Product dimension measurement method, device, equipment and medium

The invention discloses a product size measurement method, device and equipment and a medium, and relates to the technical field of three-dimensional measurement. The method comprises the following steps: shooting a to-be-detected product through a preset top camera and a preset bottom camera to obtain the upper surface and the lower surface of the to-be-detected product, and determining the inclination angle of the upper surface and the inclination angle of the lower surface of the to-be-detected product according to the upper surface and the lower surface of the to-be-detected product; determining an inclination angle of the to-be-measured product based on the upper surface inclination angle and the lower surface inclination angle of the to-be-measured product and a calibration block upper surface inclination angle and a calibration block lower surface inclination angle of a preset calibration block; performing rotation adjustment on the upper surface and the lower surface of the to-be-measured product acco
