onsemi – High Performance Vision & Sensing for Next-Generation Drones

Sensing Systems

Modern drones rely on advanced sensing systems to perceive their environment, capture/stream high-quality images and navigate autonomously. By combining image sensors, depth sensing, and intelligent processing, drones can provide a vast aerial view, detect obstacles, map surroundings, and operate in complex or low-visibility environments. onsemi's imaging and sensing technologies provide the foundation for reliable perception—enabling safer flight, higher accuracy, and greater autonomy.

What Makes Up a Drone Sensing System

A drone sensing system is composed of multiple sensing and imaging layers that work together to deliver perception, image streams and navigation.

Navigation System

• Multi-camera systems provide self-awareness
• Depth sensing enables obstacle detection and distance measurement
• Sensor fusion combines vision with GPS and inertial data
• Enables collision & obstacle avoidance, Supports autonomous navigation, SLAM, and obstacle avoidance

Vision System

• High-resolution video capture with purpose-oriented images
• Efficient streaming of captured video to ground control at optimized bandwidth

Advanced Sensing Technologies

• Depth sensors (iToF) for 3D mapping and spatial awareness
• SWIR imaging for operation in low light, fog, or obscured environments
• Thermal imaging for beyond visibility and through opaque surfaces
• Complementary sensors (LiDAR, ultrasonic, radar) for enhanced perception
