Which approach is most advantageous to OEMs and Tier-1 automotive suppliers in autonomous driving?
The role of HD (High-Definition) maps has been central to most autonomous driving technologies for years. Many companies have invested significant resources in creating and maintaining these HD maps, believing they are a crucial component of the self-driving puzzle. At Imagry, however, we challenge that notion.
We have created the following comparison chart to demonstrate why going HD-Mapless makes sense for all aspects of the autonomous driving solution.
| Aspect | HD-Maps | HD-Mapless |
|---|---|---|
| Understanding the Road Infrastructure | Static representation; lacks real-time information (e.g., road construction, updated lane markings, etc.) | 
Real-time representation; constant scanning provides up-to-date information on dynamic road conditions. |
| Data Storage | Large storage requirements; impractical for most vehicles. |
No data storage required, as no external information is necessary. |
| Communication | Network coverage issues due to tunnels, network congestion, absence of cell towers, etc. Exposure to cyber vulnerability. |
No cloud-based connection is needed as the vehicle is self-sufficient.; it generates all data necessary for real-time motion planning |
| Localization and Perception | Location inaccuracies: leads to uncertainty in motion decision-making. Back-up perception system required to detect discrepancies |
Eliminate reliance on GPS and compass for localization. Real-time image recognition for safe and accurate motion planning |
| Cost and Resource Efficiency | Expensive solution; high initial investment and ongoing update costs |
Economical solution; camera-based approach is inexpensive and scalable. Cameras are typically pre-installed on the vehicle. |
| Relevance for Different Environments | Primarily designed for highway, urban, and suburban environments. |
Adaptable to various terrains and conditions; suitable for both on-road and unstructured off-road applications. |
Next stop, full autonomy!
