I'd like to generate a colored 'heat map' of readings from a hand-held sensor being moved around a room by a person.
I envisioned something like having two "measuring spools" (or ranging instruments), separated by a known distance, measuring the distance to the sensor.
If one knows the length all three sides of a triangle, how does one get the x,y coordinates of the sensor?
Any recommendations on:
- Other cost-effective or easy (out of the box) methods for achieving this result.
- Software for transforming a signal and x,y coordinates into a color image.
Thanks,
Rolfe
