Correction method, device and computer program product for lidar data

The invention discloses a correction method and device for laser radar data. The method comprises the following steps: recording a plurality of signal characterization values when a real-time signal intensity value of an echo signal respectively reaches a plurality of target signal intensity values; and obtaining a data correction relationship between the signal intensity value and the signal characterization value of the echo signal based on the plurality of target signal intensity values and the plurality of signal characterization values. Compared with the prior art, the scheme of the invention has the advantages of simple data correction process, high accuracy of corrected data and the like. 本发明公开了一种用于激光雷达数据的修正方法和设备，其中所述方法包括：记录回波信号的实时信号强度值分别达到多个目标信号强度值时的多个信号表征值；以及基于多个目标信号强度值和多个信号表征值来获得所述回波信号的信号强度值与信号表征值的数据修正关系。相对于现有技术，本发明的方案具有数据修正过程简单和修正数据精确度高等优势。
