Monitoring system, monitoring device, monitoring method

A monitoring device for controlling and operating a LiDAR scanner, the monitoring device comprising

• at least one memory storing computer-executable instructions;
• and
• at least one processor configured to access the at least one memory and execute the computer-executable instructions to:
• control a fixed-point three-dimensional LiDAR scanner in such a way that the fixed-point three-dimensional LiDAR scanner performs scanning in a first scanning range for scanning at least a monitoring target and generating a first point cloud, the scanning in the first scanning range being performed at a first scanning density;
• align the first point cloud and known three-dimensional shape data about the monitoring target with each other;
• determine a second scanning range for scanning at least the monitoring target, the second scanning range being narrower than the first scanning range, based on a result of the alignment;
• and
• control the fixed-point three-dimensional LiDAR scanner in such a way that the fixed-point three-dimensional LiDAR scanner performs scanning in the second scanning range that is narrower than the first canning range and generating a second point cloud, the scanning in the second scanning range being performed at a second scanning density that is higher than the first scanning density.

A computer-implemented monitoring method performed by a computer for controlling and operating a LiDAR scanner, the monitoring method comprising:

• controlling a fixed-point three-dimensional LiDAR scanner in such a way that the fixed-point three-dimensional LiDAR scanner performs scanning in a first scanning range for scanning at least a monitoring target and generating a first point cloud the scanning in the first scanning range being performed at a first scanning density;
• aligning the first point cloud and known three-dimensional shape data about the monitoring target with each other;
• determining a second scanning range for scanning at least the monitoring target, the second scanning range being narrower than the first scanning range, based on a result of the alignment;
• and
• controlling the fixed-point three-dimensional LiDAR scanner in such a way that the fixed-point three-dimensional LiDAR scanner performs scanning in the second scanning range that is narrower than the first canning range and generating a second point cloud, the scanning in the second scanning range being performed at a second scanning density that is higher than the first scanning density.
