Software Package
The LeSonar 2 comes with comprehensive demonstration software to immediately showcase its capabilities:
2D Slicing Camera
Real-time visualization of the energy landscape at specific distances, allowing precise object detection and tracking within a 2D plane.
3D Energy Visualization
Full three-dimensional point cloud representation of reflected acoustic energy, providing comprehensive spatial awareness of surrounding objects.
Both examples are implemented in C99 using Raylib and Sokol libraries for efficient real-time 2D/3D visualization, offering excellent performance while remaining accessible for customization.
Potential Applications
Robotics
High-resolution obstacle detection, mapping, and navigation for autonomous robots in various environments.
Entomology
Detection and classification of flying insects based on wing beat patterns and acoustic signatures.
3D Scanning
Non-contact measurement and modeling of objects using ultrasonic reflections for various industrial applications.
