Detection of three-dimensional information with a projected plane of light |
摘要 |
An object is scanned first with a light plane from a variable-intensity light-plane projector, and the reflected light is used as signals to modify point by point the output of the projector in accordance with the intensity of the respective reflective-light signal. Thereupon the object is scanned a second time and the projector is instructed to apply less light than before to those points of the object from which a strong reflected-light signal was received during the first scan, and/or to apply more light to points from which a weak reflected-light signal was received during the first scan. In similar manner, a projected intensity encoded light volume is projected on an object and the reflected light is used as signals to point-by-point modify the output of the projector for subsequent projections.
