric loss that combines reprojection error with depth consistency.

Compare the method against standard image-only calibration.

Evaluate robustness under challenging conditions such as low texture, small overlap, dynamic objects, or noisy depth data.

At a minimum we’d like you to have

Good programming skills in C++ or Python, and willingness to work with both.

Interest in computer vision, 3D reconstruction, and sensor calibration.

Familiarity with Linux-based development environments.

Basic understanding of camera geometry.

It’s preferred if you have

First experience with COLMAP or similar 3D reconstruction tools.

Basic experience with OpenCV, point clouds, or numerical optimization.

Interest in multi-sensor calibration and real-world sensor data.
