Abstract
The present invention relates to a size detection method for an automobile door. The method comprises the steps of determining an upper coordinate, a lower coordinate, a left coordinate and a right coordinate on an automobile door, scanning the size of the automobile door through aligning with the above four coordinates by means of an industrial camera, and transmitting to a computer. The standard size of a to-be-detected automobile door is preset in the computer, and the precision of detection parameters is set on request. Through detecting an introduction computer, the treatment is conducted based on VC + + image processing techniques. The result of the Hough transform detection is directly applied to the collected automobile door and then a result output part outputs detection data. Through comparing the data with standard size data input into the computer, the automobile door with the detection parameters thereof within the precision range of detection parameters is determined to be a qualified product according to the preset precision of detection parameters. If the detection parameters of the automobile door are out of the precision range of detection parameters, the automobile door is determined to be a defective product. After that, the defective automobile door is reminded by the computer of being processed. Therefore, the detection efficiency is greatly improved, and the consumption of manpower and material resources is reduced. The production quality is improved.
Description
Technical field
The invention belongs to technical field of automobile detection, more particularly to a kind of arrangements for automotive doors size detecting method.
Background technology
The rapid growth of China's economic, makes living standards of the people have started to march toward well-to-do level.Work as household electrical appliance
After fully popularizing, the emphasis of consumption of resident will turn to the house and automobile of wholesale.Exactly in this consumption
Under trend, automobile industry maintains at a relatively high growth rate.And this propensity to consume, affirmative will also be in the present
Accelerate within several years afterwards to continue, this has established extraordinary basis for the development of automobile industry.Auto manufacturing
Certainly can develop accordingly, auto parts machinery processing constitutes the overall each unit of auto parts machinery processing and serves vapour
The product of car accessory processing, with being growing more intense that auto parts machinery processing market is competed, parts industry
All multiple enterprises progressively separate from vehicle complete vehicle manufacturer, define independent, complete business organization,
And present tissue grouping of the world economy, technology high zinc foods, Cargo Delivery System and manage the new features such as globalization.Wherein
The production of car door is particularly important, is currently the method for relying primarily on manual measurement for the size detection of car door,
Manual measurement precision is low, and quality of production qualification rate is low, low production efficiency.
The content of the invention
The technical problem to be solved in the present invention is, for the deficiencies in the prior art, to propose a kind of arrangements for automotive doors size
Detection method.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of arrangements for automotive doors size
Detection method, comprises the following steps：
(1) four, upper and lower, left and right coordinate, is determined on car door, four seats is directed at by industrial camera
Mark carries out vehicle body door size scanning, is transmitted to computer；
(2), arrangements for automotive doors standard size to be detected is set in a computer, detection parameter is set as requested
Precision；By detecting that incoming computer is processed with VC++ image processing techniques；
(3), the arrangements for automotive doors to collecting directly uses Hough transform testing result；
(4), result output par, c output detection data, is compared by the object staff cun with being input into computer, according to
The detection parameter precision of setting, within detection parameter accuracy rating for qualified products, in detection parameter essence
Outside degree scope for substandard products, substandard products process is carried out by computer prompted.
Compared with prior art, the present invention increases substantially detection by using COMPUTER DETECTION car door size
Efficiency and reduction manpower and materials consumption, improve the quality of production.
Specific embodiment
The concrete technical scheme of the present invention described further below, it is further in order to those skilled in the art
Ground understands the present invention, and does not constitute the restriction of its power.
Embodiment 1, a kind of arrangements for automotive doors size detecting method, comprise the following steps：
(1) four, upper and lower, left and right coordinate, is determined on car door, four seats is directed at by industrial camera
Mark carries out vehicle body door size scanning, is transmitted to computer；
(2), arrangements for automotive doors standard size to be detected is set in a computer, detection parameter is set as requested
Precision；By detecting that incoming computer is processed with VC++ image processing techniques；
(3), the arrangements for automotive doors to collecting directly uses Hough transform testing result；
(4), result output par, c output detection data, is compared by the object staff cun with being input into computer, according to
The detection parameter precision of setting, within detection parameter accuracy rating for qualified products, in detection parameter essence
Outside degree scope for substandard products, substandard products process is carried out by computer prompted.
Compared with prior art, the present invention increases substantially detection by using COMPUTER DETECTION car door size
Efficiency and reduction manpower and materials consumption, improve the quality of production.
