The invention discloses a cloud-based residential corridor lighting system which includes a cloud server, a lighting module, an image acquisition module, an image processing module and a local end host. The lighting module and the image processing module are connected to the local end host. The image acquisition module is connected to the image processing module. The local end host is connected tothe cloud server. The lighting module is used to provide an illumination light source, and the image acquisition module is used to collect a portrait and send the captured portrait image informationto the image processing module. The image processing module is used to extract received human flow information data and send the received human flow information data to the local end host. The local end host is used to store the received human flow information data and send the received human flow information data to the cloud server, and the cloud server is used to receive and store the human flow information data sent by the local end host and establish a training model, the training model is updated through periodic training, and the training model updated each time is sent to the local endhost.
