Abstract:
1. A method for the recording of an object space with an opto-electronic distance sensor by a signal propagation time method, comprising: transmitting optical signals using a transmitter; receiving optical signals reflected from objects located in the object space using a receiver device; deflecting optical axes of the transmitter and receiver device using a scanning device; ascertaining distance values from propagation time or phase angle of the optical signals transmitted using an evaluation device; splitting off from the beam in a beam path downstream of the scanning device part of the beam and delivering the part of the beam to the receiver device; ascertaining a pixel from signals of the part of the beam, the pixel being assigned an ascertained distance value and a space, wherein the receiver device includes sensors sensitive to one or more defined spectral ranges; calculating a temperature value from the signals of the sensors; and generating parallel to a distance image, a coincident thermal image.
