Mouth, SPI interface, HISPI interfaces etc., ensure that the measurand of different interface type can be with IMAQ detection one with this
Body machine is connected with each other, and the versatility that IMAQ detects all-in-one is improved with this.
After the interconnection of IMAQ detection all-in-one and measurand is completed, master controller just control machinery hand
The IMAQ of interconnection is detected into one of test machine that all-in-one and measurand are moved in some mechanism for testing
Structure, in order to subsequently carry out the image detection of measurand based on one of mechanism for testing.
Step 220, the corresponding test scene of one of mechanism for testing is adjusted by manipulator.
Surveyed as it was previously stated, some mechanism for testing include Jin Jiao scrnario testings mechanism, middle-range scrnario testing mechanism, remote burnt scene

The remote burnt test scene of mechanism for testing simulation.Correspondingly, the view data that measurand is generated in different test scenes will have
Distinguished.
Specifically, in each mechanism for testing testing light source, scene drawing and teleconverter is by according to the survey of given scenario
Strip part is adjusted, and the adjustment to the corresponding test scene of mechanism for testing is realized with this,.Correspondingly, IMAQ detection one
The image detection application program matched with the test scene will be run in body machine, with for the picture number obtained in the test scene
According to the corresponding image detection of progress.
For example, when test structure is as Yuan Jiao scrnario testings mechanism, the test condition of remote burnt scene will be first according to this
Testing light source, scene drawing and teleconverter in mechanism for testing are adjusted, thus by the corresponding test scene of the mechanism for testing
It is adjusted to remote burnt scene.Now, the focusing run with remote burnt scrnario testing authority match is examined in IMAQ detection all-in-one

By process as described above, the automatic streamline cycle operation of image detection is realized, image inspection has fully been ensured
The reliability and stability of survey, are conducive to improving the efficiency of image detection, and then improve the production efficiency of camera module.
In addition, for different test scenes, flowing water cycle operation is carried out using IMAQ detection all-in-one, without
Image capture device and image detecting apparatus are respectively provided with for each mechanism for testing so that IMAQ detecting system is more small-sized
Change, so as to be conducive to the production for reducing camera module to take up an area, advantageously reduce the production cost of camera module.
Except image detection, on the other hand, the view data collected can be carried out to the view data collected
Be also used as measurand carry out one-off programming burning foundation, the one-off programming burning process is illustrated as
Under.
As shown in figure 3, in one embodiment, a kind of method for burn-recording of camera module, applied to IMAQ detection one
Body machine, including：
Step 310, detect that the interface connecting plate that all-in-one is configured connects measurand by IMAQ, set up image and adopt
Communication connection between collection detection all-in-one and its measurand of connection.
Measurand, can be camera module, can also be the image sensor chip in camera module.
Interface connecting plate is a matrix form conversion connector, supports MIPI interfaces, Parallel interfaces, sub-LVDS to connect
Mouth, SPI interface, HiSpi interfaces, USB interface etc., ensure that the measurand of different interface type can be adopted with image with this
Collection detection all-in-one is connected with each other, and the versatility that IMAQ detects all-in-one is improved with this.
Communication connection can be IIC communication connections, can also be that SPI communication is connected, or meet other communication protocols
Connected mode.Correspondingly, the foundation of communication connection is carried out according to the requirement of communication protocol.
After communication connection is set up, it just can pass through the logical of foundation between IMAQ detection all-in-one and measurand
Letter connection carries out data transmission, for example, by communicating to connect transmission configuration parameter.
Step 320, one-off programming burning request is initiated by communicating to connect to measurand, obtains raw in measurand
Into view data.
Step 330, the view data to acquisition carries out image calibration, generates burning information and feeds back to measurand.
In order that the view data generated in measurand can reach good imaging when terminal device is shown
Some parameters would generally be stored in effect, 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 to carry out those parameters that image calibration is obtained to the view data generated in measurand.
Step 340, the view data that measurand completes 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 there occurs mistake, and then lead
Measurand is caused to scrap, now, measurand is moved to defective products region by main controller controls manipulator.
Further, the view data that measurand completes to generate after the write-in of burning information can be complete by measurand
Actively sent after being write into burning information to IMAQ and detect all-in-one, can also be please by IMAQ detection all-in-one
Ask, for example, when IMAQ detection all-in-one knows that measurand completes the write-in of burning information, phase is asked to measurand
The view data answered, is not limited herein.
In the presence of above-described embodiment, one-off programming burning is realized only in measurand and IMAQ detection one
Carried out between body machine, and then cause the collection of any view data to only need to implement transmission i.e. between said two devices
Can, it is to avoid interacted with image detecting apparatus, the transmission time of view data is substantially reduced, improving one-off programming with this burns
The efficiency of record.
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 conducive to improving the production efficiency of camera module.
As shown in figure 4, in one embodiment, after step 310, method as described above also includes：
Step 410, judge whether communication connection is successfully established.If it is, redirecting into step 320.If it is not, then jumping
Rotate into step 420.
Step 420, communication Protocol Conversion firmware is loaded in IMAQ detection all-in-one, it is solid by communication Protocol Conversion
The communication Protocol Conversion that part specifies measurand is that IMAQ detects the communication protocol that all-in-one is specified, so that communication connection
It 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, the compatibility in order to improve the interface connecting plate that IMAQ detection all-in-one is provided, it would be desirable to non-
The interface type of standard carries out standard communication protocol conversion, i.e., by communication Protocol Conversion firmware by off-gauge interface type institute
The communication Protocol Conversion specified is the communication protocol specified by the interface type of standard.
For example, measurand uses sub-LVDS interfaces, and IMAQ detection all-in-one uses MIPI interfaces.
When failure is set up in communication connection, that is, know that measurand employs off-gauge interface type, then IMAQ is examined
Survey and communication Protocol Conversion firmware is loaded in all-in-one, the communication Protocol Conversion that sub-LVDS interfaces are specified is that MIPI interfaces are specified
Communication protocol, and then realize measurand and IMAQ detection all-in-one between communication connection be successfully established.
In the presence of above-described embodiment, IMAQ the detection attachable interface type of all-in-one, i.e. image are extended
The attachable interface type of acquisition testing all-in-one is not limited to the interface type of standard, can also be off-gauge interface type,
Compatibility of the IMAQ detection all-in-one to different interface type is effectively improved with this, and then further increasing figure
As the versatility of acquisition testing all-in-one.
As shown in figure 5, in one embodiment, before step 320, method as described above also includes：
Step 510, configuration parameter adaptive allocation is carried out to the measurand by communicating to connect.
Wherein, the configuration parameter of adaptive allocation is according to the object identity of measurand pass in preset data library file
What joint investigation was found.
Measurand enter normal operating conditions before, i.e., can shooting image with generate IMAQ detect all-in-one
, it is necessary to carry out the configuration of configuration parameter before required view data.The configuration parameter includes but is not limited in camera module
The operating voltage of image sensor chip, interface type, mailing address, picture format, picture size etc..
Thus, after communication connection is set up, IMAQ detection all-in-one transmits configuration parameter to measurand, with
Measurand is set to complete the configuration of configuration parameter.
If measurand loading configuration parameter success, measurand enters normal operating conditions, on the one hand, just can
Image taking is carried out for different test scenes, and then generates the view data in different test scenes so that IMAQ is examined
All-in-one acquisition testing is surveyed, that is, redirects into step 520, on the other hand, redirects into step 320.
, whereas if measurand loading configuration parameter it is unsuccessful, then it represents that measurand can not normal work, that is, be tested
Object is defective products, now, and IMAQ detects that all-in-one will generate the decision instruction for being used for indicating that measurand is defective products
And feeding back to master controller so that measurand is moved to defective products area by master controller according to the decision instruction control machinery hand
Domain.
Further, the corresponding configuration parameter of different measurands is different, thus, in configuration parameter loading procedure
In, by first in preset data library file according to the object identity associative search of measurand to an at least configuration parameter, enter
And the configuration of measurand progress correspondence configuration parameter is guided by configuration parameter adaptive allocation.
By being arranged such, configuration parameter adaptive allocation is realized, it is to avoid artificial to participate in, be conducive to improving image detection
Efficiency, and then be conducive to improving the production efficiency of camera module.
Step 520, in measurand loading configuration parameter success, the view data generated in collection measurand.
Step 530, image detection is carried out to collecting image.
More preferably, by the view data collected point two-way transmission, wherein view data is transmitted to IMAQ all the way
The processor of all-in-one configuration is detected, wherein view data carries out the first specified classification image inspection all the way to this by processor
Survey.Another road view data detects that the interface that all-in-one is configured is transmitted to host computer by IMAQ, to pass through host computer pair
Another road view data carries out second and specifies classification image detection.
In IMAQ detection all-in-one, processor can be ARM core chips, and host computer can be then computer.
Thus, by the transmission of the view data collected point two-way, wherein transmit all the way to processor, another road transmit to
Host computer, and then image detection is performed parallel in IMAQ detects all-in-one and host computer, improved with this
Image detection efficiency, is conducive to improving the production efficiency of camera module.
In addition, if host computer there occurs failure, image detection all can also be held on IMAQ detection all-in-one
OK, being smoothed out for image detection is ensured with this, is conducive to improving the production efficiency of camera module.For example, IMAQ is examined
The working condition that all-in-one reads host computer in real time is surveyed, if the working condition of host computer is abnormal operation, just for figure
As data carry out the image detection of each function.
Further, the running environment of IMAQ detection all-in-one and image detection application program in host computer can phase
Image detection application program in mutually difference, i.e. IMAQ detection all-in-one operates in the first operating system, and in host computer
Image detection application program operate in the second operating system.Wherein, the first operating system is kept for the end installed with measurand
The operating system that end equipment is run is identical, such as (SuSE) Linux OS, and the second operating system is then conducive to improving image inspection
Surveying efficiency, the Windows operating system of algorithm such as needed for suitable for a variety of image detections.
Thus, the detection environment in IMAQ detection all-in-one and practical service environment in measurand are highly consistent,
The confidence level of image detection in IMAQ detection all-in-one is fully ensured that.Meanwhile, the detection environment in host computer is more applicable
The algorithm needed for a variety of image detections, 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, IMAQ detection all-in-one, which provides first, specifies classification image detection, host computer provides second and specifies class
Other image detection.Wherein, computation complexity can be based on by specifying the sorting technique of classification image detection, can also be based on operation effect
Rate, or, based on the demand of camera module manufacturer, the degree of accuracy that image detection is improved with this and efficiency, and then be conducive to
Reduction measurand is mistaken for the probability of defective products.
For example, the image that the image detection application program in processor is operated in (SuSE) Linux OS, host computer
Detection application program operates in Windows operating system, correspondingly, and algorithm needed for the first specified classification image detection can be meter
Calculate complexity relatively low, 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, the production efficiency of camera module is improved.
Or, algorithm secrecy needed for the second specified classification image detection requires 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 Equations of The Second Kind 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
The experience of business.
In one embodiment, before step 5340, method as described above also includes：
Receive the burning that measurand completes 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 IMAQ to detect all-in-one.Wherein, burning completion instruction be used to refer to
Show that measurand has completed one-off programming burning.
For IMAQ detection all-in-one, after measurand generates and sends burning completion instruction, just can
Enough receive the burning and complete instruction, know that measurand has completed one-off programming burning with this, and then please to measurand
The view data for completing to be generated after the write-in of burning information is sought, whether burning is successful to judge measurand according to the view data.
Under the cooperation of above-described embodiment, the collection of view data is controlled by what IMAQ detection all-in-one was actively initiated
Image data acquiring is asked, and is conducive to alleviating the pressure of IMAQ detection all-in-one processing concurrent tasks, and then is conducive to carrying
The image detection efficiency of hi-vision acquisition testing all-in-one.
As shown in fig. 6, in one embodiment, step 340 includes：
Step 341, secondary image calibration is carried out to the view data received, generates secondary burning information.
Step 342, burning information is compared with secondary burning information, if burning information and secondary burning information one
Cause, then judge measurand burning success.
After measurand completes the write-in of burning information, measurand is in the corresponding test scene of mechanism for testing to field
Scape drawing is shot, and will generate view data.
Correspondingly, IMAQ detection all-in-one just can receive measurand life after one-off programming burning is completed
Into view data, and according to the view data judge measurand whether burning success.
Specifically, it is compared, if the two is consistent, is sentenced by the burning information for generating image calibration twice respectively
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
Record information there occurs mistake, and then cause measurand to be scrapped, and now, be moved measurand by main controller controls manipulator
Move to defective products region.
By process as described above, using burning information twice it is consistent successfully judge as measurand burning according to
According to fully ensure that the reliability of IMAQ detecting system with this.
As shown in fig. 7, in one embodiment, step 510 includes：
Step 511, the object identity of measurand is obtained by communicating to connect.
Object identity be used to identify measurand, that is to say, that just can determine measurand by object identity.Example
Such as, object identity can be the IIC mailing addresses of measurand, can also be the hardware device identification code of measurand.
Step 512, according to object identity in preset data library file the corresponding configuration parameter of associative search measurand,
Obtain an at least configuration parameter.
Wherein, the associated storage corresponding object identity of some objects and configuration parameter in preset data library file.
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.
If it should be appreciated that the object identity of object is IIC mailing addresses, being limited to the limited bit of IIC mailing addresses
Position (being usually 7 bits, be then simply possible to use in 128 object identities of expression), the object identity that certainly will have different objects is identical,
Some configuration parameters may be associated by turn resulting in preset data library file same target mark, and some configuration parameters
Different objects are corresponded to respectively.
Thus, after object identity is obtained, just it can be found according to object identity in preset data library file pair
As an at least configuration parameter for mark association.
By being arranged such, realize and configuration parameter is locally stored, it is to avoid transmitted configuration parameter by image detecting apparatus
To the loading procedure of measurand, the load time of configuration parameter is substantially reduced, and then shortens measurand by being power-up to
Into the time of normal operating conditions, so as to be conducive to improving image detection efficiency, and be conducive to 513, according to each configuration ginseng
Several traversals that configuration parameter loading is carried out to measurand, cause measurand to load configuration parameter success by traversal.
After an at least configuration parameter is obtained, each configuration parameter is loaded onto measurand in the way of traversal, directly
To measurand loading configuration parameter success.
So-called traversal refers to, when measurand loads previous configuration parameter failure, continue to load latter configuration ginseng
Number.Further, traversal can be carried out according to specified order or random progress, not be defined herein.
By process as described above, configuration parameter adaptive allocation is realized, it is to avoid artificial to participate in, be conducive to raising to scheme
As detection efficiency, and then be conducive to improving the production efficiency of camera module.
As shown in figure 8, in one embodiment, step 513 includes：
Step 5131, 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 is arrived.
Specifically, in the generating process of configuration parameter list, the configuration parameter list 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 tool in the configuration parameter list
Put 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 5132, the configuration parameter in configuration parameter list is added successively according to putting in order for configuration parameter in configuration parameter list
It is loaded onto measurand.
In the present embodiment, the traversal of configuration parameter is carried out in sequence, i.e. joined according to being configured in configuration parameter list
Several progress that puts in order.
Certainly, in other embodiments, if in the way 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, and measurand is moved into defective products area by manipulator
Domain.
, whereas if any configuration parameter causes measurand to load configuration parameter success in configuration parameter list, then jump
Rotate into step 5133, stop traversal.
Step 5133, measurand loading configuration parameter success is treated, stops traversal.
As shown in figure 9, in one embodiment, step 5132 includes：
Step 5132a, measurand is loaded onto by the wherein configuration parameter in configuration parameter list.
For measurand, a wherein configuration parameter is write in the pre-register of itself, and then passes through write-in
The pre-register of configuration parameter enters normal operating conditions.
Step 5132b, the working condition that measurand is read by communicating to connect is identified.
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.If it is appreciated that 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,
It can determine whether whether measurand is in normal operating conditions by the working condition mark for obtaining measurand.
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 indicates that measurand is in normal work shape
State.Otherwise, the numerical value in the register is set to 0 by measurand, now, and it is abnormal that working condition mark indicates that measurand is in
Working condition.
Correspondingly, IMAQ detection all-in-one just can be by communicating to connect the numerical value read in the register, Jin Ergen
According to the numerical value whether be 1 judge measurand whether be in normal operating conditions.
If numerical value be 1, judge measurand be in normal operating conditions, now, measurand load configuration parameter into
Work(, then redirect into step 5133, stop traversal.Otherwise, when numerical value is 0, judge that measurand is in abnormal operation, this
When, measurand loading wherein configuration parameter failure then redirects into step 5132c, continues to travel through.
Certainly, the representation of working condition mark can neatly be adjusted 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 indicates that measurand is in normal operating conditions, whereas if LED is gone out, then
Working condition mark indicates that measurand is in abnormal operation.
Or, represent that working condition is identified to preset the level signal height of pin output in measurand, for example,
Default pin output high level signal, working condition mark indicates that measurand is in normal operating conditions, presets pin output
Low level signal, then working condition mark instruction measurand is in abnormal operation.
Step 5132c, indicates that measurand is not in normal operating conditions in working condition mark, then arranges configuration parameter
Later configuration parameter in table is loaded onto measurand.
When measurand loads the failure of a wherein configuration parameter, proceed 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 IMAQ detection all-in-one connection is changed, and sets up IMAQ detection all-in-one
Communication connection between the measurand of replacing.
Step 620, the configuration parameter of storage is loaded onto by the communication connection of foundation by the measurand of replacing.
If the configuration parameter loading of storage is unsuccessful, redirects into step 510, that is, pass through the communication connection pair of foundation
The measurand of replacing carries out configuration parameter adaptive allocation.
Otherwise, if the configuration parameter of storage is loaded successfully, redirect into step 320, 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, measurand is substantially reduced by upper electricity
To the time for entering normal operating conditions, be conducive to improving image detection efficiency, and then be conducive to improving the life of camera module
Produce efficiency.
As shown in figure 11, 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, the decision instruction for indicating measurand for defective products is generated.
If measurand loading configuration parameter is unsuccessful or measurand is not by specifying classification image detection, that is, represent
Measurand is defective products, correspondingly, and will generate 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 is by specifying classification image detection, that is, it is non-defective unit to represent measurand, correspondingly, generation is used to refer to
Show the decision instruction that measurand is non-defective unit.
Step 720, send decision instruction and detect the master controller that all-in-one is connected to IMAQ, to pass through main control
Device control machinery hand carries out defective products classification to measurand.
For master controller, after decision instruction is received, just it can know that measurand is according to decision instruction
No is defective products, and then control machinery hand sorts out to measurand.
Specifically, if decision instruction indicates that measurand is defective products, measurand is moved to by control machinery hand
