Three-dimensional measurement method and device, electronic equipment and storage medium

The invention provides a three-dimensional measurement method and device, electronic equipment and a storage medium. The three-dimensional measurement method comprises the following steps: firstly, acquiring a composite image sequence of an object to be measured; and then based on the composite image sequence, calculating to obtain an average intensity graph, a modulation intensity graph and a wrapped phase graph of the to-be-measured object. Based on the average intensity diagram and the modulation intensity diagram, a contrast diagram of the to-be-measured object is obtained through calculation, and based on the phase diagram, a phase difference diagram of the to-be-measured object is obtained through calculation. And then, based on the contrast graph and the phase difference graph, extracting to obtain a Gray code pattern. And based on the Gray code pattern, calculating to obtain an initial stripe order. And calculating an absolute stripe order based on a preset virtual stripe order and the initial stripe
