Problems solved by technology

[0003] Machine vision has a wide range of applications in product measurement. The machine vision measurement devices in the prior art are basically equipped with industrial cameras and support seats for supporting products. The industrial cameras capture images of products, and then transmit, In the analysis process, however, the industrial lens and support base adopt a fixed structure design, resulting in a certain measurement area, which is not suitable for the measurement of products of different sizes

Embodiment 1

[0038] see Figure 1-3 , in the embodiment of the present invention, a measuring device based on machine vision includes a first base 1 and a second base 4, and the upper sides of the first base 1 and the second base 4 are respectively provided with a support base 11 and an industrial camera 9;

[0039] The measuring device based on machine vision also includes a control mechanism for changing the measuring area.

[0040] Further, the regulating mechanism includes a rotating mechanism for driving the support base 11 to rotate and an adjusting mechanism for adjusting the position of the industrial camera 9 .

[0041] Specifically, the rotating mechanism includes a driving assembly and an auxiliary assembly.

[0042] The drive assembly includes a motor 3, a rotating shaft 15 and a single-chip microcomputer 13;

[0043] The rotating shaft 15 is installed at the center of the bottom surface of the support seat 11, and the center of the top wall of the first base 1 is provided wi...

Embodiment 2

[0058] see Figure 4-5 , in the embodiment of the present invention, a measuring device based on machine vision is different from Embodiment 1 in that a slide bar 23 is provided inside the support seat 11, and a splint 22 is slidably connected to the slide bar 23, and the splint 22 is symmetrical set of two;

[0059] The top wall of the support base 11 is provided with a strip-shaped slideway 24 matched with the splint 22, and the top of the splint 22 passes through the strip-shaped slideway 24 and extends to the upper side of the support base 11;

[0060] A spring 21 is provided between the splint 22 and the side wall of the support seat 11, and the spring 21 is sleeved on the slide bar 23; through the cooperation of the spring 21, the splint 22 and the slide bar 23, the The product 12 to be measured avoids displacement of the product 12 to be measured during the measurement process, which affects the measurement result.

[0061] The working principle of the embodiment of t...

Abstract

The invention relates to the technical field of machine vision measurement, in particular to a measuring device based on machine vision, which comprises a first base and a second base. The upper sidesof the first base and the second base are respectively provided with a supporting seat and an industrial camera. The measuring device based on machine vision further comprises a regulation and control mechanism used for changing the measuring area, the regulation and control mechanism comprises a rotating mechanism and an adjusting mechanism, and the rotating mechanism comprises a driving assembly and an auxiliary assembly. According to the measuring device based on machine vision, the operation of a motor is controlled through a single-chip microcomputer, the motor drives a rotating shaft and the supporting seat to rotate, so that the industrial camera can conveniently shoot a product to be measured at different angles; and the industrial camera is driven to move in the vertical direction and the horizontal direction through a first electric telescopic rod and a second electric telescopic rod, the purpose of adjusting the position of the industrial camera is achieved, and therefore the measuring area is changed, and the measuring device based on machine vision is suitable for measuring products of different sizes.

Description

technical field [0001] The invention relates to the technical field of machine vision measurement, in particular to a measurement device based on machine vision. Background technique [0002] Machine vision is a rapidly developing branch of artificial intelligence. Simply put, machine vision is the use of machines instead of human eyes for measurement and judgment. The machine vision system converts the ingested target into an image signal through machine vision products, transmits it to a dedicated image processing system, obtains the shape information of the captured target, and converts it into a digital signal according to the pixel distribution, brightness, color and other information. The image system Various operations are performed on these signals to extract the characteristics of the target. [0003] Machine vision has a wide range of applications in product measurement. The machine vision measurement devices in the prior art are basically equipped with industria...
