Description
Technical field
The utility model relates to a kind of measuring devices, more particularly, to a kind of image measuring apparatus of cable section.
Background technique
Cable industry is the second largest industry in machinery industry, the derived units base such as its density, pressure in scientific research field
Standard has standard-sized requirement, and the outer diameter of cable directly affects the performance of cable.Such as wire and cable core outer diameter and led
Bulk resistor is related, seriously affects electric conductivity, restricts product quality, so the product structure ruler of strict control wire and cable
It is very little, it is an important link for guaranteeing wire and cable performance and quality level.Wherein cable in plastics cable extrudes the outer of product
Diameter directly affects the insulation effect of product, pressure-resistant degree, so must survey to the outer diameter of insulated wire cores and extrude sheath
Amount checks.
As long as the prior art passes through the 1) direct method of measurement: directly reading cable dimension outer diameter using vernier caliper, repeatedly
Averaged is measured, but the deep informations such as cable insulation, protective layer can not be obtained；2) direct-reading method is projected: by using throwing
Shadow instrument or reading microscope and laser diameter measurement product profile directly measure, and obtain the deep information of product.Both methods
Mainly by manual measurement, it often will appear time-consuming, and measurement accuracy is not accurate enough and can only measure asking for a certain privileged site
Topic, is unable to the multi-scale information of the Overall Acquisition construction of cable.
Utility model content
The purpose of this utility model is exactly to provide a kind of cable section to overcome the problems of the above-mentioned prior art
Image measuring apparatus.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of image measuring apparatus of cable section, which is characterized in that the measuring device includes:
Cabinet；
Controller is located on cabinet；
Source of parallel light is located in the box body；
Lens bracket is located in the box body；
CCD industrial camera is located on lens bracket, and connect with controller, for shooting cable section to be measured；
Objective table is located in the box body and is located at CCD industrial camera lens direction, for placing cable section to be measured；
Light-shielding sheet is located above objective table；
Spuious optical filter is located above light-shielding sheet.
Preferably, the controller includes micromainframe and display interconnected, the micromainframe and CCD
Industrial camera connection.
Preferably, there are three the CCD industrial camera is set, the lens bracket it is corresponding also only there are three, each CCD
Industrial camera corresponds to a lens bracket.
Preferably, three cameras are three cameras with different focal length.
Preferably, three rectangular regions of different sizes, each CCD industrial camera are dug out inside the light-shielding sheet
It is directed at specific one region.
Preferably, the intracorporal measured zone of the case is divided into three parts, the CCD industrial camera alignment of different height
Different regions.
Compared with prior art, the utility model has the advantage that
One, measurement is accurate, using CCD industrial camera and source of parallel light, constructs jamproof accurately image system；
Two, measured zone is divided into three parts by convenient test, and the CCD industrial camera of different height is directed at different areas
Domain measures, and is successively suitable for middle workpiece, big workpiece and small workpiece from left to right, and it is numerous to avoid single camera bring measurement
The problems such as trivial.
Detailed description of the invention
Fig. 1 is the inside positive structure schematic of the utility model；
In Fig. 1 shown in label:
1, display, 2, micromainframe, 3, cabinet, 4, lens bracket, 5, objective table, 6, source of parallel light, 7, light-shielding sheet, 8,
Spuious optical filter, 9, measured zone, 10, CCD industrial camera.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is a part of the embodiment of the utility model, rather than is all implemented
Example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained all should belong to the range of the utility model protection.
Embodiment:
The utility model designs a kind of image measuring apparatus of cable section, and this device is mainly surveyed according to the cross-section of cable
The geometric dimensions such as the average thickness of insulating layer, shielded layer, restrictive coating etc., minimum thickness, maximum gauge are measured, make measurement result more
Accurately and reliably.
The image measuring apparatus of the utility model cable section, including be located at the display 1 of top of the box, micromainframe 2,
Cabinet 3, the objective table 5 positioned at the bottom of box, source of parallel light 6, is located above objective table the lens bracket 4 for being located in the box body portion
Light-shielding sheet 7, the spuious optical filter 8 above light-shielding sheet, the measured zone on spuious optical filter 9, three be located at mirror
CCD industrial camera 10 on head bracket.Since the focal length of industrial camera lens is an important index, when to same distance
When the same target subject is shot, lens focus is longer, and field range is narrower, and area of each element in picture is got over
Greatly, and lens focus is shorter, and field range is wider, and area of each element in picture is with regard to smaller.According to this principle, will survey
Amount region is divided into three parts, and the CCD industrial camera of different height is directed at different regions and measures, successively fits from left to right
It for middle workpiece, big workpiece and small workpiece, can not thus be influenced by workpiece actual size, to obtain the electricity for being suitble to measurement
Cable tangent plane picture.Common PC can be used in micromainframe therein, and Dell optiplex 7060mff can be used in PC.
This product constructs anti-tampering accurately image system by multiple CCD industrial cameras and source of parallel light.By existing
Full scan and sub-pixel interpolation calculate and obtain measurement point, carry out camera calibration by standard ring and solve distortion model, and benefit
The average thickness, minimum thickness, maximum gauge etc. of measured workpiece are obtained with the mode of GVF and Chebyshev polynomial interopolation
Geometric dimension, the statistical method taken multiple measurements eliminate accidental error, realize reliable measurement.And by existing
Radon transformation, makes system can be carried out image analysis and signal reconstruction in the environment in noise source, improves this product to making an uproar
The adaptability of acoustic environment, to realize the automatic identification of cross section type and generate measurement report.
