Embodiment Construction

[0068] In the following figures, the same reference signs are also used for the same technical features of different embodiments.

[0069] exist figure 1 The method according to the invention for operating a lidar system 1 for surroundings detection in the field of view FOV of the system 1 is schematically visualized in .

[0070] In this case, according to a first step, a detection 101 of at least one detected temperature which differs from the load temperature in at least one light source 2 of the system 1 takes place. Furthermore, according to a second step, an evaluation 102 of the load temperature is carried out by means of an analysis function based on the detected temperature. In this case, steps 101 and 102 can also be combined in step 122 , in which a model-based evaluation is carried out on the basis of a thermal model. The model can be designed to reduce deviations caused, for example, by thermal resistances. According to a third step, the specification 110 of op...

Abstract

A method for operating a LiDAR system for an environment detection in a field of view (FOV) of the system, wherein the following steps are performed: detection of at least one temperature measurement, which differs from a loading temperature in at least one light source of the system, estimation of the loading temperature based on the temperature measurement using an evaluation function, specification of an operating limit, which is specific for the maximum thermal load capacity of the light source, provision of a preset for at least one region of interest (ROI) in the field of view (FOV), adaptation of an operation of the system, and based on the preset for the region of interest (ROI) and the estimated loading temperature and the operating limit.

Description

technical field [0001] The invention relates to a method for operating a LiDAR system for surroundings detection in the system's field of view. Furthermore, the present invention relates to a system and a computer-readable storage medium. Background technique [0002] It is known from the prior art that lidar systems are used in vehicles for surroundings detection in order to be able to detect the vehicle surroundings with a long range and high positional differences. In particular, lasers can be used for this purpose, the emitted laser beams of which are deflected by mirrors or other deflection units in order to carry out the detection for different horizontal and / or vertical positions. In this way, a two-dimensional or three-dimensional field of view of the surrounding environment is created in which objects can be detected by the system. [0003] In general, the laser power can be either constant or already fixedly preset as a function of image frequency and angle. The...
