[0002] With the development of automobile intelligence, the in-vehicle display screen has become an important part of the human-computer interaction in the vehicle intelligent cockpit, and its interface design directly affects the driver's experience and safety. The in-vehicle display screen interface not only needs to have good aesthetics and ease of use, but also needs to meet the special needs of the driving environment, such as fast information recognition, low interference and high readability.

[0003] Chinese characters are the main form of text presentation in Chinese user interfaces. Their text layout design directly affects the user's visual experience and ease of operation, and the design of character spacing and line spacing is an important factor. However, the boundaries of Chinese characters are usually difficult to distinguish. The current measurement method for the character spacing of Chinese characters on vehicle-mounted display screens is relatively cumbersome. The character spacing and line spacing measurement methods in the field mainly rely on the annotation function of the design software or manual estimation, which lacks automation and objectivity and the measurement accuracy is not enough. Therefore, there is an urgent need for an efficient and accurate character spacing measurement method to optimize the layout design of vehicle-mounted display screens. Summary of the invention

[0004] The purpose of the present invention is to provide an efficient and accurate method for measuring the spacing between Chinese characters and the line spacing on a vehicle-mounted display screen. The method uses the ADB system of the vehicle computer to obtain a screenshot, and accurately measures the character spacing by searching for the style of specific text in the bar and its coordinate calibration method, thereby providing data support for the scientific design of the spacing between Chinese characters and the line spacing on the vehicle-mounted display screen, and providing technical guarantee for optimizing user experience and improving driving safety.

[0068] In order to more clearly illustrate the specific implementation mode of the present invention, an embodiment is provided below:

[0069] In order to study the impact of the readability of the Chinese character spacing and line spacing on the vehicle display screen on safe driving, it is necessary to measure the Chinese character spacing and line spacing displayed on the vehicle display screen (such as Figure 3 ).

[0070] Open the on-board display of the vehicle to be tested Figure 3The page is captured using the ADB system and saved as "Text Screenshot".

[0071] Furthermore, record the first two characters "When the vehicle" and "Suspension" at the beginning of the first and second lines of the text part of the page.

[0072] Furthermore, enter the measurement reference Chinese characters "Guo Guo Wei" and the measurement target text "When the vehicle" in the Bluetooth search function of the in-vehicle display, and then capture a screenshot using the ADB system and save it as "Input Reference Text 1" (as Figure 4 ).

[0073] Furthermore, enter the measurement reference Chinese characters "Guo Guo Wei" and the measurement target text "Suspension" in the Bluetooth search function of the in-vehicle display, and then capture a screenshot using the ADB system and save it as "Input Reference Text 2" (as Figure 5 ).

[0074] Furthermore, obtain the boundary information of "When the vehicle" and "Suspension" in the "Text Screenshot" through the software in the device, and extract the coordinate values of the four extreme positions: the leftmost, topmost, bottommost, and rightmost.

[0075] Furthermore, obtain the text boundary information of "When the vehicle" in the "Input Reference Text 1" through the software, and scale the coordinate values of its four extreme positions: the leftmost, topmost, bottommost, and rightmost, proportionally to be consistent with the coordinate values of "When the vehicle" in the "Text Screenshot".

[0076] Furthermore, obtain the text boundary information of "Suspension" in the "Input Reference Text 2" through the software, and scale the coordinate values of its four extreme positions: the leftmost, topmost, bottommost, and rightmost, proportionally to be consistent with the coordinate values of "Suspension" in the "Text Screenshot".

[0077] Furthermore, measure the coordinate values of the four vertices of the three characters "Guo Guo Wei" in the scaled "Input Reference Text 1" through the software (as Figure 6 ), and calculate the character spacing between adjacent two Chinese characters respectively. Specifically, take the x coordinate value of the left vertex of the second "Guo" minus the x coordinate value of the right vertex of the first "Guo", that is, the character spacing in the "Text Screenshot" is 6 pixels, and then repeat to calculate the x coordinate difference between "Wei" and the second "Guo" which is also 6 pixels, and the target measured character spacing is verified. Therefore Figure 3 The character spacing of the target paragraph in the page is 6 pixels.

[0078] Furthermore, measure the coordinate values of the four vertices of the three characters "Guo Guo Wei" in the scaled "Input Reference Text 1" and "Input Reference Text 2" through the software (as Figure 6), and calculate the line spacing between two adjacent reference Chinese characters above and below respectively. Specifically, subtract the y-coordinate value of the lower left vertex of the first "国" in "Input Reference Text 1" from the y-coordinate value of the upper left vertex of the first "国" in "Input Reference Text 2", that is, the line spacing in the "Text Screenshot" is obtained as 16 pixels. Then repeat the calculation, and the y-coordinate difference of the second measured reference Chinese character "国" corresponding to two adjacent lines is 16 pixels, and the target measured line spacing is verified. Therefore Figure 3 The line spacing of the target paragraph on the page is 16 pixels

[0079] Furthermore, given the known resolution of the in-vehicle display screen as 2560×1440 and the screen size as 15 inches, the character spacing in the "Text Screenshot" is obtained as 0.78 mm and the line spacing is 2.08 mm.

[0080] The above steps are all implemented by the in-vehicle display screen Chinese character spacing and line spacing measurement device.
