Cigarette online scanning and detection system

The invention provides a cigarette online scanning and detection system. The cigarette online scanning and detecting system comprises a cigarette production line which includes a conveying line for conveying cigarette packets, an online scanning and detection device, a controller and a sorting mechanism, wherein the online scanning and detection device includes a detector assembly and a ray sourceassembly, a detector in the detector assembly and a photon ray source in the ray source assembly are oppositely arranged; the conveying line penetrates through the detector and the photon ray source,a first included angle is formed between the direction of detection light emitted by the photon ray source and the conveying direction of the conveying line, the detection light forms a diagonal plane forming a second included angle with a cross section of the cigarette packet on the cigarette packet, and the detector acquires the detection light to form an image for separating cigarettes in thecigarette packet; the contr
