, can be by being tested after measurand generates view data for all-in-one formula IMAQ detector
The view data is collected in object, that is, performs step 330.
, whereas if measurand loading configuration parameter is unsuccessful, then it represents that measurand can not normal work, i.e., it is tested
Object is defective products, and now, all-in-one formula IMAQ detector will generate the judgement for being used for indicating that measurand is defective products
Instruct and feed back to master controller so that measurand is moved to bad by master controller according to the decision instruction control machinery hand
Product region.
Further, configuration parameter corresponding to different measurands is different, thus, in configuration parameter loading procedure
In, will be first by obtaining an at least configuration parameter, and then adaptive by configuration parameter in all-in-one formula IMAQ detector
Bootload measurand carries out the configuration of corresponding configuration parameter.
By being arranged such, configuration parameter adaptive allocation is realized, avoids manually participating in, is advantageous to improve image detection
Efficiency, and then be advantageous to improve the production efficiency of camera module.
Step 330, in measurand loading configuration parameter success, the view data generated in measurand is gathered.
Step 340, image detection is carried out to the view data collected.
More preferably, two-way is divided to transmit the view data collected, wherein view data is transmitted to all-in-one formula all the way
The processor of IMAQ detector configuration, by processor, to this, wherein view data carries out the first specified classification image all the way
Detection.The interface that another way view data is configured by all-in-one formula IMAQ detector is transmitted to host computer, with by upper
Position machine carries out second to the another way view data and specifies classification image detection.
In all-in-one formula IMAQ detector, processor can be ARM core chips, and host computer can be calculated
Machine.
Thus, divide two-way to transmit the view data collected, wherein transmit all the way to processor, another way transmit to
Host computer, and then image detection is performed parallel in all-in-one formula IMAQ detector and host computer, carried with this
High image detection efficiency, be advantageous to improve the production efficiency of camera module.
In addition, if host computer can also be all in all-in-one formula IMAQ detector there occurs failure, image detection

Formula IMAQ detector reads the working condition of host computer in real time, if the working condition of host computer is abnormal operation,
Just the image detection of each function is carried out for view data.
Further, all-in-one formula IMAQ detector and the running environment of image detection application program in host computer
It can be mutually distinguishable, i.e., the image detection application program in all-in-one formula IMAQ detector operates in the first operating system,
And the image detection application program in host computer operates in the second operating system.Wherein, the first operating system is kept and tested pair
As the operating system that the terminal device of installing is run is identical, such as (SuSE) Linux OS etc., the second operating system is then advantageous to
Image detection efficiency is improved, such as suitable for Windows operating system of algorithm etc. needed for a variety of image detections.
Thus, the detection environment in all-in-one formula IMAQ detector and practical service environment height one in measurand
Cause, fully ensured that the confidence level of image detection in all-in-one formula IMAQ detector.Meanwhile the detection environment in host computer
Algorithm needed for a variety of image detections is more suitable for, and then make it that image detection is more efficient.
Further, image detection includes but is not limited to：Definition detection, flaw defects detection, bad point detection, focusing
Detection, demosaicing processing, noise reduction process, compensating bad point processing, white balance processing, exposure gain processing, image sharpening processing
Etc..
It should be appreciated that for algorithm needed for above-mentioned image detection, some algorithm computation complexities are higher, such as flaw
Defects detection, some algorithms have different operational efficiency on different operating system, or, produced for camera module
For business, some algorithm secrecies require higher.
Therefore, all-in-one formula IMAQ detector, which provides first, specifies classification image detection, host computer provides second and referred to
Determine classification image detection.Wherein, specify the sorting technique of classification image detection to be based on computation complexity, fortune can also be based on
Line efficiency, or, based on the demand of camera module manufacturer, the degree of accuracy and the efficiency of image detection, Jin Eryou are improved with this
The probability of defective products is mistaken for beneficial to reduction measurand.
For example, the image detection application program in processor operates in (SuSE) Linux OS, the image in host computer
Detection application program operates in Windows operating system, and correspondingly, algorithm needed for the first specified classification image detection can be meter
It is relatively low to calculate complexity, and there is higher operational efficiency in (SuSE) Linux OS, second specifies calculation needed for classification image detection
Method can be that computation complexity is higher, and have higher operational efficiency in Windows operating system, thus further carry
Image detection efficiency has been risen, has improved the production efficiency of camera module.
Or second specify algorithm secrecy needed for classification image detection to require higher, now, the image in host computer
Detection application program can be provided by camera module manufacturer, and classification image detection is specified to carry out second to view data, by
This, for camera module manufacturer, the second class carried out in host computer specifies classification image detection to depend entirely on shooting
The demand of head mould group manufacturer, the security of image detection has fully been ensured with this, is more beneficial for lifting camera module factory

Change the communication Protocol Conversion that firmware specifies measurand and be integrated the communication protocol that machine formula IMAQ detector is specified, so that
Communication connection is successfully established.
It should be appreciated that the camera module that different camera module manufacturers is provided is often off-gauge using some
Interface type, and then cause the communication protocol specified by the interface type to be not quite similar, for example, sub-LVDS interfaces are one non-
Standard interface type.
Therefore, in order to improve the compatibility for the interface connecting plate that all-in-one formula IMAQ detector is provided, it would be desirable to
Standard communication protocol conversion is carried out to off-gauge interface type, i.e., by communication Protocol Conversion firmware by off-gauge interface class
Communication Protocol Conversion specified by type is the communication protocol specified by the interface type of standard.
For example, measurand uses sub-LVDS interfaces, and all-in-one formula IMAQ detector uses MIPI interfaces.
Establish and fail when communication connection, that is, know that measurand employs off-gauge interface type, then all-in-one formula figure
As loading communication Protocol Conversion firmware in acquisition testing instrument, the communication Protocol Conversion that sub-LVDS interfaces are specified is MIPI interfaces
The communication protocol specified, and then realize that the communication connection between measurand and all-in-one formula IMAQ detector is successfully built
It is vertical.
In the presence of above-described embodiment, the attachable interface type of all-in-one formula IMAQ detector is extended, i.e.,
The attachable interface type of all-in-one formula IMAQ detector is not limited to the interface type of standard, can also be off-gauge and connects
Mouth type, is effectively improved compatibility of the all-in-one formula IMAQ detector to different interface type, and then enter one with this

In order that the view data generated in measurand can reach good imaging when terminal device is shown
Effect, some parameters would generally be stored in measurand, for example, being illustrated by camera module of measurand, those ginsengs
Number can be camera lens correction parameter, white balance parameter, Focusing parameter etc..When terminal device carries out image display, just can
By reading those stored parameters in measurand and applying on the image of display, school is carried out with this image to display
Standard, and then realize good imaging effect.
Thus, one-off programming burning is to refer to that carrying out image calibration to the view data generated in measurand is somebody's turn to do
A little parameters, and then by those parameter read-in measurands.
Burning information is those parameters that the view data generated in measurand is carried out image calibration and obtained.
Step 530, the view data that measurand is completed to generate after the write-in of burning information is received, is sentenced by the view data
Whether burning is successful for disconnected measurand.
If measurand burning failure, then it represents that the burning information stored in measurand is led there occurs mistake
Measurand is caused to scrap, now, measurand is moved to defective products region by main controller controls manipulator.
Further, the view data that measurand is completed to generate after the write-in of burning information can be complete by measurand
Actively send to all-in-one formula IMAQ detector, can also be by all-in-one formula IMAQ after being write into burning information

The corresponding view data of object requests is surveyed, is not limited herein.
In the presence of above-described embodiment, realize one-off programming burning and only adopted in measurand and all-in-one formula image
Carried out between collection detector, and then cause the collection of any view data only to need to implement transmission between said two devices
, avoid interacting with image detecting apparatus, substantially reduce the transmission time of view data, one-off programming is improved with this
The efficiency of burning.
Further, since the nodes passed through in view data transmitting procedure are reduced, it can fully ensure IMAQ
The stability of detecting system, and then be advantageous to improve the production efficiency of camera module.
In one embodiment, before step 530, method as described above also includes：
Receive the burning that measurand is completed to feed back after the write-in of burning information and complete instruction, and according to burning complete instruction to
Measurand initiates image data acquiring request, the view data generated with obtaining measurand to complete after the write-in of burning information.
For measurand, when completing the write-in of burning information, that is, one-off programming burning is completed, now, be tested
Object will generate burning and complete to instruct and send to all-in-one formula IMAQ detector.Wherein, the burning complete instruction by with
One-off programming burning has been completed in instruction measurand.
For all-in-one formula IMAQ detector, after measurand generates and sends burning completion instruction,
Just the burning can be received and complete instruction, know that measurand has completed one-off programming burning with this, and then to tested pair
As the view data that is generated after the write-in of burning information is completed in request, with according to the view data judge measurand whether burning into
Work(.

Cause, then judge measurand burning success.
After measurand completes the write-in of burning information, measurand is in test scene corresponding to mechanism for testing to field
Scape drawing is shot, and will generate view data.
Correspondingly, all-in-one formula IMAQ detector just can receive measurand and complete one-off programming burning
The view data generated afterwards, and according to the view data judge measurand whether burning success.
Specifically, it is compared by the burning information for generating image calibration twice respectively, if the two is consistent, is sentenced
Determine measurand burning success.
, whereas if the two is otherwise varied, then measurand burning failure is judged, that is, represent the burning stored in measurand
Information is recorded there occurs mistake, and then causes measurand to be scrapped, now, is moved measurand by main controller controls manipulator
Move to defective products region.
By process as described above, using burning information twice unanimously as measurand burning successfully judgement according to

It object, can be camera module, can also be the image sensor chip in camera module.Object is with being tested
Can mutually it be converted between object, i.e., when needing to implement IMAQ detection process for object, the object is measurand.
It should be appreciated that if the object identity of object is IIC mailing addresses, the limited bit of IIC mailing addresses is limited to
Position (being usually 7 bits, be then simply possible to use in and represent 128 object identities), it is identical to have an object identity of different objects,
Some configuration parameters may be associated by turn resulting in preset data library file same target mark, and some configuration parameters
Different objects is corresponded to respectively.
Thus, just can be according to object identity by being found in preset data library file pair after object identity is obtained

So-called traversal refers to, when measurand loads previous configuration parameter failure, continue to load the latter configuration ginseng
Number.Further, traversal can be according to the progress of specified order or random progress, not be defined herein.
By process as described above, configuration parameter adaptive allocation is realized, avoids manually participating in, is advantageous to raising figure
As detection efficiency, and then be advantageous to improve the production efficiency of camera module.
As shown in figure 8, in one embodiment, step 323 includes：
Step 3231, the configuration parameter arrived according to associative search generates configuration parameter list.
Configuration parameter list be used to store the configuration parameter that associative search arrives.
Specifically, in the generating process of configuration parameter list, the configuration parameter list that has created first, then association is looked into
The configuration parameter found is added to the configuration parameter list successively, and then causes the configuration parameter in the configuration parameter list
With putting in order, i.e. order of addition.
For example, first configuration parameter added to configuration parameter list is considered as making number one, by that analogy, finally
One configuration parameter added to configuration parameter list is considered as rolling into last place.
Step 3232, the configuration in configuration parameter list is joined according to putting in order for configuration parameter in configuration parameter list
Number is loaded onto measurand successively.
In the present embodiment, the traversal of configuration parameter is carried out in sequence, i.e. is joined according to being configured in configuration parameter list
Several progress that puts in order.
Certainly, in other embodiments, if in a manner of queue to associative search to configuration parameter store,
It is the adaptive allocation that configuration parameter is carried out according to the order of first in first out in queue.
Further, when the configuration parameter in configuration parameter list completes adaptive allocation, if measurand does not add yet
Configuration parameter success is carried, then measurand is considered as defective products, now, measurand is moved into defective products area by manipulator
Domain.
, whereas if any configuration parameter causes measurand loading configuration parameter success in configuration parameter list, then jump
Rotate into step 3233, stop traversal.
Step 3233, measurand loading configuration parameter success is treated, stops traversal.
As shown in figure 9, in one embodiment, step 3232 includes：
Step 3232a, the wherein configuration parameter in configuration parameter list is loaded onto measurand.
For measurand, a wherein configuration parameter is write in the pre-register of itself, and then pass through write-in
The pre-register of configuration parameter enters normal operating conditions.
Step 3232b, the working condition that measurand is read by communicating to connect identify.
Because same target mark may be associated some configuration parameters, and some configuration parameters correspond to difference respectively
Object, this by cause associative search to configuration parameter not necessarily correspond to measurand.It is appreciated that if preset post
The configuration parameter write in storage is measurand, then measurand will enter normal operating conditions, whereas if preset post
The configuration parameter write in storage is not measurand, then measurand will be unable to normal work, i.e., in abnormal work shape
State.
Therefore, judge whether measurand loading configuration parameter succeeds, that is, judge whether measurand is in normal work
State.
In the present embodiment, working condition mark is used to indicate that whether measurand is in normal operating conditions.Correspondingly,
Working condition by obtaining measurand, which identifies, can determine whether measurand is in normal operating conditions.
Specifically, working condition mark is indicated by the numerical value in register.If measurand enters normal work
Make state, then the numerical value in the register is set to 1, now, working condition mark instruction measurand is in normal work shape
State.Otherwise, the numerical value in the register is set to 0 by measurand, and now, working condition mark instruction measurand is in abnormal
Working condition.
Correspondingly, all-in-one formula IMAQ detector can be entered by communicating to connect the numerical value read in the register
And whether it is 1 to judge whether measurand is in normal operating conditions according to the numerical value.
If numerical value be 1, judge measurand be in normal operating conditions, now, measurand loading configuration parameter into
Work(, then redirect into step 3233, stop traversal.Otherwise, when numerical value is 0, judgement measurand is in abnormal operation, this
When, measurand loading wherein configuration parameter failure, then redirect into step 3232c, continue to travel through.
Certainly, the representation of working condition mark can neatly adjust according to practical application scene.
For example, setting a LED in measurand, then working condition mark carries out table by the light and shade change of LED
Show, if LED is bright, working condition mark instruction measurand is in normal operating conditions, whereas if LED is gone out, then
Working condition mark instruction measurand is in abnormal operation.
Or to preset the level signal height of pin output in measurand to represent that working condition identifies, for example,
Default pin output high level signal, working condition mark instruction measurand are in normal operating conditions, preset pin output
Low level signal, then working condition, which identifies, indicates that measurand is in abnormal operation.
Step 3232c, identify instruction measurand in working condition and be not in normal operating conditions, then arrange configuration parameter
Later configuration parameter in table is loaded onto measurand.
When measurand loads the failure of a wherein configuration parameter, continue later configuration parameter in configuration parameter list
Adaptive allocation, until measurand loading configuration parameter success or configuration parameter list in all configuration parameters loaded
Finish.
In one embodiment, method as described above also includes：
In measurand loading configuration parameter success, the configuration parameter for being successfully loaded onto measurand is stored.
Correspondingly, as shown in Figure 10, method as described above also includes：
Step 610, the measurand of all-in-one formula IMAQ detector connection is changed, and establishes all-in-one formula image and adopts
Collect the communication connection between detector and the measurand of replacing.
Step 620, the configuration parameter of storage is loaded onto to the measurand of replacing by the communication connection of foundation.
If the configuration parameter loading of storage is unsuccessful, redirects into step 320, that is, pass through the communication connection pair of foundation
The measurand of replacing carries out configuration parameter loading.
Otherwise, if the configuration parameter of storage loads successfully, redirect into step 330, generated in measurand
Image data acquiring.
Thus, in configuration parameter loading procedure, the configuration parameter that prestores will be preferentially loaded, once load successfully just
Image data acquiring is directly entered, without the adaptive allocation by configuration parameter, substantially reduces measurand by upper electricity
To the time for entering normal operating conditions, be advantageous to improve image detection efficiency, and then be advantageous to improve the life of camera module
Produce efficiency.
In one embodiment, method as described above also includes：
Step 710, in measurand loading, configuration parameter is unsuccessful or measurand does not pass through and specifies classification image to examine
During survey, generate for indicating decision instruction of the measurand for defective products.
If measurand loading configuration parameter is unsuccessful or measurand is not by specifying classification image detection, that is, represent
Measurand is defective products, correspondingly, will generate and is used to indicate decision instruction of the measurand for defective products.
If whether measurand loading configuration parameter success, determine whether measurand by specifying classification image to examine
Survey, if measurand by specifying classification image detection, that is, represents that measurand is non-defective unit, correspondingly, generation is used to refer to
Show the decision instruction that measurand is non-defective unit.
Step 720, decision instruction is sent to the master controller being connected with all-in-one formula IMAQ detector, to pass through master
Controller control machinery hand carries out defective products classification to measurand.
For master controller, after decision instruction is received, it can know that measurand is according to decision instruction
No is defective products, and then control machinery hand is sorted out to measurand.
Specifically, if decision instruction instruction measurand is defective products, measurand is moved to by control machinery hand
