Embodiment Construction

[0029] In actual life and production, a test technology and its calculation method and application of the built-in scale of the imaging system mainly involve the measurement of the width of the crack, the thickness of the rock formation, the size of the flying object, etc. Let’s take the measurement of the crack width as an example to explain in detail .

[0030] refer to figure 1 , a testing technique for a built-in scale in an imaging system and its calculation method and application, specifically, it is mainly composed of an imaging system, a light source, a lens and a grating.

[0031] The imaging system is a high-definition camera, preferably one of a mobile phone, a camera, a microscope, and the like.

[0032] The light source includes laser lamps, fluorescent lamps, incandescent lamps, tungsten iodine lamps, etc., preferably laser lamps.

[0033] The grating is preferably a transmission grating.

[0034] The lens is preferably a convex lens.

[0035] For the measure...

Abstract

The invention discloses a test technology based on a built-in scale in an imaging system and a calculation method and an application thereof. The invention mainly aims at the dimension analysis of a micro or macro object in an imaging system. The conception of the invention is completed by three steps: object shooting, image extraction, and dimension calculation. The basic components of the test technology are an imaging system, a light source, a lens, and a grating. A parallel light technology is mainly implemented by the light source and the lens. The grating is used for forming equal-width and equal-distance parallel light. The imaging system converts the equal-width and equal-distance parallel light into a two-dimensional spot array. Compared with the traditional test methods, the remote test technology of the invention is convenient and quick in measurement and high in accuracy of measurement, and has obvious advantages especially for test of micro objects. The test technology can be used in fields such as engineering test, machine manufacturing, and material detection.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a test technology for a built-in scale of an imaging system, a calculation method and an application thereof. Background technique [0002] In daily engineering testing, mechanical manufacturing, material testing, etc., the size of objects and their size changes are usually a crucial factor, such as the width of cracks, the thickness of rock formations, the size of flying objects, etc. Generally speaking, there are two types of measurement methods, contact and non-contact. Traditional measurement methods generally use micrometers or vernier calipers, mainly due to their strong universality, no special requirements on the material and reflection characteristics of the measured object, and they are not affected by body color and curvature. However, as a contact measurement method, the operability of microscopic object measurement is not strong, and there is no zoom...
