Abstract
A multiple-pattern fiducial for a heterogeneous imaging sensor system. The multiple-pattern fiducial includes a first pattern detectable by a first wavelength of electromagnetic energy, and a second pattern detectable by a second wavelength of electromagnetic energy.
Claims20
A heterogeneous imaging sensor system, comprising:
- a multiple-pattern fiducial comprising a plurality of patterns detectable by a corresponding number of wavelengths of electromagnetic energy, the plurality of patterns comprising defined patterns of encoded information;
- a first imaging device to sense a first of the plurality of patterns, the first imaging device detecting a first of the number of wavelengths of electromagnetic energy;
- and
- a second imaging device to sense a second of the plurality of patterns, the second imaging device detecting a second of the number of wavelengths of electromagnetic energy.
