Article by Limarc Ambalina | September 03, 2019

Autonomous vehicle development is one of the fastest-growing fields of machine learning. With companies like Google, Uber, and Tesla leading the market, the field is also one of the most competitive fields in AI. To help your self-driving vehicle become a key player in the industry, any edge you can find over your competition is crucial. The edge Lionbridge offers is the outsourcing and scalability of image annotation, so that you can focus on the bigger picture.

Lines and Splines for Lane Recognition

Annotate road lanes, shoulder lanes, and sidewalks for boundary and lane recognition in autonomous vehicles.


How Lionbridge Provides Image Annotation for Autonomous Vehicles - Semantic Segmentation

Semantic Segmentation for Scene Understanding

Associate every pixel in an entire image with a class label. Segment traffic images into important categories i.e. road, street lamp, pedestrian, vehicle, building, sky, etc. to aid in scene understanding. 


Other In-demand Image Annotation Services We Provide:

  • Image Classification / Image Categorization
  • Landmark Annotation
  • Pixel-precise / Pixel-wise Segmentation
  • Polygons

Safety and Security

How Lionbridge Provides Image Annotation for Autonomous Vehicles - safety and security

At Lionbridge, we take data security very seriously. Depending on the needs of your project and the sensitivity of your content, we can provide custom workflows with varying levels of security protocols. 

Remote Staff

We have a large, vetted, and trained crowd of 500,000+ staff ready to work on your image annotation project. Every member of our SmartCrowd™ signs an NDA when hired by Lionbridge. If your project has stricter security requirements, we can work with you to draft a custom NDA.

Temporary On-site Staff

Depending on your office location, Lionbridge can provide on-site staff for image annotation. If your project has specific needs that can’t be met with remote staff, our dedicated on-site staffing solution may be the best option for your project. 


Free Consultation 

We take a client-focused approach to creating training data. Our sales team will first make sure we thoroughly understand your needs, budget, and business model before creating the perfect solution for your project. 

Once we understand your goals, needs, and standards of quality, we execute a small trial cycle. This trial cycle is done as a proof of concept to make sure our data production, quality assurance, and deliverables meet your standards before we get to work on the entirety of your project.



While this article focuses on Lionbridge’s image and video annotation services for autonomous vehicles, we also provide image annotation services for other areas of machine learning. Learn more about how Lionbridge can help your project be an industry-leading success.
