We developed a solution such as: Sensor fusion, Localization.

Company Background

Civil Maps is a San Francisco based start-up that provides a scalable, edge based HD mapping and localization platform that helps automotive OEMs, map providers, and mobility companies accelerate their autonomous driving programs. With their Edge MappingTM technology, Civil Maps is redefining traditional map creation workflows and enabling continental-scale base map crowdsourcing. Civil Maps’ resources are augmented through its partnerships with the leading geospatial, governmental and academic institutions including U.S. Department of Energy, National Energy Research Scientific Computing Center, Verizon Innovation Program, University of California Berkeley and Stanford University. The Transformative Solution Civil Maps provides autonomous vehicles with cognition, enabling them to crowdsource 3D maps and make better decisions for safe driving. They approached Tech Vedika to build a solution that would provide real-time, localization in six dimensions and producing augmented reality maps to be used by autonomous vehicles and humans.

Autonomous driving is the highest level of automation for a vehicle, which means the vehicle can drive itself from a starting point to a destination with no human intervention. The problem can be divided into two separate tasks. The first task is focused on keeping the vehicle moving along a correct path. The second task is the capability to perceive and react to unpredictable dynamic obstacles, like other vehicles, pedestrians, and traffic signalization.Tech Vedika developed a solution with the following self-driving car components:

1. Computer Vision & Machine Learning
2. Sensor fusion
3. Localization

The Transformative Solution

The computer vision and machine learning module is used to perform
the following basic operations from the images captured by the camera:

  • Detect dynamic objects like vehicles and pedestrians
  • Detect the distance to the object and obstacles
  • Detect traffic symbols and signals
  • Recognize the traffic symbol information and Signals
  • Perform localization


An autonomous vehicle must be equipped with a set of sensors that
allows it to accurately determine its position relative to the road limits.
The lateral deviation is the most critical since it must be in the order of few centimeters. To achieve the stringent level of accuracy, integrity,
and availability, required for autonomous driving applications, Tech
Vedika used 3D LASER scanners (LIDAR) and cameras. Computer vision
and optimization modules are used to compute the changing
pose of the camera with respect to LIDAR and the GPU & IMU unit.

The Results

Tech Vedika developed an advanced vehicular cognition system which
provides centimeter-accurate Localization in six degrees of freedom.

Innovation

  • Very accurate and fast dynamic pose estimation of the camera(translation and orientation) with respect to LIDAR.
  • Very accurate and fast dynamic pose estimation of the LIDAR unit (translation and orientation) with respect to the GPU & IMUunit.
  • Detection of pedestrians and vehicles.
  • LIDAR based object detection of 3D surfaces and Lane markings.
  • Text & number recognition: car licence plate recognition, address or road number recognition, etc.
  • Semantic information extraction using LIDAR and Camera
  • Accurate estimation vehicle position in the global co-ordinate system using particle filters.
