(EN) A method for expanding a dynamic range of a light detection and ranging (LiDAR) system is provided. The method comprises transmitting, using a light source of the LiDAR system, a sequence of pulse signals consisting of two or more increasingly stronger pulse signals. The method further comprises receiving, using a light detector of the LiDAR system, one or more returned pulse signals correspondingto the transmitted sequence of pulse signals. The one or more returned pulse signals are above the noise level of the light detector. The method further comprises selecting a returned pulse signal within the dynamic range of the light detector, identifying a transmitted pulse signal of the transmitted sequence that corresponds to the selected returned pulse signal, and calculating a distance based on the selected returned signal and the identified transmitted signal.
(ZH) 提供了一种用于扩展光检测和测距(LiDAR)系统的动态范围的方法。所述方法包括通过使用LiDAR系统的光源来发射脉冲信号的序列,所述脉冲信号的序列包括两个或更多愈发更强的脉冲信号。所述方法此外包括通过使用LiDAR系统的光检测器来接收与所发射的脉冲信号的序列相对应的一个或多个所返回的脉冲信号。所述一个或多个所返回的脉冲信号在光检测器的噪声水平以上。所述方法此外包括选择在光检测器的动态范围内的所返回的脉冲信号,标识与所选择的所返回的脉冲信号相对应的所发射的序列中的所发射的脉冲信号,以及基于所选择的所返回信号以及所标识的所发射信号来计算距离。
