Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
Embodiment one
With reference to Fig. 1, Fig. 1 is a kind of image processing method flow chart provided in this embodiment, be can specifically include:
S101: base map and coverage diagram are predefined, wherein the pixel on the base map and the coverage diagram has one by one
Corresponding relationship.
Image processing method in the present embodiment actually carries out map overlay processing to two pictures.So first
It needs to be determined that two pictures are respectively as base map and coverage diagram.Specifically, if to realize the map overlay of base map and coverage diagram,
Then the pixel on the base map and the coverage diagram has one-to-one relationship.Specially map overlay when two open and mutually covered on figure
Pixel there is one-to-one relationship.
S102: using it is any to the pixel with one-to-one relationship as process object, wherein in the process object
Pixel on the base map is known as base map pixel, and the pixel being located on the coverage diagram in the process object claims
For coverage diagram pixel.
The present embodiment is using a pair of of pixel with one-to-one relationship as process object, wherein the process object
In, the pixel on the base map is known as base map pixel, and the pixel on the coverage diagram is known as covering image
Vegetarian refreshments.It is understood that when the pixel in base map and coverage diagram with one-to-one relationship is all as having dealt with objects
After processing, the base map and the coverage diagram just complete map overlay.
S103: with any Color Channel in three Color Channels of red, green, blue for Color Channel to be processed, acquisition is based on
The brightness of the base map pixel of the Color Channel to be processed, the brightness of the coverage diagram pixel, the coverage diagram
Transparency.
Since base map and coverage diagram all have three Color Channels of red, green, blue, so, current embodiment require that being based respectively on
Three Color Channels, to the pixel on base map and coverage diagram with one-to-one relationship to handling.That is, by figure

Value may exist a tolerable section, as median luminance value can be set to 0.5 as in the default tolerable section at midpoint
Any value.
If the brightness of the base map pixel is no more than the median luminance value, by the bright of the base map pixel
K times of the product of the transparency of degree, the brightness of the coverage diagram pixel and the coverage diagram, is determined as to the process object
Intermediate result that treated, wherein it is any value within the scope of the pre-set interval at midpoint, preferred value 2 that k, which is with 2,.
If the brightness of the base map pixel be greater than the median luminance value, by the brightness of the base map pixel with
M times of the sum of the brightness of the coverage diagram pixel is determined as first to process object treated the intermediate result
Point；It is determined as the brightness of the base map pixel and n times of the product of the brightness of the coverage diagram pixel to the processing pair
As the second part of treated intermediate result；By the second part of the first part of the intermediate result and the intermediate result
Difference subtract P after, then with the transparency of the coverage diagram do product, obtain to the process object treated intermediate knot
Fruit；Wherein, m and n is with 2 for any value within the scope of the pre-set interval at midpoint, preferred value 2；It is the pre- of midpoint that P, which is with 1,
If any value in interval range, preferred value 1.
In practical application, after determining to process object treated the intermediate result, the intermediate result, institute are utilized
It states the brightness of base map pixel and the transparency of the coverage diagram, determines to bright in the process object treated result
Degree, specifically, being determined as the difference of Q and the transparency of the coverage diagram multiplied by the brightness of the base map pixel to described
The first part of process object treated result；By the first part and institute to process object treated the result
Sum to process object treated the intermediate result is stated, is determined as to bright in the result that deals with objects that treated
Degree, wherein it is any value within the scope of the pre-set interval at midpoint, preferred value 1 that Q, which is with 1,.
