Method for distance measurement by means of a time-of-flight distance measurement system and a corresponding time-of-flight distance measurement system

摘要

Method for distance measurement by means of a time-of-flight distance measuring system (28), in particular a time-of-flight camera system (10), having an illumination (14) and a time-of-flight detector (22), in which, starting from a base PN sequence, which is used as a maximum sequence for the selection of an individual measurement is designed, a modulation signal (M ', M ") is generated for the lighting (14) and the time-of-flight sensor (22), a distance measurement (M) from at least three individual measurements with different phase shifts (Δφ) between the lighting (14) in the time-of-flight detector (22) consists where a temporal distance measurement sequence ((M, M, ...)) is generated with at least two distance measurements (M, M), and where exposure times for a measurement (M) result from the previous measurement (M) with associated exposure times The invention also relates to a corresponding time-of-flight distance measuring system (28).
