Method and Device for Operating a Plurality of Lidar Sensors

A device for operating a first lidar sensor and a second lidar sensor, which are each configured, within a measurement period, to sequentially acquire a frame of measured values for a plurality of different measurement points in a common acquisition area of the first lidar sensor and the second lidar sensor;

• wherein the device is configured:
• to operate the first lidar sensor using a first scanning pattern to scan the plurality of measurement points, in order to acquire a first frame of first measured values for the plurality of different measurement points in the measurement period;
• to operate the second lidar sensor using a second scamming pattern to scan the plurality of measurement points, in order to acquire a second frame of second measured values for the plurality of different measurement points in the measurement period;
• wherein:
• the first scanning pattern and the second scanning pattern each have different scanning directions for scanning the plurality of measurement points;
• and/or
• the plurality of measurement points in the second scanning pattern is scanned offset in time in relation to the first scanning pattern;
• and
• to ascertain an overall frame of measured values in the measurement period based on the first frame and based on the second frame.

A device for operating a lidar sensor, which is configured, within a measurement period, to sequentially acquire a frame of measured values for a plurality of different measurement points in an acquisition area of the lidar sensor;

• wherein the device is configured:
• to determine a scanning pattern having a pseudorandom sequence of the plurality of measurement points by way of a random generator;
• and
• to operate the lidar sensor in the measurement period using the ascertained scanning pattern to scan the plurality of measurement points, in order to acquire a frame of measured values for the plurality of different measurement points in the measurement period.
