Example Embodiment

[0037]First of allfigure 1 .

[0038]It shows systems 2 for simulating LIDAR sensors in a virtual environment.

[0039]Virtual reality, or simply referred to as VR, indicating the representation of reality and its physical attributes in real-time virtual environments generated by the computer.

[0040]In order to create an immersion, a specific output device (such as a virtual reality headset) is used to represent the virtual environment. In order to give space impression, two images are generated from different angles and indicated (stereo projections).

[0041]In order to interact with the virtual world, a specific input device (not shown) is required, such as a 3D mouse, a data glove or a flying rod. The flying rod is used to navigate through an optical tracking system, wherein the infrared camera is permanently informing the system 2 by capturing a mark on a flying rod, so that the user 8 can move freely without a cable. Optical tracking systems can also be used to capture tools and complete b

Abstract

The invention relates to a method for computer-implemented simulation of a LIDAR sensor in a virtual environment, the method comprising the following steps: (S100) reading a virtual reality data set (VR) representative of the virtual environment, (S200) reading a parameter data set (PM) for parameterizing a LIDAR sensor simulation module (4), (S300) creating a laser beam data set (LD) representative of laser beams (LS1, LS2, LS3, LS4 and LS5) emitted by the LIDAR sensor by using the LIDAR sensor simulation module (4) and the parameter data set (PM), (S400) determining a path distance data set(RD) representative of the path distance of the laser beams (LS1, LS2, LS3, LS4 and LS5) by ray tracing evaluation of the virtual reality data set (VR) and the laser beam data set (LD), and (S500) creating image data (BD) representative of the virtual environment by combining the virtual reality data set (VR) with the laser beam data set (LD) and the path distance data set (RD).
