Figure.
As shown in figure 4, focusing for the vehicle-mounted wide-angle camera of the present embodiment and focusing and encapsulation process for package system 100
Comprise the following steps:
Step S1:Start focusing and package system 100 for vehicle-mounted wide-angle camera, allow system to be in holding state, then
Into step S2.
Step S2:Camera lens and sensor module 7 are installed;Fixed wide-angle part stuck-module front-end module 4 is used for fixed need
The wide-angle lens to be assembled, the position of fixed wide-angle part stuck-module front-end module 4 can be adjusted according to required size, so that
Reduce the device offset error during focusing;Fixed wide-angle part stuck-module terminus module 5 be used to fixing wide-angle lens with
Cmos sensor connected with outer casing, and image transmitting data wire is connected, the image such that it is able to be collected into during focusing is passed
It is defeated by measurement module 11.Equally, the position of fixed wide-angle part stuck-module terminus module 5 can also be adjusted, so as to reduce determine
Device offset error during Jiao.Cmos sensor is located at the flexible front end of catch bar module 6, for sensor PCB positions
It is fixed, while rocking in the flexible progradation of catch bar module 6 sensor PCB core piece is also avoided, subsequently into step S3
Step S3:PC modules 12 initialize driving stepper motor module 9, flexible catch bar mould by motion state module 8
Block 6, fixed wide-angle part stuck-module front-end module 4, fixed wide-angle part stuck-module terminus module 5 and centralized positioning laser
Module 3, allows them to be in initial set up position.Subsequently into step S4.
Step S4:Centralized positioning laser module 3 is set and physical centre's point is positioned, the control centre of PC modules 12 determines
Position laser module 3 is started working, and here using camera lens physical centre independent positioning method, is flashed by weak laser, judges that laser is worn
Cross wide-angle lens reach cmos sensor time whether with as the time for receiving reflected light.If laser two-way time differs
Sample, then finely tune fixed wide-angle part stuck-module front-end module 4 and fixed wide-angle part fixed by driving stepper motor module 9
The position of end of module module 5, trimming movement ensures centralized positioning laser module 3, fixed wide-angle by stepper motor completion
Physical centre's point of part stuck-module front-end module 4, fixed wide-angle part stuck-module terminus module 5 and cmos sensor
In straight line.If the time is the same, show wide-angle lens with the point location completion of cmos sensor physical centre, now stepping electricity
The control centre of machine drive module 9 positioning laser module 3 declines, the stepper motor that down maneuver passes through centralized positioning laser module 3
Complete.Subsequently into step S5
Step S5:Test focus image module is set and closed loop is carried out and is focused;PC modules 12 set test focus chart as mould
Block 1 is started working.Driving stepper motor module 9 is used to control the advance of flexible catch bar module 6, here using stepper motor,
Small yardstick displacement can be accomplished, coordinate the white light of LED light source 2 flicker of test focus image module 1, sensor chip is gathered
A series of images is transferred to PC modules 12 by measurement module 11.PC modules 12 use DSP digital signal processing chips, to collection
To image carry out Fast Fourier Transform (FFT) and extract characteristic value being compared with preset state characteristic value, so that it is determined that flexible promotion
Whether bar module front end adsorption section reaches wide-angle lens focal point.Use DSP main control chips and coordinate with quick parser, can
Real-time inspection is carried out to focus process to it, formation focuses the closed-loop control of process.Meanwhile, in order to prevent flexible catch bar module
In wide-angle lens focal length, actual parameter that can be in advance according to wide-angle lens presses the calculating of focal length computing formula to 6 initial position
Go out the substantially focal range of every kind of wide-angle lens, then the initial position of the flexible catch bar module 6 of system is set in focal range
Outside, it is ensured that system can be with normal work.Subsequently into step S6.
Step S6:Encapsulation control module is set;Measurement module 11 can send instructions to PC modules 12.When PC modules 12 are received
After closed loop focuses completion instruction, test focus image module 1, encapsulation control module 10 and motion state module 8 are sent instructions to
Carry out ensuing operation.Now, test focus image module 1 focuses completion instruction receiving the closed loop that PC modules 12 send
Control LED light source 2 stops flicker afterwards.Meanwhile, driving stepper motor module 9 is receiving the closed loop that motion state module 8 sends
The flexible catch bar module 6 of control keeps current state after focusing completion instruction.Significantly, since dsp chip is extremely strong
Conversion promotes bar portion actual displacement amount minimum to flexible after computing capability and Design of Stepper Motor Subdivision control, so for above-mentioned step
Rapid control can be completed in a short period of time, be not in the situation for missing wide-angle lens focus.Subsequently into step S7.
Step S7:Wide-angle lens module packaging;After encapsulation control module 10 obtains encapsulation instruction, can be by stretching for obtaining
The range information of contracting catch bar module 6 come drive encapsulation step motor control fix glue rifle reach specified location be irrigated.System
System calculates the size and glue rifle infusion time of glue consumption according to the size of initial wide-angle camera module automatically, and the present embodiment is determined
Glue rifle infusion time is generally located on 1 second or so in burnt and package system.Completing post package control module 10 in perfusion will not stand
Provide encapsulation and complete instruction, but to postpone to send instruction again in several seconds.This is to ensure wide-angle lens and cmos sensor
Adhesion completely, will not fall off.Subsequently into step S8.
Step S8:Packaging effect is checked, after encapsulation control module 10 is sent to the encapsulation of PC modules 12 completes instruction, PC moulds
Block 12 judges that signal is errorless, sends and checks encapsulation instruction to motion state module 8.Now, motion state module 8 sends instruction and allows
The flexible front end adsorption section of catch bar module 6 stops absorption, and acts driving stepper motor module 9, the flexible catch bar mould of control
Block 6 returns to initial position.After the completion of above-mentioned action, PC modules 12 send the LED light source for instructing and allowing and test focus image module 1
2 complete a blinking action.Wide-angle camera module after the completion of now encapsulating can collect piece image, by measurement module
11 are sent to PC modules 12.Image feature value is extracted by dsp chip and fast Fourier algorithm in PC modules 12, works as system
When judging that the image that camera module is collected does not have obvious gray difference, show that cmos sensor has been mounted to specific bit
Put and encapsulate completion.Subsequently into step S9
Step S9:System reset;PC modules 12 send encapsulation END instruction to motion state module 8, and it can control to fix
The fixed position of wide-angle part stuck-module front-end module 4 and fixed wide-angle part stuck-module terminus module 5 unclamps, and is easy to take the photograph
As head dismounting.Meanwhile, the system reset of PC modules 12 is easy to development the following group camera to focus and encapsulate work to initial setting state
Sequence.Subsequently into done state.
The effect of embodiment and effect
Vehicle-mounted wide-angle camera according to involved by the present embodiment is focused and package system, because the first output end, test
Focus image module, image sensor module, measurement module and first input end are sequentially connected with, the second output end, motion shape
