Distance Visualization With Multiple SPAD areas in VL53L1X Time-of-Flight sensor
-
This example illustrates how to get information from multiple SPAD areas from VL53L1X TOF sensor. 16 Regions Of Interest(ROI) with size of 4 * 4 SPAD elements each are defined in SPAD sensor array. Thus, a 4 * 4 measurement matrix formed. Distances measured from each of 16 ROI, interpolated to 8 * 8 image and displayed as Thermal like image.

hi, wich ino file I have to upload to visualize "thermal distance?
