Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
As shown in fig. 1, which is a schematic structural diagram of the snapshot module of the present application, the snapshot module includes a master control end M and a slave control end N. The master control end M is used for identifying targets in a shooting range, and the slave control end N is used for capturing the targets identified by the master control end. In the practical application process, in order to ensure that there is no snapshot dead angle in the area, a plurality of snapshot modules are generally adjacently arranged to form a combined type camera module, as shown in fig. 2, a first snapshot module and a second snapshot module are adjacently arranged, and in the practical application, the snapshot range of the first snapshot module is a first area a and a second area B, and the snapshot range of the second snapshot module is a second area B and a third area C, wherein the second area B is a common snapshot area of the first snapshot module and the second snapshot module, that is, in the practical application, a target in the second area B can be snapshot by the first snapshot module at the same time and can also be snapshot by the second snapshot module at the same time, which causes repeated snapshot, and further causes system waste. The application provides an image snapshot method for solving the problem of repeated snapshot of a camera module. Referring to fig. 3, a schematic flow chart of a first embodiment of the image capturing method of the present invention specifically includes:
step S11: the method comprises the steps of defining a snapshot range of a first snapshot module of a camera module to be a first area and a second area, and defining a snapshot range of a second snapshot module of the camera module to be a third area and the second area.
The first snapshot module of the camera module is provided with a first area A and a second area B, and the second snapshot module is provided with a second area B and a third area C.
Step S12: the first snapshot module takes a snapshot of the first area and the second area, and the second snapshot module takes a snapshot of the third area; or the first snapshot module takes a snapshot of the first area, and the second snapshot module takes a snapshot of the second area and the third area.
In the actual snapshot process, the first snapshot module is controlled to snapshot the first area A and the second area B, the second snapshot module is controlled to snapshot the third area C, or the first snapshot module is controlled to snapshot the first area A, and the second snapshot module is controlled to snapshot the second area B and the third area C. Therefore, the problem of repeated snapshot can be solved.
In an embodiment, the first snapshot module and the second snapshot module have a unified decision layer for example, and the decision layer defines the snapshot range for the first snapshot module and the second snapshot module respectively. For example, the decision layer defines the first snapshot module as a first area a and a second area B, and defines the second snapshot module as a third area C. At the moment, the master control end M of the first snapshot module identifies all the snapshot targets in the first area A and the second area B, and the slave control end N conducts snapshot on all the snapshot targets in the first area A and the second area B; and the master control end M of the second snapshot module identifies all the snapshot targets in the third area C, and all the snapshot targets in the third area C are snapshot through the slave control end N. For another example, the decision layer defines the capturing range for the first capturing module as the first area a, and defines the capturing range for the second capturing module as the third area C and the second area B. At the moment, the master control end M of the first snapshot module identifies all the snapshot targets in the first area A, and the slave control end N simultaneously conducts snapshot on all the snapshot targets in the first area A; and the master control end M of the second snapshot module identifies all the snapshot targets in the third area C and the second area B, and performs snapshot on all the snapshot targets in the third area C and the second area B through the slave control end N.
In another embodiment, the first capturing module and the second capturing module do not have a unified decision layer as an example for description. The first capturing module and the second capturing module can be defined with respective capturing areas in a manual setting mode. Or, a unified processing layer can be further arranged, the processing layer is respectively associated with the decision layer of the first snapshot module and the decision layer of the second snapshot module, and the decision layer of the first snapshot module and the decision layer of the second snapshot module are controlled by the processing layer to define respective snapshot areas for the first snapshot module and the second snapshot module. By the method, the problem of repeated snapshot is solved, and system loss and system burden are reduced.
In an embodiment, in order to reduce the system load, the capturing areas of the first capturing module and the second capturing module may be set in different time intervals. Referring to fig. 4, a flowchart of a second embodiment of the image capturing method of the present invention specifically includes:
step S21: in a first time period, the first snapshot module takes a snapshot of the first area and the second area, and the second snapshot module takes a snapshot of the third area.
Step S22: in a second time period, the first snapshot module takes a snapshot of the first area, and the second snapshot module takes a snapshot of the second area and the third area.
In a first time period, the first snapshot module takes a snapshot of all the snapshot targets in the first area A and the second area B, and the second snapshot module takes a snapshot of all the snapshot targets in the third area C. In a second time period, the first snapshot module takes a snapshot of all the snapshot targets in the first area A, and the second snapshot module takes a snapshot of all the snapshot targets in the third area C and the second area B.
For example, a 00: 00-12, the capturing range is a first area A and a second area B, and the capturing range is defined as a third area C for the second capturing module. Defining 12 per day for the first snapshot module, either by the decision layer, or the processing layer, or by human: 00 to 00: when 00, the capturing range is the first area a, and the capturing range is defined as the third area C and the second area B for the second capturing module. Then at each day 00: 00-12, the first snapshot module takes a snapshot of all the snapshot targets in the first area A and the second area B, and the second snapshot module takes a snapshot of all the snapshot targets in the third area C. At 12:00 to 00: when the vehicle speed is 00, the first snapshot module takes a snapshot of all the snapshot targets in the first area A, and the second snapshot module takes a snapshot of all the snapshot targets in the third area C and the second area B.
Or, when odd-numbered points of each day are defined for the first snapshot module by a decision layer, a processing layer or a person, the snapshot range is the first area a and the second area B, and the snapshot range is defined for the second snapshot module as the third area C. When the first snapshot module is defined at even points of each day through a decision layer, a processing layer or a person, the snapshot range is defined as a first area A, and the snapshot range is defined as a third area C and a second area B for the second snapshot module. And when the number of the points is odd, the first snapshot module takes a snapshot of all the snapshot targets in the first area A and the second area B, and the second snapshot module takes a snapshot of all the snapshot targets in the third area C. And when the number of the even points is every day, the first snapshot module takes a snapshot of all the snapshot targets in the first area A, and the second snapshot module takes a snapshot of all the snapshot targets in the third area C and the second area B.
Through the method of the embodiment, the first snapshot module and the second snapshot module snapshot the snapshot target in the second area B in different time periods, so that on one hand, the problem of repeated snapshot can be solved, and on the other hand, the system burden can be reduced to a certain extent.
In an embodiment, in order to reduce the system load, a first snapshot module or a second snapshot module may be selected to snapshot a second area B based on the probability of occurrence of a snapshot target in a first area a and a third area C, specifically refer to fig. 5, which is a flowchart of a third embodiment of the image snapshot method of the present invention, and specifically includes:
step S31: and obtaining a first probability that the snapshot target appears in the first area and obtaining a second probability that the snapshot target appears in the third area.
Specifically, the first probability is calculated by using the number of the snap-shot targets appearing in the first region a and the total number of the snap-shot targets appearing in the first region a and the third region C; and calculating to obtain the second probability by using the number of the snap-shot targets appearing in the third area C and the total number of the snap-shot targets appearing in the first area A and the third area C.
In a specific embodiment, the number of the snap-shot objects appearing in the first area a and the number of the snap-shot objects appearing in the third area C may be counted for a period of time. For example, assuming that the snapshot target is a person, a preset time period is selected, and the number of persons appearing in the first area a and the number of persons appearing in the third area C in the preset time period are counted. Calculating a first probability that the snapshot target appears in the first area a by using the sum of the number of persons appearing in the first area a and the third area C, for example: l1= H1/H; where H1 is the number of people present in the first region a, H is the sum of the numbers of people present in the first region a and the third region C, i.e. H = H1+ H2, and H2 is the number of people present in the third region C. A second probability that the snap-shot target appears in the third region C is calculated using the sum of the number of people appearing in the third region C and the number of people appearing in the first region a and the third region C, for example, L2= H2/H.
Step S32: controlling the first snapshot module to snapshot the first area and the second snapshot module to snapshot the third area based on the first probability and the second probability; or controlling the first snapshot module to snapshot the first area, and controlling the second snapshot module to snapshot the second area and the third area.
Specifically, the present embodiment determines the snap-shot object of the second region B based on the first probability L1 and the second probability L2.
In an embodiment, if the first probability L1 is greater than the second probability L2, i.e. L1 > L2, the first capturing module is controlled to capture the first area a, and the second capturing module is controlled to capture the second area B and the third area C. Specifically, the first probability L1 is greater than the second probability L2, which indicates that the number of the snap-shot targets appearing in the first region a is greater than the number of the snap-shot targets appearing in the third region C, and the second snap-shot module is controlled to snap-shot the second region B at this time in order to reduce the system load of the first snap-shot module.
In another embodiment, if the first probability L1 is not greater than the second probability L2, i.e. L1 is less than or equal to L2, the first snapshot module is controlled to snapshot the first area a and the second area B, and the second snapshot module is controlled to snapshot the third area C. Specifically, the first probability L1 is not greater than the second probability L2, which indicates that the number of the snap-shot targets appearing in the first region a is less than or equal to the number of the snap-shot targets appearing in the third region C, and in order to reduce the system load of the second snap-shot module, the first snap-shot module is controlled to snap-shot the second region B. Specifically, if the first probability L1 is smaller than the second probability L2, the second region B is captured by using the first capture module. If the first probability L1= the second probability L2, the second area B may be captured by using the first capture module, and the second area B may also be captured by using the second capture module.
In another embodiment, if the difference between the first probability L1 and the second probability L2 is smaller than a predetermined value L, the second area B is divided into a first subarea B1 close to the first area a and a second subarea B2 close to the third area C; and controlling the first snapshot module to snapshot the first area A and the first sub-area B1, and controlling the second snapshot module to snapshot the third area C and the second sub-area B2. Specifically, the preset value is a reasonable probability value, which can be set by a user according to actual requirements, or can be given by a program, and is not limited specifically. If the first probability | L1-L2| < L is calculated, dividing the second area B into a first sub-area B1 close to the first area A and a second sub-area B2 close to the third area C; and controlling the first snapshot module to snapshot the first area A and the first sub-area B1, and controlling the second snapshot module to snapshot the third area C and the second sub-area B2. In a specific embodiment, the second area B is equally divided into a first sub-area B1 close to the first area a and a second sub-area B2 close to the third area C.
In one embodiment, the decision layer equally divides the second area B into a first sub-area B1 close to the first area a and a second sub-area B2 close to the third area C when drawing the snap-shot areas for the first snap-shot module and the second snap-shot module. And then drawing and defining the area covered by the first area A and the first sub-area B1 as a snapshot area of the first snapshot module, and controlling the first snapshot module to snapshot targets in the area covered by the first area A and the first sub-area B1 when the first snapshot module conducts snapshot. And drawing and defining the area covered by the third area C and the second sub-area B2 as a snapshot area of the second snapshot module, and controlling the second snapshot module to snapshot the target of the area covered by the third area C and the second sub-area B2 when the second snapshot module performs snapshot. Wherein, since the second area B is divided by the decision layer, the decision layer may be divided based on the specific shape of the second area B.
For example, in this embodiment, after the first probability L1 and the second probability L2 are obtained through calculation, whether a difference between the first probability L1 and the second probability L2 is smaller than a preset value L may be first compared, and if so, the second region B is divided into a first sub-region B1 close to the first region a and a second sub-region B2 close to the third region C; and controlling the first snapshot module to snapshot the first area A and the first sub-area B1, and controlling the second snapshot module to snapshot the third area C and the second sub-area B2. If the difference value between the first probability L1 and the second probability L2 is not smaller than the preset value L, the first probability L1 and the second probability L2 are further compared, and the first snapshot module or the second snapshot module is selected to be used for snapshot of the second area B.
According to the method, the snapshot object in the second area B is selected according to the probability of the occurrence of the snapshot targets in the first area A and the third area C, the second area B can be snapshot by using the snapshot module with a small number of snapshot targets, on one hand, the problem of repeated snapshot is solved, and on the other hand, the system load is reduced.
Referring to fig. 6, a schematic flow chart of a fourth embodiment of the image capturing method of the present invention specifically includes:
step S41: obtaining a first probability that a snap-shot object appears in the first area during a historical first time period, and obtaining a second probability that the snap-shot object appears in the third area during the historical first time period.
Specifically, the first probability is calculated by using the number of the snap-shot targets which appear in the first area a in the historical first time period and the total number of the snap-shot targets which appear in the first area a and the third area C in the historical first time period; and calculating to obtain the second probability by using the number of the snapshot targets appearing in the third area C in the historical first time period and the total number of the snapshot targets appearing in the first area A and the third area C in the historical first time period.
In a specific embodiment, the number of snap-shot objects appearing in the first area a and the number of snap-shot objects appearing in the third area C in the first time period of the history may be counted. For example, assuming that the snapshot target is a person, a history first period is selected, and the history first period, the number of persons appearing in the first area a, and the number of persons appearing in the third area C are counted. Calculating a first probability of the snapshot target appearing in the first area a in the first time period in the history by using the sum of the number of the persons appearing in the first area a in the history first time period and the number of the persons appearing in the first area a and the third area C in the history first time period, for example: l3= H3/H0; where H3 is the number of people appearing in the first area a in the first time period, H0 is the sum of the numbers of people appearing in the first area a and the third area C in the first time period, that is, H0= H3+ H4, and H4 is the number of people appearing in the third area C in the first time period. A second probability that the snap-shot object appears in the third area C in the history first period is calculated by using the sum of the number of people appearing in the third area C in the history first period and the number of people appearing in the first area a and the third area C in the history first period, for example, L4= H4/H0.
Step S42: controlling the first snapshot module to snapshot the first area and the second area based on the first probability and the second probability, and controlling the second snapshot module to snapshot the third area; or the first snapshot module is controlled to snapshot the first area, and the second snapshot module is controlled to snapshot the second area and the third area.
Specifically, the snapshot module of the second area B in the first time period corresponding to the historical first time period may be determined according to the first probability and the second probability.
Specifically, in response to the first probability L3 being greater than the second probability L4, the first snapshot module is controlled to snapshot the first area a at the current first time period, and the second snapshot module is controlled to snapshot the second area B and the third area C. The historical first time period and the current first time period are corresponding time periods in two days; or the historical first time period and the current first time period are corresponding time periods in two months. Suppose that the historical first time period is 12 yesterday: 00 to 14:00, if the calculated first probability L3 is greater than the second probability L4, in a first time period (12 to 14 today). Assuming that the historical first time period is 3 months, 9 days to 3 months, 19 days, and the calculated first probability L3 is greater than the second probability L4, the first snapshot module is controlled to snapshot the first area A, and the second snapshot module is controlled to snapshot the second area B and the third area C in the first time period of the month (3 months, 9 days to 3 months, 19 days).
And responding to the fact that the first probability L3 is not larger than the second probability L4, controlling the first snapshot module to snapshot the first area A and the second area B in the current first time period, and controlling the second snapshot module to snapshot the third area C. Suppose that the historical first time period is 12 yesterday: 00 to 14:00, if the calculated first probability L3 is not greater than the second probability L4, the first snapshot module is controlled to snapshot the first area a and the second area B in the first time period (12 to 14. Further, when the first probability L3 is equal to the second probability L4, it may be that 12:00 to 14: when 00 hours, the first snapshot module is used for snapshot of the second area B, and the second snapshot module can also be used for snapshot of the second area B.
And in response to the difference between the first probability and the second probability being smaller than a preset value, dividing the second area B into a first sub-area B1 close to the first area a and a second sub-area B2 close to the third area C.
