Superior Sensor Fusion

Enabling Safer Navigation

Based on LeddarTech’s comprehensive and demonstrated sensor data low-level fusion expertise, LeddarVision’s AI based software processes sensor data at a low level to efficiently achieve a reliable understanding of the vehicle’s environment required for navigation decision making and safer driving. LeddarVision resolves many limitations of ADAS architectures based on legacy object-level fusion by providing:

  • Scalability to AD/HAD
  • Flexible modularity to effectively handle a growing variety of use cases, features and sensor sets
  • Centralized, hardware-agnostic low-level fusion, which optimally fuses all sensors for higher and more reliable performance

Low-level sensor fusion utilizes information from all sensors for better and more reliable operation. As a result, this sensor data low-level fusion and perception solution provides superior performance, surpassing object-level fusion limitations in adverse scenarios like occluded objects, objects separation, camera/radar false alarms, blinding light (e.g., sun, tunnel) or distance/heading estimation.

  • The most accurate 3D environmental model, object detection and classification
  • Based on low-level fusion of sensor data with upsampling
  • Single development platform for optimized cost-effectiveness and scalability
  • Sensor-agnostic – Combines data from LiDAR, radar and camera
  • Provides LiDAR performance levels using only camera + radar in Level 2 applications
  • Improves Level 3+ LiDAR performance and cost

LeddarVision for Automotive

Implementing and commercializing a comprehensive, scalable end-to-end perception program to support all levels of ADAS in the automotive market is known to be highly challenging. LeddarVision makes your vision a technical and commercial reality with groundbreaking fusion and perception innovation that democratizes the deployment of advanced, cost-effective ADAS and AD features, enabling safer and smarter vehicles under increasingly complex driving scenarios.

Scaling from a front-view family of products to surround-view and parking assist, LeddarVision is designed to enable not only L2/L2+/L3 ADAS but also a 5-star safety rating (ADAS) for new car assessment programs (NCAP) and general safety regulations (GSR).

With the LeddarVision software stack, OEMs and their Tier-1 and Tier-2 suppliers are able to leverage a scalable, unified platform that resolves key sensor fusion and perception challenges, improves ADAS performance and accelerates time-to-market. LeddarTech has strong domain expertise and a complete, demonstratable work process to bring your technology integration from concept to practice.

Automotive applications enabled by LeddarVision include highway assist (HWA), park assist, adaptive cruise control (ACC), collision warning systems (front and rear), automated emergency braking (AEB [C2C and VRU]), lane keep assist (LKA), lane change assist (LCA), speed assist (SA), blind spot detection (BSD), traffic light recognition (TLR), traffic jam assist (TJA) and driver-initiated automated lane change.

LeddarVision Perception Framework

To create a highly accurate environmental model for safe and reliable autonomous driving, multiple processes must work in sync. Below is a high-level view of our environmental perception software framework. The process starts with the raw data received directly from the vehicle sensors via software API, and ends with complete environmental model data that is passed to the AV driving software module.

Step 1

Low-level data fusion and upsampling algorithms constructing a high-definition 3D RGBD model

Calibration, unrolling and matching module receives raw sensor data before synchronizing and fusing it into a unified 3D model. Upsampling increases the effective resolution of the distance sensors, resulting in a dense RGBD model with each pixel containing both color and depth information. Localization and motion tracking help to determine the self-position and velocity.

Step 2

Applying context-aware algorithms on the 3D RGBD model to achieve perception

Frame-based object detection and segmentation of the road include obstacles, vehicles, pedestrians, bicycles, motorcycles, lane borders, available free space and more. Detection by classification is performed with DNN-based algorithms that require training. In parallel, detection without classification is performed by another set of algorithms, thus enabling the detection of unexpected obstacles. Multiframe object tracking includes 3D modeling, motion tracking and sizing of each object.

Step 3

Creating the 3D environmental model

The resulting environmental model data is accessed via our software API and includes an occupancy grid and list of parameters for any tracked objects: localization, orientation, motion vector and more.
