The embodiment of the invention provides a badminton serving height violation detection method and device, and the method comprises the steps: firstly obtaining a to-be-detected video collected by a camera at a standard serving height, solving a visual horizontal line in the to-be-detected video through employing a vanishing line detection algorithm, and enabling the visual horizontal line to be a reference line corresponding to the standard serving height in the to-be-detected video; and then, inputting the to-be-detected video into a preset serving state detection model for feature extraction and prediction to obtain the probability that the to-be-detected video is in the serving state, and comparing the probability with a preset threshold value to judge whether the to-be-detected video is in the serving state or not. And when the to-be-detected video is in the serving state, determining the position of the shuttlecock by using a preset target detection model. And finally, comparing the position of the badm
