Abstract
The invention discloses a kind of camera focus adjusting methods of view-based access control model detection and system, this method to comprise the step of：S10：Image picture is continuously acquired by camera and is generated in systems；S20：Camera heights are automatically adjusted in systems；S30：The image that different parameters obtain is compared, determine most sharp image and preserves parameter value, the focus adjusting system, which includes：Image continuous acquisition module, the module are for implementing to obtain image picture；Parameter adjustment module, the module user change parameter output signal control motor and change camera heights；Scheme preserving module, the module carry out home operation after system start-up, and then controlling camera according to scheme is moved to corresponding height, compared with prior art, the beneficial effects of the invention are as follows：The present invention can automatically adjust focal length according to different product, and the height between camera and product is measured without hand-operated lifting, convenient succinct, meet the needs of quickly focusing after replacement of products.
Description
Technical field
The present invention relates to technical field of vision detection, specially a kind of camera focus adjusting method of view-based access control model detection with
And system.
Background technology
Currently, Machine Vision Inspecting System is quickly grown, domestic application enterprise gradually increases, but many enterprises are not because have
There are the personnel of profession to promote application, cause application level generally not high, especially relates to some complicated operations, such as phase
The adjusting of machine focal length and the whether accurate problem of focal length, are related to the precision of measurement, especially with common focusing lens,
In the case of detected product length, width, height any variation, professional is required for use calibration measurement tool repeatedly
Calibration can be only achieved the desired precision of detection, and cost required in this way will improve, and the in addition sequence of traditional software list is
It is postponed by its own product and its before thering is the software of investment relation to set and by rival's product；The businessman of promotion expense will have been given
Product set before, secondly just consider the factors such as scoring, issuing time, download of software, cause when thinking that user recommends software,
The software matrix for being presented to user is essentially identical, machinery and without individual difference, cannot meet the needs of different user.
Invention content
The problem of for background technology, the present invention provides a kind of camera focus adjusting sides of view-based access control model detection
Method and system.
To achieve the above object, the present invention provides the following technical solutions：A kind of camera focus adjusting of view-based access control model detection
Method includes the following steps：
S10：Image picture is continuously acquired by camera and is generated in systems；
S20：Camera heights are automatically adjusted in systems；
S30：The image that different parameters obtain is compared, determine most sharp image and preserves parameter value.
As a kind of preferred technical solution of the present invention, the specific steps that camera heights are adjusted in the S20 include：
a：Current image is observed according to camera continuous acquisition；
b：The rise and fall that camera is realized in motor rotation are controlled according to regulating system parameter；
c：Corresponding image is obtained according to different parameters；
d：It determines most sharp image and preserves parameter value.
The camera focus adjusting method detected according to a kind of view-based access control model set forth above, it is also proposed that be suitable for one kind
The camera focus regulating system of this method, the system include：
Image continuous acquisition module, the module are for implementing to obtain image picture；
Parameter adjustment module, the module user change parameter output signal control motor and change camera heights；

b：The rise and fall that camera is realized in motor rotation are controlled according to regulating system parameter；
c：Corresponding image is obtained according to different parameters；
d：It determines most sharp image and preserves parameter value.
A kind of system of focus adjustment, the system include：
Image continuous acquisition module 100, the module are for implementing to obtain image picture；
Parameter adjustment module 200, the module user change parameter output signal control motor and change camera heights；
Scheme preserving module 300, the module carry out home operation after system start-up, and then controlling camera according to scheme moves
Move corresponding height.
By the method and system adjusted for camera focus set forth above, can be automatically adjusted according to different product burnt
Away from, the height between camera and product is measured without hand-operated lifting, it is convenient succinct, meet and quickly focuses after replacement of products
Demand, can more accurately carry out focus adjustment while can cost-effective raising working efficiency.
