Embodiment Construction

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] see figure 1 , the first embodiment of the present invention provides a method for measuring the size of a workpiece, which is used to measure the contour size of the workpiece, which includes the following steps:

[0036] Obtain an image of the workpiece to be tested;

[0037] Calibrate the pixels of the image;

[0038] The image is matched and measured through the calibrated pixels combined with the preset comparison standard to obtain the size of the workpiece to be measured.

[0039] It can be understood that the image of the workpiece to be measured is generally capt...

Abstract

The invention relates to the technical field of size measurement, in particular to a method and device for measuring the size of a workpiece. The measurement method includes the following steps: acquiring an image of the workpiece to be measured, calibrating the pixels of the image, and performing matching measurement on the image by combining the calibrated pixels with a preset comparison standard, so as to obtain the size of the workpiece to be measured. Since the calibrated pixels have a smaller size, the size of a smaller workpiece can be measured through the pre-calibrated pixels. At the same time, there is no need to consider the shape and size of the workpiece when measuring. As long as the workpiece is within the shooting range, the size of the workpiece can be obtained through the calibrated pixels, which has high practicability and anti-interference. The workpiece size measurement method provided by the embodiment of the present invention can realize the size measurement of the workpiece more quickly and accurately, reduce the measurement error of the workpiece size, improve the measurement efficiency, and has 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...
