Abstract
The invention discloses a vehicle navigation picture processing method comprising the following steps: 1, classifying vehicle navigation interface pictures according to different interfaces; 2, connecting to a PC machine, parsing each interface picture according to a preset rule, and separating and marking a picture information portion from a real picture data portion; 3, respectively storing the marked picture information portion and real picture data portion to a selected file; 4, compressing the marked real picture data portion, and storing the compressed marked real picture data portion and the picture information portion to a vehicle navigation storage chip for reading; 5, the vehicle navigation decompresses the compression file, reads the mutually marked picture information portion and the real picture data portion, and an original picture can be synthesized and displayed on a display interface. The method can reduce file quantity in the storage chip, and can reduce vehicle navigation interface picture occupation space and storage chip writing frequency, thus improving vehicle navigation upgrade speed, reducing cost, and improving efficiency.
Description
Technical field
The present invention relates to a kind of vehicle mounted guidance image processing method.
Background technology
At present, picture in vehicle mounted guidance interface is all be placed directly in certain file, then be directly stored in vehicle mounted guidance storage chip, and the operation interface that has many consumers in navigation product, also a lot of picture of needs is just meaned, if these pictures are all placed directly in storage chip, very large space can be taken, but also need to increase storage chip capacity; In addition, the size that picture takes up room also can affect the time of navigational system upgrading, and the read-write number of times of storage chip also can increase in copy procedure, and a lot of file shows mixed and disorderly, bad maintenance in storage chip.
Summary of the invention
Above-mentioned in order to solve, the invention provides a kind of design proposal of vehicle mounted guidance image processing method.
A kind of vehicle mounted guidance image processing method, comprises the following steps: vehicle mounted guidance interface images is classified according to different interface by (1); (2) connect PC, undertaken resolving according to default resolution rules by often opening interface images and pictorial information part and actual picture data division are carried out being separated laggard row labels; (3) the pictorial information part marked and actual picture data division are stored to respectively select files; (4) compress the actual picture data division that marked, and it is to be read to be stored to vehicle mounted guidance storage chip etc. together with pictorial information part; (5) vehicle mounted guidance decompressing compressed file, synthesizes original image after reading the pictorial information part and actual picture data division mutually marked and shows on display interface.
Described step (2) comprises the following steps: (21) interface images of often opening that often class interface is corresponding is resolved on PC; (22) analysis result is obtained, according to predetermined parsing standard scores from pictorial information part to be marked and real data part to be marked; (23) index of reference marks number one by one picture message part and actual picture data division and is stored to an xml file respectively in order and is undertaken compressing by same pixel and be stored to a bin file.
Described pictorial information part specifically comprises: picture size, position are dark, clear mark and actual pixels data.
Described actual picture data division specifically comprises: the RGB data value of picture.
Described step (4) specifically comprises the following steps: (41) decompress(ion) bin file, obtains the image data part marked; (42) the pictorial information partial index number also corresponding actual picture data division call number obtained marked is obtained, and according to default picture synthetic standards synthesis original image; (43) picture is sent to display device display.
In sum, the present invention has following beneficial effect: (1) can reduce in vehicle mounted guidance storage chip file number, and minimizing vehicle mounted guidance interface images takies the space of storage chip and writes the number of times of storage chip; (2) improve vehicle mounted guidance updating speed, reduce costs, raise the efficiency.
Embodiment
In order to allow those skilled in the art can understand technical scheme of the present invention better, below the invention will be further elaborated.
Present invention is disclosed a kind of vehicle mounted guidance image processing method, comprise the following steps:
(1) vehicle mounted guidance interface images is classified according to different interface; (2) connect PC, undertaken resolving according to default resolution rules by often opening interface images and pictorial information part and actual picture data division are carried out being separated laggard row labels; (3) the pictorial information part marked and actual picture data division are stored to respectively select files; (4) compress the actual picture data division that marked, and it is to be read to be stored to vehicle mounted guidance storage chip etc. together with pictorial information part; (5) vehicle mounted guidance is from storage chip decompressing compressed file, reads the pictorial information part that marked and synthesizes original image after corresponding actual picture data division and show on display interface.
After institute's vehicle mounted guidance interface images is classified by different interface, what every class interface was corresponding often open, and interface images is first resolved on PC, and obtain analysis result, that is: pictorial information part and the real data part of picture is obtained, wherein, real data part comprises: RGB data value, pictorial information part comprises: picture size, position is dark, clear mark, actual pixels data, and according to predetermined parsing standard scores from pictorial information portion to be marked and real data part to be marked, and index of reference number marks picture message part one by one and actual picture data division is also stored to an xml file respectively in order and is undertaken compressing by same pixel and be stored to a bin file.
After being stored to storage chip when selecting files, and when vehicle mounted guidance needs to use, then resolve pictorial information and real data part: decompression bin file, obtain the image data part marked, then the pictorial information partial index number also corresponding actual picture data division call number obtained marked is obtained, then preset picture synthetic standards synthesis original image according to sheet, and this picture is sent on display device shows.
The present embodiment is more excellent embodiment of the present invention, and the part be not described in detail all adopts known mature technology.It should be noted that; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change and are out of shape the protection domain that all should belong to the claim appended by the present invention.
