The invention discloses a three-dimensional dimension measurement method and device and relates to the technical field of measurement. The method comprises the following steps: obtaining three-dimensional point cloud data of a target measurement object, and determining distance between a point position corresponding to each point cloud data in the three-dimensional point cloud data and a shooting object as well as the distance between two adjacent point positions; deleting the point cloud data corresponding to the point position, wherein the distance between point position and the shooting object is larger than a first threshold value and the distance between the two adjacent point positions is larger than a second threshold value, to obtain first three-dimensional point cloud data; carrying out SLAM algorithm on the three-dimensional point cloud data to determine the distance between the shooting object and a reference plane and the included angle between the shooting object and the reference plane; mapping the first three-dimensional point cloud data to a coordinate system of the shooting object; and establishing a three-dimensional model of the three-dimensional point cloud data according to the first three-dimensional point cloud data mapped to the coordinate system, and determining the three-dimensional dimension and size of the target measurement object according to the three-dimensional model.
Description
technical field [0001] The present invention relates to the technical field of measurement, and in particular to a method and device for measuring three-dimensional dimensions. Background technique [0002] The automatic and accurate collection of logistics attributes such as three-dimensional size, volume, weight, and barcode of goods will help logistics companies meet higher and faster logistics needs. At present, in domestic logistics enterprises, the collection and development of product weight and barcode information is relatively mature. Using weighing equipment such as electronic scales to weigh and barcode reading with scanning guns can achieve good results, but it is necessary to measure the three-dimensional size of the product. Occasionally, it is generally measured manually with tools such as a tape measure. In the traditional way, the three-dimensional size measurement of the product, the tools are backward, the efficiency is low, the labor cost is high, the er...
