The invention discloses a binocular structured light three-dimensional imaging method and system based on an event camera, relates to the field of binocular structured light three-dimensional imaging, solves the problems that a CCD camera used in an existing binocular structured light three-dimensional imaging method is low in response speed, large in energy consumption and prone to generating large errors, and provides the following scheme. The method comprises the following steps that S1, a control module, a light structure projection device and an image acquisition device are arranged, and the image acquisition device adopts an event camera; s2, image acquisition: establishing a coordinate system, acquiring by two cameras, and having different position relations; s3, calibrating a camera; s4, calculating the distance between the space point P and the camera according to the parallax and the internal reference of the camera; and S5, determining the depth. According to the method, the event camera is used fo
