The invention discloses a converse non-contact measuring method for complicated miniature members, including: 1. the complicated miniature members which need to be measured are coated with developing agents and then are processed by the operation of drying; 2. the complicated miniature members processed by the operation of drying are arranged on a table body of the measuring device, the table bodyis coated with a non-glare black coating layer, and the complicated miniature members and a measuring device form a whole body; and the three-dimensional data of the whole body are measured by a measuring machine and then are stored in a computer, and finally the measured three-dimensional data of the complicated miniature members can be obtained after the three-dimensional data of the measuringdevice are deleted from the computer. The method has the characteristics of comprehensive and accurate measure data and convenient execution, and the method can be matched with the measuring device tomeasure the three-dimensional data of the complicated miniature members from various visual angles, thereby solving the problem of hard full angle measurement of the complicated miniature members dueto the undersize thereof. The measuring device of the invention has the advantages of simple structure, low cost, easy realization and convenient popularization and application.
