Embodiment
In order to make technical scheme of the present invention clearly, understand, to develop simultaneously embodiment referring to accompanying drawing, scheme of the present invention be described in further detail.
Fig. 1 is the flow chart of intelligent image grasp shoot method embodiment of the present invention.As shown in Figure 1,11 ~ 12 are comprised the following steps.
Step 11: high-definition intelligent network cameras determines that the current candid photograph type that will carry out is bayonet socket video capture, closes the light compensating lamp belonging to the first light filling pattern in N number of light compensating lamp of self correspondence; Wherein, light filling pattern comprises the first light filling pattern and the second light filling pattern, and the first light filling pattern is quick-fried sudden strain of a muscle pattern, and the second light filling pattern is different flash patterns, N be greater than 1 positive integer, comprise the light compensating lamp of different flash patterns and the light compensating lamp of quick-fried sudden strain of a muscle pattern in N number of light compensating lamp simultaneously.
As a rule, the candid photograph type carried out comprises bayonet socket video capture and video capture violating the regulations.
Such as, capture crossing one, when signal lamp is in red light phase, can video capture violating the regulations be carried out, when signal lamp is in green light phase, can bayonet socket video capture be carried out; The effect of bayonet socket image was mainly carried out car record and carried out vehicle count etc., usually car plate and vehicle can be seen clearly, requirement is not done for out of Memory, and image violating the regulations is except needs see vehicle and vehicle clearly, also need to see the more accurately detailed information such as body color clearly, that is, the imaging requirements of two kinds of images is different, therefore can use no light filling mode.
In actual applications, according to existing mode, high-definition intelligent network cameras can determine that the current candid photograph type that will carry out is bayonet socket video capture still video capture violating the regulations.
When for bayonet socket video capture, high-definition intelligent network cameras can determine the light filling pattern of N number of light compensating lamp of self correspondence successively, N be greater than 1 positive integer, concrete value is depending on actual conditions, and in N number of light compensating lamp, both there is the light compensating lamp of quick-fried sudden strain of a muscle pattern, there is again the light compensating lamp of different flash patterns, such as, when the value of N is 3, the light compensating lamp of 2 quick-fried sudden strain of a muscle patterns and the light compensating lamp of 1 different flash patterns can be comprised, for the light compensating lamp of quick-fried sudden strain of a muscle pattern, can be closed, even it is onset no longer, the light compensating lamp only leaving different flash patterns carries out light filling, the imaging requirements of bayonet socket image can be met, thus decrease light pollution, and pass through the access times of the light compensating lamp reducing quick-fried sudden strain of a muscle pattern, extend the useful life of the light compensating lamp of quick-fried sudden strain of a muscle pattern.
When for video capture violating the regulations, high-definition intelligent network cameras can determine the light filling pattern of N number of light compensating lamp of self correspondence successively, and closes the light compensating lamp wherein belonging to different flash patterns, and the light compensating lamp only leaving quick-fried sudden strain of a muscle pattern carries out light filling.
Because the light compensating lamp of different flash patterns carries out light filling by orienting reflex, and the reflecting effect that the material of car plate and structural design determine it is best, like this, if while utilizing the light compensating lamp of quick-fried sudden strain of a muscle pattern to carry out light filling, the auxiliary light compensating lamp of different flash patterns that uses carries out light filling, may cause car plate overexposure, None-identified and identification, therefore, while utilizing the light compensating lamp of quick-fried sudden strain of a muscle pattern to carry out light filling, need the light compensating lamp of closing different flash patterns.
Step 12: high-definition intelligent network cameras is arranged captures with this exposure parameter matched, and completes this candid photograph according to set exposure parameter and the light compensating lamp of not closing.
For each candid photograph, high-definition intelligent network cameras carries out except Based Intelligent Control except needing to the light filling mode of light compensating lamp, also needs to arrange to capture with this exposure parameter matched, and namely carries out Based Intelligent Control to the dependent imaging parameter of camera.
The feature of the light compensating lamp of quick-fried sudden strain of a muscle pattern is concentration of energy, onset time is short, can illuminate bulk zone at the energy capturing abrupt release, and surround lighting is little on the impact of capturing, need during candid photograph to control the time for exposure, make the maximum exposure time slightly larger than the effective acting time of light compensating lamp, but if long, when surround lighting is very weak, signal lamp can cause colour cast by overexposure, if too short, then the energy of light compensating lamp is not fully utilized, and image effect does not reach the best yet.
The light compensating lamp of different flash patterns is generally light-emitting diode (LED, LightEmittingDiode) lamp, feature is that energy is relatively weak, spot size is indefinite, the energy shortage of abrupt release is to illuminate whole scene, surround lighting on capture impact relatively large, therefore need by lengthen capture the time for exposure promote surround lighting more weak time integral image brightness.
According to the light compensating lamp of quick-fried sudden strain of a muscle pattern and the light compensating lamp feature separately of different flash patterns of above introduction, when capturing at every turn, high-definition intelligent network cameras all needs to arrange captures with this exposure parameter matched, and described exposure parameter comprises shutter and gain etc.
