As shown in Figure 3, be the process flow diagram that camera lens of the present invention pollutes real-time detection method preferred embodiment.
Step S1, request module 11 asks the first lighting apparatus 40 of described picture pick-up device 100 and the second lighting apparatus 50 to return real-time lighting intensity level.For example described the first lighting apparatus 40 receives the illumination intensity value 285luxes(Lux of the light beam that sees through camera lens 20 being detected after this request) return to described camera lens and pollute real-time detecting system 10.The illumination intensity value 300luxes that described the second lighting apparatus 50 receives the extraneous light beam of the picture pick-up device 100 being detected after this request returns to described camera lens and pollutes real-time detecting system 10.
Step S2, receiver module 12 receives the real-time lighting intensity level that described the first lighting apparatus 40 and the second lighting apparatus 50 return.
The illumination intensity value that for example receives the light beam that sees through camera lens 20 that described the first lighting apparatus 40 returns is 285luxes, and the illumination intensity value that receives the extraneous light beam of the picture pick-up device 100 that described the second lighting apparatus 50 returns is 300luxes.
Step S3, the illumination intensity value that the illumination intensity value that computing module 13 returns described the first lighting apparatus 40 returns divided by described the second lighting apparatus 50 is to obtain the ratio of an illumination intensity value.The ratio that for example, gets illumination intensity value after the illumination intensity value 300luxes that the illumination intensity value 285luxes, described the first lighting apparatus 40 being returned returns divided by described the second lighting apparatus 50 is 0.95.
It should be noted that, what described ratio reacted is to see through the intensity of illumination of light beam of camera lens 20 and the intensity of illumination degree of closeness of the extraneous light beam of picture pick-up device 100, for example, in the situation that camera lens 20 is not subject to polluting, the ratio of described illumination intensity value can reach 1(hypothesis camera lens 20 itself to the intensity of illumination of light beam without weakening), and once camera lens 20 is polluted, the intensity of illumination of the light beam that sees through camera lens 20 is weakened, thereby cause the ratio of obtained intensity of illumination can be less than 1.
Step S4, judge module 14 judges whether the ratio of obtained intensity of illumination is less than preset value, if so, performs step S5, otherwise process ends.
For example, for example preset value is 0.98, is less than preset value according to intensity of illumination ratio 0.95 and 0.98 can judges camera lens 20 and polluted, and now carries out process step S5.
It should be noted that, described preset value can arrange according to the actual requirements, can be by the ratio that more approaches the intensity of illumination that camera lens 20 can reach in the situation that not being subject to polluting of described preset value setting if lens cleaning degree is had relatively high expectations.
Step S5, execution module 15 is opened scrubbing pilot lamp 30 and is reminded staff to carry out abatement processes to camera lens 20.For example, in the time that judgement show that camera lens 20 is subject to polluting, execution module 15 can make described scrubbing pilot lamp 30 in opening by the GPIO on the mainboard of control picture pick-up device 100, for example open after scrubbing pilot lamp 30, described scrubbing pilot lamp 30 sends blinking light, reminds staff need carry out to camera lens 20 object of abatement processes thereby reach.Sending module 16 sends mail by network need carry out abatement processes to staff to camera lens 20 with prompting staff.
It should be noted that, if not network enabled agreement of described picture pick-up device 100 cannot be connected to network, can only remind staff to carry out abatement processes to camera lens 20 by opening scrubbing pilot lamp 30.
Step S6, after staff is to described camera lens abatement processes, whether the ratio of described judge module 14 intensity of illumination that further judgement is obtained is less than preset value, if not, perform step S7, if so, described judge module 14 continues to judge whether the ratio of the intensity of illumination of obtaining is less than preset value.
For example, when staff carries out after abatement processes described scrubbing pilot lamp 30, described judge module 14 judgements draw when the ratio of obtained intensity of illumination is more than or equal to preset value, the cleanliness that judge described camera lens 20 meet the requirements, now perform step S7, otherwise, if described judge module 14 judgements show that the ratio of obtained intensity of illumination is still less than preset value, the cleanliness that judge this scrubbing pilot lamp 30 are still undesirable, will be held open state by described scrubbing pilot lamp 30, continue to remind staff to carry out abatement processes to described camera lens 20, now described judge module 14 continues to judge whether the ratio of the intensity of illumination of obtaining is less than preset value.
Step S7, execution module 15 is closed described scrubbing pilot lamp 30.For example, when at step S6, judgement draws when the cleanliness of camera lens 20 meet the requirements, described execution module 15 can be closed described scrubbing pilot lamp 30 by the GPIO on the mainboard of control picture pick-up device 100, with prompting staff camera lens 20, after abatement processes, the cleanliness of this camera lens 20 meet the requirements.
