An intelligent forklift and a method for detecting a pose deviation of a container are provided. The intelligent forklift includes a working state monitor, an image sensor, and a processor. The working state monitor is configured to monitor a working state of the intelligent forklift while the intelligent forklift is carrying and moving a stock container and send a trigger to the image sensor based on the working state. The image sensor is configured to capture an RGBD image frame containing the stock container in response to the trigger and to transmit the RGBD image frame to the processor. The processor is configured to receive the RGBD image frame, detect a pose deviation degree of the stock container and provide an alarm and/or a prompt based on a detection result of the pose deviation degree for adjusting the pose of the stock container.
