The invention discloses a video caption positioning method, electronic equipment and a computer storage medium. The video caption positioning method comprises the following steps: acquiring all imageframes of a video, and performing text detection on all the image frames to obtain a first textbox set of all the image frames, the first textbox set comprising a textbox of each image frame; traversing the first textbox set, and obtaining first similarity of textboxes in every two image frames in a first direction; constructing a first graph network about the first textbox set based on the plurality of first similarities; and clustering the first graph network to obtain a plurality of first sub-networks, and extracting a textbox of the video caption from the first sub-networks of which the node number meets a first preset condition. Through the video caption positioning method, the video caption positioning accuracy can be improved, and other interference information in the video is effectively eliminated.
