Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
Fig. 1 shows the flowchart of the area measurement method that the embodiment of the present invention provides, and details are as follows:
In step S101, obtain the image of target area.
It should be noted that the executive agent of the embodiment of the present invention can be mobile phone or panel computer, it is also possible to for it
He can shoot the device of image, in this no limit.The executive agent of the embodiment of the present invention can be based on Android operation
System, it is also possible to based on iOS or Windows operating system etc., in this no limit.
Wherein, target area can be wall or window etc., in this no limit.The image obtaining target area is permissible
For: the image in photographic subjects region.
In step s 102, calculating the ratio of target area and induction region, wherein, induction region is set in advance in target
In region.
Such as, induction region can be to paste a piece of cloth in the target area in advance, and the color of this block cloth can be prominent
Color, for example, it is possible to be red or green etc..The shape of induction region can be rectangle.
In step s 103, the area of target area is determined according to ratio and the value of induction region that prestores.
In embodiments of the present invention, prestore the value of induction region, such as, prestore the area of induction region, length
And/or it is high.Owing to the value of induction region prestores, therefore, according to the ratio of calculated target area Yu induction region,
And the value of the induction region prestored, it may be determined that the area of target area.
Fig. 2 shows target area 21 and the signal of induction region 22 in the area measurement method that the embodiment of the present invention provides
Figure.
Fig. 3 shows the flowchart that area measurement method one that the embodiment of the present invention provides is exemplary, with reference to Fig. 3:
In step S301, obtain the image of target area.
In step s 302, calculating the ratio of the area of target area and the area of induction region, wherein, induction region is pre-
First arrange in the target area.
In step S303, ratio calculated and the product of the area of the induction region prestored, obtain target area
Area.
As an example of the embodiment of the present invention, calculating target area with the ratio of induction region can be: calculates mesh
The area in mark region and the ratio of the area of induction region.The value of the induction region prestored can be the face of induction region
Long-pending.Owing to the area of induction region prestores, therefore, according to area and the face of induction region of calculated target area
Long-pending ratio, and the area of the induction region prestored, it may be determined that the area of target area.In this example, target

Second limit in territory can be the width of target area.First limit of induction region can be parallel with the first limit of target area
Limit, the second limit of induction region can be the limit parallel with the second limit of target area.Such as, if the length of induction region and target
The length in region is parallel, and the width of induction region is parallel with the width of target area, then the first limit of induction region can be induction region
Length, the second limit of induction region can be the width of induction region.Calculating target area may include that with the ratio of induction region
Calculate first ratio on the first limit of target area and the first limit of induction region, and calculate the second limit and the sensing of target area
Second ratio on second limit in region.The value of the induction region prestored can include the first limit of induction region length and
The length on the second limit of induction region.Owing to the length on the first limit of induction region prestores, therefore, according to target area
First ratio on the first limit of the first limit and induction region, and the length on the first limit of the induction region prestored, permissible
Determine the length on the first limit of target area.Owing to the length on the second limit of induction region prestores, therefore, according to target area
Second limit in territory and second ratio on the second limit of induction region, and the length on the second limit of the induction region prestored,
May determine that the length on the second limit of target area.The length on the first limit according to target area and the second limit of target area
Length, it may be determined that the area of target area.In this example, the first of the length=induction region on the first limit of target area
Length × the first ratio on limit, length × the second ratio on the second limit of the length=induction region on the second limit of target area,
The length on the second limit of the length × target area on the first limit of the area=target area of target area.
It should be noted that in this example, can successively obtain two images, the scope of first image includes target
First limit in region and the limit parallel with the first limit of target area, the scope of second image includes the second of target area
Limit and the limit parallel with the second limit of target area.According to first image, it may be determined that the first limit of target area and sense
Answer first ratio on first limit in region；According to second image, it may be determined that the second limit of target area and induction region
Second ratio on the second limit.
