Disclosed are a background filtering method and a system based on a roadside solid-state lidar, whereby a spatial dividing method of solid-state lidar based on channel scanning angle is designed, single-channel point cloud is extracted, point cloud of each channel of all background data frames are fused and superimposed, each background space unit and non-background space unit based on channel scanning space are identified based on a given threshold; then real-time data frames are subjected to background difference based on channels to obtain the single-channel road user information data frames; the background filtering is achieved by splicing single-channel road user information data frames into a complete road user information data frame.
