Abstract
The invention relates to the technical field of detection on industrial production lines and in particular relates to a beverage can defect detection system and method based on spatial expansion. The system comprises a product transfer line, and an intelligent camera and a light source which are erected above the product transfer line, wherein the intelligent camera is sequentially connected with a three-dimensional modeling and detection comparison computer and a PLC; and a front cambered surface prism group and a rear cambered surface prism group are arranged on the product transfer line and form a cambered surface prism combination. According to the system and the method disclosed by the invention, only a single camera is needed, the cost of the system is reduced, an image splicing algorithm with the large operation amount is not used, the program running speed is reduced, and the requirement on a processor is small.
Description
Technical field
The present invention relates to industrial production line detection technique field.Be specifically related to the beverage can defect detecting system based on spatial spread and detection method.
Background technology
In the packaging of beverage can is produced, for preventing substandard product from coming into the market, beverage can manufacturer many employings manual detection mode detects to cancel substandard product.And the external packing production line of One's name is legion is difficult to the requirement being met its speed and stability under manual detection.Beverage can line speed can to 200 per minute.And pattern updating decision, of a great variety, easily there is fatigue thus bring detection mistake in manual detection.
The defect detecting system of existing a kind of vision based on polyphaser.Its ultimate principle uses multiple smart camera to take regions all around beverage can, carries out image mosaic with the different angles image obtained.By spliced whole tank body plane picture, it is analyzed, verifies the matching degree of its pattern.This defective system needs smart camera, light source, controller PLC and computing machine.Its physical arrangement is shown in Fig. 1.Wherein smart camera needs 4+1.Although solve the problem of manual detection but also exist: 1) smart camera demand is many, and equipment cost budget is excessive; 2) different cameral has been taken pictures error, can not complete picture splicing, affect testing result; 3) picture stitching algorithm exists measuring error affects testing result; 4) picture stitching algorithm is longer for operation time, high to hardware requirement.
Summary of the invention
The object of the invention is to overcome in prior art the problem that Intelligent Measurement cost is high, error is large, imaging time is long.
For this reason, the invention provides a kind of capture mechanism based on spatial spread, comprise smart camera, also comprise the left and right globoidal prism group being arranged on the left and right sides, district to be detected, absorb for described smart camera for the picture obtaining detected material side face;
Described smart camera is vertically set on directly over detected material;
The horizontal sextant angle in described left and right globoidal prism group and district to be detected is 60-80 degree.
Described left and right globoidal prism group is made up of the globoidal prism that at least three arrange in turn.
Described globoidal prism is common plane mirror.
Based on a beverage can defect detecting system for spatial spread, comprise smart camera and the light source of district to be detected and top erection thereof; Smart camera is connected with three-dimensional modeling in turn and detects comparing calculation machine, PLC, the left and right globoidal prism group that the left and right sides in described district to be detected being respectively arranged with picture for obtaining the detected material side face in district to be detected, absorbing for described smart camera, smart camera is vertically set on directly over detected material; The horizontal sextant angle in left and right globoidal prism group and district to be detected is 60-80 degree.
Described light source adopts industrial LED light source.
Described left and right globoidal prism group is made up of the globoidal prism that at least three arrange in turn.
Beneficial effect of the present invention: this beverage can defect detecting system based on spatial spread provided by the invention, comprises smart camera and the light source of product conveyor line and top erection thereof; Smart camera is connected with three-dimensional modeling in turn and detects comparing calculation machine, PLC, and described product conveyor line erection front arc prism group, rear arc prism group, front and back globoidal prism forms globoidal prism combination.The present invention only needs single camera, reduces system cost, does not use the picture stitching algorithm that operand is large, reduces program operation speed, few to processor requirement.
Below with reference to accompanying drawing, the present invention is described in further details.
