Abstract
A laser scanner for optically scanning and measuring an environment comprises a light transmitter having a predetermined transmission power for emitting a light beam. The emitted light beam is reflected at a measurement point in the environment. The reflected light beam is received with a certain intensity by a receiver. The transmission power is adjustable as a function of the intensity of the reflected light beam. Furthermore, a gray-scale value of the measurement point is determined as a function of the transmission power adjusted.
Claims13
A laser scanner for optically scanning and measuring an environment, comprising
- a light transmitter for emitting a transmitter light beam to a measurement point in the environment, and
- a receiver for receiving a reflected light beam reflected from said measurement point, said receiver being configured to provide a grey-scale value representative of the measurement point,
- wherein the reflected light beam has an intensity,
- wherein the light transmitter has a predetermined transmission power which is adjustable as a function of the intensity, and
- wherein the receiver is configured to provide the gray-scale value as a function of the adjusted transmission power.
A method of optically scanning and measuring an environment comprising the steps of:
- emitting a transmission light beam from a light transmitter to a measurement point in the environment, the light transmitter having a adjustable transmission power,
- receiving a reflected light beam reflected from said measurement point, the reflected light beam having an intensity, and
- determining a grey-scale value representative of the measurement point,
- wherein the transmission power of the light transmitter is adjusted as a function of the intensity, and
- wherein the gray-scale value is determined as a function of the adjusted transmission power.
