Description
Die Umrisspulsmodulationsmessung ist ein 3D-scan-Verfahren, dass mit Hilfe von Lichtlaufzeiten den Abstand eines jeden Pixels einer Kamera und die vom Pixel erfasste Oberfläche ermitteln kann. Die angedachten Einsatzgebiete sind die Robotik und der autonome Automobilbereich.The outline pulse modulation measurement is a 3D scan method that uses light propagation times to determine the distance of each pixel of a camera and the surface detected by the pixel. The intended applications are robotics and the autonomous automotive sector.
Die Umrisspulsmodulationsmessung besteht aus einer oder mehreren Kameras und einer oder mehreren Lichtquellen, die Lichtimpulse mit einer oder mehreren Lichtwellenlängen aussenden. Die Lichtimpulse sind der Aufnahme der Kamera zeitlich vor- oder nacheilend oder der Aufnahmetakt der Kamera ist zu dem Takt der Lichtimpulse abweichend.The outline pulse modulation measurement consists of one or more cameras and one or more light sources that emit light pulses with one or more wavelengths of light. The light pulses are the recording of the camera in time or lagging or the recording clock of the camera is different from the clock of the light pulses.
Mit dem zeitlichen Unterschied zwischen dem Aussenden des Lichtimpulses und der Kameraaufnahme wird eine Messtiefe vorgegeben.With the time difference between the emission of the light pulse and the camera recording a measurement depth is specified.
In der Kameraaufnahme unterscheidet man die Teile der Aufnahme, die unter dem Lichtimpuls Aufleuchten und denen, die nicht aufleuchten. So kann man unterscheiden, welche Teile der Aufnahme vor oder hinter der Messtiefe liegen.In the camera recording, a distinction is made between the parts of the recording that light up under the light pulse and those that do not light up. So you can distinguish which parts of the recording are before or after the measurement depth.
Für die Individualisierung der Lichtimpulsquelle werden Lichtimpulse gezielt ausgesetzt oder Lichtimpulspausen ausgesetzt oder die Wellenlängenabfolge der Lichtimpulse wird geändert.For the individualization of the light pulse source, light pulses are selectively exposed or exposed to light pulse pauses or the wavelength sequence of the light pulses is changed.
