tCam-Mini: Wireless thermal imaging camera based on ESP32

tCam-Mini is a small wireless thermal camera designed and developed by Dan Julio based on ESP32, which allows users to easily obtain and use radiation data through the Flir Lepton 3.5 sensor. It can obtain the temperature of each pixel and perform various types of thermal imaging analysis; it can also convert the data into color images to display the temperature and shape of the human body through thermal imaging.
tCam-Mini also comes with a desktop application out of the box that runs on Linux, Mac OS X and Windows systems. User-defined applications can easily communicate with tCam-Mini through a socket interface when running on any platform. During communication, commands and data are transmitted in the form of easy-to-parse json strings.
Hardware
Espressif ESP32-WROVER-E module (ESP32-D0WD-V3, 8 MB PSRAM, 8 MB flash), using PCB onboard antenna
Flir Lepton 3.5 (radiative LWIR camera with shutter, pixel 160 x 120)
CP2102N- A02 USB to UART, can control ESP32 Boot mode
Multi-voltage power supply (3.3 V, 3.0 V, 2.8 V, 1.2 V)
Two-color (red/green) status LED
Original Wi-Fi reset button
function
tCam-Mini camera is fully used All features of the Lepton sensor
Camera can operate in Radiometric/TLinear (each pixel contains temperature data) or AGC mode
Communicates with TCP/IP sockets using the json command set, simplifying custom applications communicating with the camera Interface
supports AP or STA Wi-Fi mode (static or IPV4 address provided by DHCP server)
Supports single image or data streaming mode
Controls sensor emissivity, gain and spot meter position
Cam-Mini's accompanying desktop application greatly simplifies The process of using cameras and data analysis. It has the following functions:
Display images or data streams with multiple palettes
Save in files Load images or data streams for later use or use in other applications. Can be saved in both image and video file formats.
Export images as jpg, png or tiff files.
Copy the current image to the computer clipboard.
Histogram display and analysis of pixel groups.
In one picture, multiple points will be displayed. Light meter and up to 4 markers representing temperature
Graphing functionality: Plots spot meter and marker data over time
Graphing Baseline mode: Allows comparing temperature to reference points in the scene (e.g. comparing temperature to blackbody constant )
Export the chart data to a text file for easy analysis by other programs and
print the chart (or save it as a PDF file on your computer)
