Internship | Computer vision for robust image matching on high-resolution highway data

The Intelligent Imaging department at TNO works on a large variety of computer vision solutions in the field of inspection. One of these projects is the automated inspection of the Dutch highways, where our algorithms are used to monitor the state of the highways and to indicate when sections of highway need to be repaired or replaced. Every year, a high-resolution 3D scan is recorded of all Dutch highways (approximately 15.000 km worth of highway lanes). Our task is to extract as much information as possible from this extremely large amount of data. Currently, different categories of road damage are already automatically detected such as cracks or absolute wear. However, it is challenging to accurately (millimeter precision) re-locate the same piece of asphalt from each year’s recording as the GPS data of the measurement vehicles only have a precision of several meters. During your project, you will create an algorithm that can perform such accurate matching based on a series of images.

You will investigate different methods capable of the abovementioned matching problem. This research will include a literature review of the current state-of-the-art of both classical computer vision approaches as well as deep learning solutions. Afterwards, you will investigate the remaining difficulties that these algorithms have specific to the considered use-case of matching pieces of road over time, and creating a new algorithm that is able to deal with a number of practical problems, such as: change of road condition (general wear, cracks, etc.), different measurement conditions (e.g. weather conditions) or repairs (e.g. repaired cracks).

You will perform this assignment in the Intelligent Imaging department. TNO’s Intelligent Imaging group is specialized in image processing, image enhancement, image analysis, visual pattern recognition, artificial intelligence and deep learning. This young, passionate, creative and committed group (50 people) works with partners on technological breakthroughs for innovations in important societal and economic themes, developing knowledge in various research areas including both AI (e.g. learning with less data or hybrid AI) as well as crucial non-AI knowledge, real-time algorithms, edge processing and information fusion.

The project duration is flexible, but preferably within the range of 6 to 12 months. Please mention in your application whether you are looking for an internship or a graduation project, the preferred length of your project and your desired starting date. When doing an internship/graduation project at TNO you will receive an appropriate internship fee.

Keywords to describe this project include: Artificial intelligence, Computer Vision, Image Matching, Deep Learning, Machine Learning, Road Inspection, Highway Pavement Inspection.

You are in the final stages of your master’s degree in artificial intelligence, computer science, physics, mathematics, electrical engineering, or a similar degree, you have experience in programming (e.g. Python or Matlab) and preferably have some prior experience with computer vision and/or image processing algorithms.
