What is a common issue when using lidar in outdoor environments?

Sensitivity to ambient light conditions is a well-known challenge when using lidar in outdoor environments. Lidar systems operate by emitting laser pulses and measuring the time it takes for the light to bounce back after hitting a surface. In bright sunlight, intense ambient light can interfere with the lidar signal, reducing the system's effectiveness in accurately detecting objects or surfaces. This can lead to unreliable data, particularly in environments where reflective surfaces or direct sunlight are prominent.

The other choices address different concerns that may be relevant in specific contexts, but they do not directly align with the widespread issues encountered with lidar technology outdoors. For instance, while there can be interference from radar in certain advanced applications, it is not commonly a problem for lidar systems. Low resolution of captured images is more of a characteristic of the specific lidar system in use rather than a universal issue in outdoor environments. Lastly, the inability to detect moving objects does not accurately reflect lidar's capabilities; in fact, many lidar systems are specifically designed to track moving objects effectively. Therefore, sensitivity to ambient light remains the most pertinent challenge associated with lidar use outdoors.
