MappyDot Plus Field of View
The receiving SPAD array of the VL53L1x sensor includes 16x16 SPADs which cover the full field of view (FoV) of a scene. It is possible to program a smaller region of interest (ROI), with a smaller number of SPADs, to reduce this FoV.
The ROI is a square or rectangle defined by two corners: top left and bottom right. Four coordinates are used to localize these two corners on the full SPAD array:
The minimum ROI size is 4x4. An example of an ROI setting is given below:
The following image shows the coordinates of an object in the SPAD array compared to the location in the Field of View/Scene.
