High-Resolution Thermal Imaging with a Handheld
VIS+LWIR CameraJacob Hines Evan Wang
Motivation: High-resolution long wave infrared (LWIR) cameras areexpensive. The FLIR Lepton is a cheap LWIR camera module with limitedresolution. In this work, we build a VIS+LWIR camera that uses imagefusion to increase the resolution of the thermal image.

Goal and Methodology
Plan1. Use a Raspberry Pi Zero W to build the camera with the FLIR Lepton and the
Raspberry Pi Camera Module V2.
2. Compare and improve image fusion methods (e.g. Brovey, wavelet) on VIS+LWIR
dataset. Downsample LWIR, original is ground truth.
3. Implement final algorithm on completed VIS+LWIR camera.
Goal: Build a VIS+LWIR camera and implement an
efficient image fusion algorithm for real-time
streaming of resolution-enhanced thermal images.
