This invention discloses a method, apparatus, device, and medium for tracing filter rod quality anomalies. The method includes: acquiring images of the end faces of multiple first filter rod sets entering a filter rod library at preset time intervals; determining corresponding first filter rod set information based on the acquired images of each first filter rod set, wherein the first filter rod set information includes at least the identifier of the molding machine that produced the first filter rod set, the quality parameters of the first filter rod set, and the time of image acquisition; establishing logical units with the molding machine's startup to shutdown period as a time window; for each logical unit, aggregating the first filter rod set information corresponding to all first filter rod sets processed in the target area of ​​the filter rod library within the corresponding time window of the logical unit, as well as the time window itself, into the logical unit, to perform filter rod quality anomaly tracing according to the logical unit; wherein, the target area of ​​the filter rod library is the remaining filter rod processing area in the filter rod library excluding the buffer zone. This invention enables efficient and accurate tracing of filter rod quality anomalies.
