TIME OF FLIGHT CAMERA SYSTEM

摘要

A light propagation time camera system and a method for operating such a system, in which—in a distance measurement a first range-related variable is ascertained using a phase shift in an emitted and received signal for a first modulation frequency,—and in a control measurement a second range-related variable is ascertained, wherein the control measurement is performed at a second modulation frequency, which differs from the first modulation frequency, and the control measurement is performed with a smaller number of phases than the distance measurement is provided.

1. A method for operating a TOF camera system which can be operated with at least two modulation frequencies, wherein
in a first distance measurement, a first range-related variable is ascertained on the basis of a phase shift of an emitted and received signal for a first modulation frequency, and in a second control measurement a range-related variable is ascertained, the control measurement being carried out at a second modulation frequency which differs from the first modulation frequency, and the control measurement is carried out with a smaller number of phase positions than the distance measurement.
