LIDAR
LiDAR (Light Detection and Ranging) systems provide high-resolution 3D maps of the environment. This section explains how LiDAR works, its advantages in object detection and obstacle avoidance, and the engineering challenges related to power consumption, cost, and integration with other sensor systems.

Radar
Radar is crucial for robust object detection in all weather conditions. This section discusses how radar sensors detect range and velocity, their importance in adaptive cruise control and collision avoidance, and how they complement other sensors in a fusion system.

Cameras
Cameras offer rich visual context and are indispensable for tasks such as lane detection, traffic sign recognition, and semantic segmentation. This section explores the roles of mono and stereo cameras, image processing pipelines, and their limitations in low-light or adverse conditions.

Ultrasonic Sensors
Primarily used for close-range object detection and parking assistance, ultrasonic sensors are cost-effective and reliable. This section delves into their working principles, limitations in dynamic environments, and integration in short-range fusion architectures.

GPS
GPS provides global positioning data, which is vital for localization and navigation. This section covers the role of GPS in autonomous driving, error correction methods, and how GPS data is fused with IMU and map data to enhance vehicle positioning accuracy.

Multisensor Fusion Architecture
This section presents an architectural view of how multiple sensor data streams are combined, filtered, and processed. It discusses data synchronization, time stamping, latency management, and the software pipelines responsible for creating a coherent perception of the environment.

Multisensor Fusion Algorithms
You’ll explore the core algorithms behind sensor fusion, including Kalman filters, particle filters, and Bayesian networks. The section explains how these algorithms are used to estimate object states, track motion, and reduce uncertainty in perception data.

Sensor Data Preprocessing
Before fusion can occur, sensor data must be cleaned, formatted, and synchronized. This section explains noise filtering, time alignment, and sensor-specific preprocessing steps to ensure the integrity of fusion outputs.

Sensor Calibration
Calibration is essential to align sensor data in a common reference frame. This section covers intrinsic and extrinsic calibration techniques, calibration toolkits, and the impact of miscalibration on perception accuracy.

Feature Extraction and Sensor Data Association
Feature extraction identifies critical elements in raw sensor data, while data association matches features across different sensors. This section details algorithms for extracting features (like corners, edges, and bounding boxes) and associating them for consistent tracking.

Probabilistic Fusion Algorithms
Here, you’ll learn probabilistic methods for fusing data under uncertainty. Topics include Kalman and Extended Kalman Filters, particle filters, and probabilistic occupancy grids—essential tools for robust tracking and environment modeling.
