Description
Technical Field
The invention relates to an optimized display method based on an S52 standard chart water depth symbol.
Background
In actual sailing, the accurate water depth value in the sea chart is sailing safety protection sailing. The water depth values of all target points in the sea area are efficiently and accurately displayed in the electronic chart, and a very important basis can be provided for the captain to know the surrounding sea area conditions in a macroscopic manner. The current implementation modes of the S52 standard are different, the description form of the symbol is changed, and SVG vector description language is used for optimizing symbol display; some optimize symbol display by creating a database; however, these schemes are another implementation manner of the conventional technical scheme, and basically, the symbols in the S52 standard and the optimized symbols still maintain a one-to-one correspondence. The problems that the deep water symbols in the sea are difficult to maintain and easy to make mistakes and the display efficiency is low cannot be thoroughly solved.
The S52 standard is provided with a series of coordinate points marked as symbol drawing paths, each symbol is provided with a respective symbol drawing path, and the symbol drawing paths are sequentially connected to be drawn into each individual number from 0 to 9, and the number is marked as a decimal digit symbol of the water depth value. The symbol names related to the water depth point are SY (SOUNDG 00) to SY (SOUNDG 59) 60 symbol names, SY (SOUNDS 00) to SY (SOUNDS 59) 60 symbol names, and 120 symbol names in total. Wherein SY indicates that the symbol is a dot symbol; "SOUNDG01" means the body name of a symbol, necessarily 8 characters; the last 1 indicates that the effect of the symbol display is the number 1; the penultimate number is associated with the position of the symbol pivot point and corresponds to the decimal place of the water depth value as shown in fig. 1.
The traditional technical scheme comprises the following steps: and acquiring the value of the water depth to be displayed. And separating to obtain each decimal number in the water depth value. For example, if the value is 95.6, three numbers of 9,5 and 6 are separated. And searching corresponding three symbols according to the three numbers 9,5 and 6. 9 is the number on ten digits, and the sign representing the number 9 on ten digits is required to be searched according to the last-last number of the sign; similarly, find the sign representing the bit number 5, the sign of the decimal number 6; thus, 3 water depth value decimal place symbols are obtained. And drawing the obtained 3 symbols at the same point according to the sequence to obtain a complete water depth value symbol.
However, for the traditional technical scheme, 10 symbols of 0-9 are generated for numbers on all decimal digits, the total number of symbols to be maintained is up to 120, the symbols are not easy to maintain and expand, the probability of errors is increased due to the increase of the number, and the difficulty of positioning error symbols is increased. When displaying the water depth value symbol, all corresponding water depth value decimal place symbols need to be searched from 120 symbols, and each decimal place needs to be searched once, so that the searching efficiency is too low. Moreover, in practice, each decimal digit is a single water depth value decimal digit symbol, and the combination is a complete water depth value symbol. If a single water depth value decimal place symbol is problematic, the water depth value cannot be found accurately, so that the displayed water depth value is problematic, and navigation safety is compromised.

If the traditional scheme needs to expand the water depth value symbol, for example, the symbol color is simply changed, and 60 symbols are added for each color; not only the difficulty of expansion is increased and mistakes are easy to occur, but also the maintenance difficulty is increased; meanwhile, the method brings trouble to subsequent testing work.
When the traditional scheme displays the water depth value sign, the sign of each decimal digit in the water depth value needs to be drawn, and if the water depth value is hundred digits, 3 or even 4 signs are needed to completely display the water depth value. The invention only needs to search the corresponding symbol from the second set, obtain the corresponding symbol drawing path, then draw the symbol in real time, only need to display one symbol. The efficiency of displaying a single complete water depth value symbol is improved.
The traditional scheme is to search each symbol in 120 symbols, and the invention only needs to search in 10 symbols in the second set, so that the searching efficiency is greatly improved. Since the number of water depth values in the sea chart is hundreds to thousands, the improvement in efficiency reflected in the entire sea chart system is very significant here even though the magnitude of the improvement is small.
The invention simplifies 120 symbols into 10 symbols, draws the water depth value symbol in real time according to the name of the symbol, and the obtained water depth value symbol is an integral symbol instead of a combined symbol in which a plurality of symbols are simply displayed on the same position.

Example 1
As shown in fig. 5, the optimized display method based on the S52 standard chart water depth symbol comprises the following steps:
a1, acquiring a second set according to a preset first set.
The first set includes: 120 water depth value symbols.
Each water depth value symbol has a symbol name and a drawing path of an S52 chart display standard corresponding to the symbol.
The symbol name of the water depth value symbol has 12 characters; and the 11 th character from left to right in the symbol name of the water depth value symbol is any number from 0 to 9.
The second set in this embodiment includes: any one of the 11 th character from left to right in the symbol names of the water depth value symbols is 0, any one of the 11 th character from left to right in the symbol names of the water depth value symbols is 1, any one of the 11 th character from left to right in the symbol names of the water depth value symbols is 2, any one of the 11 th character from left to right in the symbol names of the water depth value symbols is 3, any one of the 11 th character from left to right in the symbol names of the water depth value symbols is 4, any one of the 11 th character from left to right in the symbol names of the water depth value symbols is 5, any one of the 11 th character from left to right in the symbol names of the water depth value symbols is 6, any one of the 11 th character from left to right in the symbol names of the water depth value symbols is 7, and any one of the 11 th character from left to right in the symbol names of the water depth value symbols is 9.
In the specific application of the present embodiment, the second set is acquired by taking the total of 120 symbol names among 60 symbol names SY (soung 00) to SY (soung 59) (using the first color) and 60 symbol names SY (soung 00) to SY (soung 59) (using the second color). The symbol SY (sountgxx) is identical to the symbol SY (sountsxx) except for the color, including the location of the pivot point. As shown in fig. 3, fig. 3 is a symbol SY (soungg 00), and fig. 4 is a symbol SY (soungs 00).
In this embodiment, there are 6 sets of 0 to 9 water depth value decimal place symbols, 10 for each set, of 60 symbols SY (soungg 00) to SY (soungg 59).
In this example, there are also 6 sets of 0 to 9 water depth decimal place symbols, 10 for each set, of 60 symbols SY (SOUNDS 00) to SY (SOUNDS 59).
For example, the three numbers SY (SOUNDS 20), SY (SOUNDS 10) and SY (SOUNDS 50) are identical, except for the location of the pivot point. Thus, 10 symbols in the second set can be found out of 60 symbols SY (SOUNDG 00) to SY (SOUNDG 59) and 60 symbols SY (SOUNDS 00) to SY (SOUNDS 59) for a total of 120 symbols.
The 10 symbols in the second set may be 10 symbols of SY (SOUNDS 00) to SY (SOUNDS 09), 10 symbols of SY (SOUNDG 00) to SY (SOUNDG 09), or 10 symbols of SY (SOUNDS 00), SY (SOUNDG 51), SY (SOUNDG 32), SY (SOUNDS 03), SY (SOUNDG 44), SY (SOUNDS 15), SY (SOUNDS 16), SY (SOUNDG 37), SY (SOUNDG 28), SY (SOUNDS 59). The second set may be provided that the 60 symbol names SY (soungg 00) to SY (soungg 59) and the 60 symbol names SY (soungs 00) to SY (soungs 59) are the last digits of any 10 symbol names among the total 120 symbol names, that is, the 11 th character in the symbol names is 10 symbols of 0,1,2,3,4,5,6,7,8, 9.
A2, acquiring a plurality of water depth values to be displayed, and determining a first color or a second color corresponding to the water depth values to be displayed based on the water depth values to be displayed.
A3, determining the symbol name of the water depth value symbol corresponding to the water depth value to be displayed in the second set based on the water depth value to be displayed.
The step A3 in this embodiment includes:
and A3-1, separating the water depth value to be displayed, and obtaining the number in each decimal place in the water depth value to be displayed.
In this embodiment, if the water depth values to be displayed are 158 and 95.6, 158 is separated into 1,5,8. 95.6 was separated into 9,5,6.
A3-2, determining the symbol name of the water depth value symbol corresponding to the number in each decimal place in the water depth value to be displayed in the second set.
Wherein the symbol name of the water depth value symbol corresponding to the number of each decimal digit in the water depth value to be displayed in the second set is: the 11 th character in the first water depth value symbol in the second set is the same symbol name of the water depth value symbol as the number in the decimal place in the water depth value to be displayed.
For example, if the second set is 10 symbols SY (SOUNDS 00) to SY (SOUNDS 09), if the water depth value to be displayed is 158, the symbol names corresponding to the water depth value 158 to be displayed in the second set are SY (SOUNDS 01), SY (SOUNDS 05), SY (SOUNDS 08).
A4, determining a drawing path of the water depth value symbol corresponding to the water depth value to be displayed in a preset S52 standard symbol drawing path based on the symbol name of the water depth value symbol corresponding to the water depth value to be displayed;
a5, drawing the symbols of the water depth values to be displayed by adopting a drawing path of the water depth value symbol corresponding to the water depth value to be displayed, a preset interval value and/or a preset height value, a first color and/or a second color. As shown in fig. 2, the display effect of the water depth value in the chart.
The symbol of the water depth value to be displayed has a first color or a second color corresponding to the water depth value to be displayed.
In a specific application of this embodiment, if the water depth value to be displayed is an integer less than or equal to 9, a drawing path of the water depth value symbol corresponding to the integer and a first color or a second color corresponding to the water depth value are adopted to draw the symbol of the water depth value to be displayed.
For example, in the present embodiment, when the second set is SY (SOUNDS 00) to SY (SOUNDS 09), if the water depth value to be displayed is 8, a symbol drawing path of SY (SOUNDS 08) is used to draw a symbol of the water depth value of 8.
In a specific application of this embodiment, if the water depth value to be displayed is an integer greater than 9, drawing paths of a plurality of water depth value symbols corresponding to the water depth value to be displayed, preset interval values, and first color or second color corresponding to the water depth value to be displayed are adopted to draw the symbols of the water depth value to be displayed.
For example, when the second set is SY (sounfs 00) to SY (sounfs 09) in the present embodiment, if the water depth value to be displayed is 158, the 3 symbol drawing paths of SY (sounfs 01), SY (sounfs 05), SY (sounfs 08) are adopted, and 1 symbol with the water depth value of 158 is drawn.
Wherein the drawing path of 1 and the drawing path of 5 in 1 symbol of the water depth value 158 are spaced 1 millimeter apart, and the drawing path of 5 and the drawing path of 8 are spaced 1 millimeter apart.
In a specific application of this embodiment, if the water depth value to be displayed is less than 10 and has a decimal digit, drawing a water depth value symbol to be displayed by adopting a drawing path corresponding to the decimal digit of the water depth value to be displayed, a drawing path corresponding to the decimal digit, a preset interval value and a preset height value, and a first color or a second color corresponding to the water depth value to be displayed.

And the drawing path corresponding to the decimal digit of the water depth value have preset height values.
For example, when the second set is SY (sounfs 00) to SY (sounfs 09) in the present embodiment, if the water depth value to be displayed is 5.6, SY (sounfs 05), SY (sounfs 06) is used, and the 2 symbols are drawn along the drawing path, and 1 symbol with the water depth value of 5.6 is drawn.
Wherein the drawing path of 5 and the drawing path of 6 in 1 symbol of the water depth value 5.6 are laterally spaced by 1 millimeter, and the drawing path of 5 is higher than the drawing path of 6 by 1.25 millimeters.
In a specific application of this embodiment, if the water depth value to be displayed is greater than or equal to 10 and has a decimal number, a drawing path of a plurality of water depth value symbols on an integer corresponding to the water depth value to be displayed, a drawing path of a water depth value symbol on a decimal corresponding to the water depth value to be displayed, a preset interval value and a preset height value, and a first color or a second color corresponding to the water depth value to be displayed are adopted to determine the symbol of the water depth value to be displayed.
And the interval values of the preset transverse intervals are arranged among the drawing paths of the water depth value symbols corresponding to the numbers of the water depth value integer digits to be displayed.
And a preset transverse interval value is arranged between the drawing path of the water depth value symbol corresponding to the number on the position of the water depth value to be displayed and the drawing path of the water depth value symbol corresponding to the number on the decimal of the water depth value to be displayed.
And a preset height value is arranged between the drawing path of the water depth value symbol corresponding to the number on the position of the water depth value to be displayed and the drawing path of the water depth value symbol corresponding to the number on the decimal of the water depth value to be displayed.
For example, when the second set is SY (sounf 00) to SY (sounf 09) in the present embodiment, if the water depth value to be displayed is 95.6, SY (sounf 09), SY (sounf 05), SY (sounf 06) are used, and the 3 symbols are drawn to draw 1 symbol of the water depth value of 95.6.
Wherein, the drawing path of 9 and the drawing path of 5 in 1 symbol of the water depth value of 95.6 are laterally spaced by 1 millimeter, the drawing path of 5 and the drawing path of 9 are the same in height, the drawing path of 5 and the drawing path of 6 are laterally spaced by 1 millimeter, and the drawing path of 5 is higher than the drawing path of 6 by 1.25 millimeter.
In this embodiment, 120 symbols are simplified into 10 symbols, and the completed water depth value symbol is drawn in real time according to the name of the symbol, where the water depth value symbol is actually one symbol; instead of looking up a single symbol per decimal place from 120 symbols, the combination is displayed as a water depth value symbol, which is actually a plurality of symbols.
In the embodiment, only the drawing path of the symbol is focused, only coordinate data is saved, and each water depth value symbol is generated by real-time calculation; instead of focusing on the symbol itself, the display effect of the symbol is not preserved.
