The invention relates to a three-dimensional measurement out-of-tolerance range automatic marking method, system, equipment and medium, and the method comprises the steps: firstly obtaining three-dimensional scanning data of a target workpiece based on scanning equipment, then comparing the three-dimensional scanning data with a preset digital model of the target workpiece based on a preset out-of-tolerance threshold value to obtain out-of-tolerance boundary data, and then obtaining a coordinate conversion model; and according to the out-of-tolerance boundary data, an instruction is sent to a marking device to mark the target workpiece. Compared with the prior art, the out-of-tolerance boundary data on the workpiece is obtained by analyzing the three-dimensional scanning data, and the out-of-tolerance boundary data can be used as a reference for the operation of the marking equipment by using the coordinate conversion model, so that the out-of-tolerance position is automatically marked by using the marking eq
