detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, instead of All embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a schematic flowchart of a method for displaying information according to an embodiment of the present invention. In the embodiment of the present invention, the method includes:

Specifically, the information display method is mainly for displaying corresponding driving information in an information display system in a car. A travel information acquisition unit for acquiring current travel information of the automobile is provided in the automobile. The driving information acquiring unit can acquire the current positioning information of the automobile and the driving environment information around the driving road segment. Accordingly, the driving information acquiring unit can be a global positioning device capable of positioning the automobile, such as GPS or Galileo positioning. The device may also be an image recognition device that acquires current driving environment information of the automobile, such as a binocular camera. The storage unit is further provided with a storage unit that stores map data information, which is data information about the road distribution and the arrangement of the traffic signs. The control unit of the automobile receives the positioning information and the driving environment information from the driving information acquiring unit, and integrates the two kinds of information into the map data information, thereby generating driving information about the current driving state of the automobile, and further, the driving information The driving information can be converted into driving text information in a readable form according to the data information in the positioning information and the inherent text information in the map data information. Correspondingly, the driving text information is mainly about distribution state data of traffic signs or obstacles in the driving section and the surrounding area of the current vehicle, or motion data and driving data of the automobile in the planned driving route, wherein The motion data refers to operation data such as straight-line, turn, or acceleration/deceleration of the automobile, and the driving data refers to data such as the traveling speed or the mileage of the automobile. In fact, in the process of generating the driving text information, the data information collected by the driving information acquiring unit and the map data information are physically superimposed in a usual sense, and the superimposition process does not change the driving information acquiring unit. The original text form of the collected data information. After the control unit converts and generates the driving text information, the driving text information is transmitted to the recognition determining unit.

After receiving the driving text information, the identification determining unit performs character or character string division on the driving text information, and performs two steps of determining the type attribute of the character or the character string. The two steps are implemented based on the partition punctuation database and the text attribute database held by the storage unit, respectively. For example, first, the identification judging unit acquires the demarcation target from the storage unit a point database, the punctuation database includes different kinds of punctuation marks in Chinese and Western formats, and the identification judging unit matches the punctuation marks with the punctuation attachments in the driving text information, and the matching processing mainly refers to the driving The punctuation marks having the broken sentence and/or the ending meaning in the text information are positioned and identified, and finally the identification determining unit realizes the demarcation distinction of the different meaning regions of the driving text information according to the result of the matching processing. Then, the identification judging unit acquires the text attribute database from the storage unit, and the text attribute database includes a correlation evaluation value for evaluating a text character attribute, for example, the related evaluation value may be, but not limited to, a type of text characters. The number of strokes of the text character and the arrangement density of the text characters, wherein the type of the text character refers to a character category attribute such as a Chinese character, a number, an English letter, or a letter case; the number of strokes of the text character is Refers to the number of strokes written per character; the density of the text characters refers to the proportion of the area occupied by the character in the area of the fixed area. The correlation evaluation value can be obtained by learning and analyzing a certain volume of character samples through a preset neural network learning model. The recognition judging unit performs the recognition judgment on the type attribute on the character in the driving text information, and feeds back the result of the recognition judgment back to the control unit.

S102. Perform corresponding display mode processing on the corresponding character or the character string based on the type attribute of the character or the character string.

Specifically, after receiving the recognition judgment result of the driving text information, the control unit acquires display mode data for different character type attributes from the storage unit. The display mode data refers to that the characters of different types of attributes in the driving text information have corresponding different forms of display parameters, and based on the display parameters, the characters can have different display perceptions. The display parameter may be, but not limited to, a color depth value of a character, a stroke thickness value of a character, or a stroke arrangement density value of a character. The control unit transmits the obtained display parameter to the character adjustment unit, where the character adjustment unit is configured to adjust a display form of each character in the driving text information, so that characters of different attribute groups have a specific display form. In this way, the driver can view the driving text information in different display forms.

For example, after receiving the display parameter, the character adjustment unit performs a corresponding search for the character type attribute from the driving text information input by the control unit, and the corresponding search is based on the attribute identification of each character type in the previous step. As a result, the recognition judging process in the previous step performs corresponding calibration on the type attribute of each character and the position information of the character, and counts the position information set of the character of each type attribute in the driving information. The character adjustment unit sets the location information set The position data of the combination is used as a search address index, and the driving text information is sequentially searched or randomly searched, so that the corresponding display form adjustment operation is performed on each character at the same time of searching. In the above manner, the character adjustment unit can implement a controllable display form adjustment operation for each character in the driving text information, and the most intuitive effect of the modulation operation is that the characters of different types of attributes are not clear on the display interface. The same, so that characters with the same type of attributes have a uniform display form to improve the viewing discrimination and display quality of characters of different types of attributes.

S103. Display the corresponding character or character string based on the display priority level of the display mode processing.

Specifically, the character adjustment unit transmits the driving text information after the display driving adjustment to the control unit, and then the control unit acquires a display priority level regarding different types of attribute characters or character strings from the storage unit. The display priority level refers to a character or a character string of different types of attributes in the driving text information having a different display order on the display interface, and the display priority level is preset according to the type attribute of the character or the string, for example, When the character or the character string is a Chinese character, the character or the character string has a first display priority level, and when the character or the character string is a number, the character or the character string has a second display priority level, when the character or the character When the string is English, the character or string has a third display priority level. A person skilled in the art can set the display level of a character or a character string according to actual needs, and the above-mentioned example case only belongs to one of the preferred modes.

Further, after the control unit divides the display priority level of the characters or character strings of different types of attributes, the control unit can also set the corresponding display duration based on the display priority level corresponding to the character or the character string. Correspondingly, a character or a character string having a higher display priority level is set to have a longer display duration. In fact, if a character or a character string has a higher display priority level, it indicates that the text information content displayed by the character or the character string has a higher meaning for controlling the driving state of the car, by using the above-mentioned pair of different characters or strings. The setting of the display duration ensures that the driver does not miss the driving text information content with a higher display priority level during driving.

As can be seen from the above embodiment, the information display method converts the travel information into corresponding driving text information by acquiring driving information of the automobile during driving, and then performs character and string type attributes on the driving text information. Identifying and judging, thereby achieving initial recognition of the driving text information; in addition, the method can also identify the area based on the type attribute of the character and the character string Dividing, performing specific display mode processing on corresponding characters and character strings, the display mode processing is such that characters and character strings of different types of attributes have different display forms on the display interface, which enables the driver to display directly and quickly Characters and strings of different types of attributes are respectively displayed on the interface; finally, the method can also display characters and strings of different types of attributes based on the preset display priority level, which can improve display uniformity and display quality of driving information. In order to ensure the display integrity of driving information.
