Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings the calibration method and device of the optical sensor of the embodiment of the present invention are described.
In order to reduce requirement of the production line to optical sensor calibration environment, calibration accuracy and production efficiency, this Shen are improved
It please propose a kind of calibration method of optical sensor.
Fig. 1 is a kind of flow diagram of the calibration method of optical sensor provided by the embodiment of the present invention.
As shown in Figure 1, method includes the following steps:
Step 101, under camera bellows environment, the golden machine of calibration is obtained.
Wherein, golden machine refers to that indices and parameter all reach optimal machine, is mainly used for as Standard Machine to production line
On machine tested.Therefore, in the present embodiment, the gold of calibration can be obtained first in a glitch-free camera bellows environment
Machine, so as to improve the precision of test.
Specifically, the process for obtaining the golden machine of calibration, can be as shown in Figure 2, comprising the following steps:
Step 201, the optical sensor of machine to be selected is irradiated using default light source.
The intensity for the light that default light source issues is the first light intensity, the first light intensity, that is, etalon optical power.
Step 202, the intensity for the light that the optical sensor of machine to be selected receives is detected, and is recorded as the second light intensity.
In the ideal situation, what the intensity for the light that the optical sensor of machine to be selected receives should be issued with default light source
The intensity of light is identical, i.e. the first light intensity.But due to extraneous factors such as manufacture craft or environment, it will lead to optical sensor
The intensity of the light received and the intensity for the light that default light source issues are inconsistent, it is therefore desirable to pass to the optics of machine to be selected
Sensor is calibrated.
Step 203, the optical sensor of machine to be selected is calibrated according to the first light intensity and the second light intensity.
Specifically, the intensity for the light optical sensor of machine to be selected being an actually-received, i.e. the second light intensity calibration
For the first light intensity.
Step 204, using the machine to be selected after calibration as the golden machine of calibration.
It, can be by (it is strong equal to default source emissioning light to receive light intensity) machine to be selected after calibration after above-mentioned steps
The light source of station on production line is calibrated using golden machine as standard as golden machine.
In order to improve efficiency, more machines to be selected can be operated simultaneously, are calibrated to golden machine.
Step 102, it is calibrated using light source of the golden machine to station on production line.
Specifically, it is calibrated using light source of the golden machine to station on production line, it can be as shown in Figure 3, comprising the following steps:
Step 301, the optical sensor of golden machine is irradiated using the light source of station on production line.
Step 302, the intensity for the light that the optical sensor of the golden machine of detection receives, and it is recorded as third light intensity.
Step 303, the intensity of the light of the light source sending of station on production line is adjusted, so that the optical sensor of golden machine connects
The intensity of the light received is from third light intensity calibration to the first light intensity.
Step 304, the intensity for the light that the light source of station issues on the production line after record calibration, i.e. the 4th light intensity.
Due to extraneous factors such as manufacture craft or environment, the intensity for the light that the light source of station issues on production line is also had
It enters and leaves, therefore is also required to calibrate the light source of station on production line using the golden machine of standard, make the strong of the light of its sending
Degree is consistent, that is, is calibrated to the first light intensity.That is, the intensity for the light that the light source of station issues on adjustment production line,
The intensity for the light for receiving the optical sensor of golden machine is adjusted to the first light intensity.Work on the production line adjusted detected
The 4th light intensity of intensity for the light that the light source of position issues, can be confirmed as the first light intensity.
Step 103, it is carried out using optical sensor of the light source of station on the production line after calibration to the machine produced
Calibration.
It, can be using the light source of standard to the machine produced after the light source of station is calibrated on to production line
Optical sensor calibrated.
It specifically, can be as shown in Figure 4, comprising the following steps:
Step 401, using the light source of station on the production line after calibration, with the light for the machine that the irradiation of the 4th light intensity is produced
Learn sensor.
Step 402, the intensity for the light that the optical sensor of the machine produced receives is detected, and is recorded as the 5th light
By force.
Step 403, the optical sensor for the machine produced is calibrated according to the 4th light intensity and the 5th light intensity.
Specifically, calibration factor can be calculated according to the 4th light intensity and the 5th light intensity, then saves calibration factor to right
The machine produced answered, and calibrated using optical sensor of the calibration factor to the corresponding machine produced.
Wherein, calibration factor is the numerical value that the 4th light intensity is obtained divided by the 5th light intensity.
The intensity for the light that the light source of station issues on production line after the actually calibration of 4th light intensity, that is to say, that
4th light intensity is exactly the first light intensity of standard.Intensity (the 5th light for the light that the optical sensor for the machine produced receives
By force), it is had differences with the first light intensity of standard, it is therefore desirable to the optical sensor for the machine produced be calibrated, be it
It is complied with standard in use from now on.
The calibration method of the optical sensor of the embodiment of the present invention, by obtaining the golden machine of calibration under camera bellows environment,
And it is calibrated using light source of the golden machine to station on production line, and utilize the light source of station on the production line after calibration to life
The optical sensor of the machine of output is calibrated, and is calibrated respectively to the light source of station on golden machine and production line, is made its symbol
Standardization, being capable of effective exclusive PCR, requirement of the reduction production line to optical sensor calibration environment, raising calibration accuracy and life
Produce efficiency.
