Jak obliczyć zasięg czujnika i rozdzielczość dla systemów Lidar w robotach mobilnych
Table of Contents
To jest bardzo ważne, aby móc zrozumieć, że te wszystkie systemy Lidar są bardzo skuteczne i nie mogą być wykorzystywane do celów innych niż te, które są w stanie osiągnąć.
Sensor Range Calculation
Te sensor range refers to thee maximum distance at which thee Lidar can detect objects. It depends on factors such as laser power, receiver sensitivity, and environmental conditions. To estimate thee effective range, consider the signals -to- noise ratio and thee reflectivity of target surfaces.
Matematyka, że range can by zbliżone using thee LiDAR equation:

Resolution Calculation
Resolution determinates the smalest differentishable detail in thee environment. It is influenced by the angular resolution and thee scanning frequency of thee Lidar. Highder resolution allows for more detailed ed mapping but may reduce the maximum range.
Te angular resolution is typically specified in degrees. To find thee spational resolution at a certain distance, use:
Resolution = 2 * Distance * tan (Angular Resolution / 2) Resolution / 2) Resolution 1; Resolution 1; FLT: 1 Resolution 3; Employ3; FLT: 1 Resolution: 1 Resolution 3; Employment 3;
Praktyczne rozważania
When selecting a Lidar system, consider the operational environment. Factors such as ambient light, weathers conditions, and target surface performances can affect both range and resolution. Testing in real- eterd contrios helps determinae optimal sensor specifications.
