Procedure for measuring distance by means of a light-time remote sensing system and corresponding light-time remote sensing system

摘要

Method of measuring distance by means of an illumination (14) and a light-time detector (22) having a light-time distance measuring system (28),where a modulation signal (M0',M0') is generated from a base PN sequence for the illumination (14) and the light duration sensor (22), a distance measurement (Mt) consists of at least three individual measurements (Et,1,..., Et,n) with different phase shifts (Df) between illumination (14) in light duration detector (22),where each phase-shifted unit load measurement (Et,i) is assigned a separate exposure time (T,ui)),with a time measurement sequence ((M1, M2,...)) is produced with at least two distance measurements (M1,M2),and where exposure times (ft+1) for the phased displaced individual measurement (Et+1,i) for a measurement (Mt+1) from the previous measurement (Mt) with associated exposure times (Tt) of the phased displaced individual measurement (Et,i)${\overrightarrow{\tau }}_{t+1}=\overrightarrow{F}\left(M_t,{\overrightarrow{\tau }}_t\right).$
