Technical field
The present invention relates to a kind of thermal imaging focuses on method for trimming, specifically, it is a kind of thermal imaging based on key press time
Method for trimming is focused on, is belonged to thermal imaging and is focused on fine setting technical field.
Background technology
Thermal imaging is to detect infrared energy by noncontact（Heat）, and the signal of telecommunication is converted into, and then in display
Upper generation thermal image and temperature value, it is possible to a kind of testing equipment that temperature value is calculated.Thermal imaging system is typically by two
Part is constituted：Heat detector and thermal imagery camera lens, both complement each other indispensable, and the quality that imaging lens are focused on is determined
The definition of output image.
In the focusing of imaging lens, the relative position of eyeglass passes through electro-motor（Direct current generator）Determine,
Certain focal length（Camera lens zoom value）Only on the LAP of electro-motor very little, this results in the focus point of upper camera lens
When user focuses on, multiple button focusing effect is all undesirable.And this undesirable situation is mostly due to electricity
Dynamic motor stroke is beyond scope to be focused on, or perhaps electro-motor jiggle effect is too poor, result in showing of gathering
As occurring.The generation of this phenomenon can be solved from hardware, change the good electro-motor of jiggle effect.But if use this side
Formula, one side camera lens cost will certainly will increase, and another aspect different the body constitution even response time of the user of different age group are all
It is different, which results in when user is in vernier focusing, the stroke that focuses on of electro-motor has very big difference, presses in click
Under the manipulation of the fast people of button, may focus on very normally, but when you click on button and slow, the electro-motor that may be focused on
Can walk far again, cause Consumer's Experience very poor.
The content of the invention
For the defect of prior art, the technical problem to be solved in the present invention be to provide a kind of heat based on key press time into
Image focu method for trimming, need not do the change on hardware, and just can focus on used motor to thermal imaging carries out accurate fine motion
Control, and the key response time scalable of user, it is to avoid the different user response time, different phenomenon occurred.
In order to solve the technical problem, the technical solution used in the present invention is：A kind of thermal imaging based on key press time
Method for trimming is focused on, be the method comprising the steps of：1st, the key response time is set；2nd, during main control chip detection actual key
Between, and compare the size of actual key time and key response time；If the 3, the actual key time is less than the key response time, main
Control chip controls focus motor is moved according to certain level dutycycle and level retention time；If the 4, the actual key time
Not less than the key response time, then it is defined by detecting operation when stopping focus button.
Thermal imaging based on key press time of the present invention focuses on method for trimming, actuation of keys of the main control chip according to user
Determine the actual key time, when detecting user and pressing focus button, this time point as time zero, is opened by main control chip
Beginning timing, when detecting user and lifting focus button, this time point as timing end point, is stopped timing by main control chip.
Thermal imaging based on key press time of the present invention focuses on method for trimming, and the key response time is sent by host computer
To main control chip.
Thermal imaging based on key press time of the present invention focuses on method for trimming, and the key response time is by program
The mode of middle fixation is configured.
Thermal imaging based on key press time of the present invention focuses on method for trimming, and the key response time is 180 ±
100ms。
Thermal imaging based on key press time of the present invention focuses on method for trimming, is less than key response when the actual key time
During the time, main control chip controls the level pulse dutycycle operation 30ms that focus motor is according to 30% ~ 70%；When the actual key time
During not less than the key response time, main control chip control focus motor is remained on according to 100% dutycycle, until main control chip
Detect.
Beneficial effects of the present invention：Thermal imaging focusing method for trimming based on key press time of the present invention can be arranged to be pressed
Key response time, main control chip are controlled to electro-motor according to the contrast of actual key time and this key response time
System, need not do the change on hardware, and just can focus on used focus motor to thermal imaging carries out accurate fine motion control.And
The key response time scalable of user, avoiding problems different user response time different phenomenon and occurs, solve because
Key press time differentia influence focuses on the phenomenon of jiggle effect, it is ensured that good man-machine interaction.
Description of the drawings
Fig. 1 is the flow chart of the present invention.
Specific embodiment
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
The present embodiment discloses a kind of thermal imaging based on key press time and focuses on method for trimming, and Fig. 1 is the flow chart element of the present invention
Figure, steps of the method are：S01, setting key response time are simultaneously saved into Tim1；S02, main control chip detection are actually pressed
The key time, in the present embodiment, main control chip determines the actual key time by the actuation of keys of user, presses when user is detected
During focus button, this time point as time zero, is started timing by main control chip, and timer count adds 1 per ms；Work as detection
When lifting focus button to user, this time point as timing end point, is stopped timing by main control chip, and timer stops count
Plus 1；S03, main control chip compare being less than for actual key time count and key response time Tim1, if count<Tim1, then
Focus motor is run according to certain level dutycycle, and run time is equal to the level retention time；If count >=Tim1, with
Detect operation when stopping focus button being defined, i.e., focus motor is run by certain dutycycle, stop life when button is detected
Stop after order.
In the present embodiment, the key response time can be sent to main control chip by host computer and be configured, it is also possible to logical
Cross mode fixed in a program to be configured.The determination of Jing many experiments, the short key press time of ordinary people（Press and then lift）
About in 180ms or so, so the setting of key response time can fluctuate in 180ms, float time is not more than ±
100ms, foundation are determined using crowd.When the actual key time key response time is less than, focus motor is according to 30% ~ 70%
Level pulse dutycycle operation 30ms can reach best focus position adjustment, when the actual key time key response is more than or equal to
Between when, focus motor is remained on according to 100% dutycycle, after main control chip detect after button is ceased and desisted order stop.
Thermal imaging based on key press time of the present invention focuses on method for trimming and can arrange key response time, master control core
Piece is controlled to electro-motor according to the contrast of actual key time and this key response time, need not be done on hardware more
Change, just can focus on used focus motor to thermal imaging carries out accurate fine motion control.And the key response time of user
Scalable, avoiding problems different user response time different phenomenon and occurs, solve because key press time differentia influence is poly-
The phenomenon of burnt jiggle effect, it is ensured that good man-machine interaction.
Described above is only the ultimate principle and preferred embodiment of the present invention, and those skilled in the art are done according to the present invention
The improvement for going out and replacement, belong to protection scope of the present invention.
