Abstract

The invention relates to the technical field of dimension measurement, in particular to a workpiece dimension measurement method and device. The measurement method comprises the following steps: acquiring an image of a to-be-measured workpiece, calibrating pixels of the image, and performing matching measurement on the image by combining the calibrated pixels with a preset comparison standard so as to acquire the size of the to-be-measured workpiece. Because the calibrated pixel has a small size, the measurement of the size of a workpiece with a small volume can be realized through the pixel calibrated in advance. Meanwhile, the shape and the size of the workpiece do not need to be considered during measurement, the size of the workpiece can be obtained through the calibrated pixels as long as the workpiece is in the shooting range, and high practicability and anti-interference performance are achieved. According to the workpiece dimension measurement method provided by the embodiment of the invention, the dimension measurement of the workpiece can be realized more quickly and accurately, the measurement error of the workpiece dimension is reduced, the measurement efficiency is improved, and the method has relatively high practicability and popularization value.

Description

【Technical field】 [0001] The invention relates to the technical field of size measurement, in particular to a method and device for measuring the size of a workpiece. 【Background technique】 [0002] With the development of society, the requirements for product quality are getting higher and higher, and the installation accuracy of parts on the product often determines the quality of the product. Before assembling the parts, it is often necessary to measure the dimensions of the parts to ensure that the parts installed on the product are up to standard. At present, the common measurement method is to use measuring tools such as tape measure to measure parts. When the volume of parts is small, this measurement method often cannot achieve high measurement accuracy, which leads to the measurement of small parts. Accurate measurement results cannot be obtained when taking measurements. 【Content of invention】 [0003] In order to solve the problem of low measurement accuracy w...
