The invention discloses an event camera denoising method and system, network equipment and a storage medium, and belongs to the technical field of image processing. The method comprises: acquiring an original event stream; secondly, reducing the dimension of an event point in the event stream to a one-dimensional time domain, and if the timestamp of the event point is isolated in the time domain, taking the event point as a noise event to be removed; thirdly, performing dimensionality reduction on the event points in the event stream to a two-dimensional space domain, and if the grouping degree of the event points in the two-dimensional space is smaller than the mean value of the grouping degrees of all the event points, regarding the event points as noise events and removing the noise events. Based on the difference between the noise of the event camera and the target, the noise of the event camera is filtered under the constraints of the time domain and the space domain, and the imaging quality of the event
