Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of display control processor testing, and particularly relates to a display control processor testing method and system for simulating trackball operation. BACKGROUND

[0002] The trackball is one of the commonly used human-computer interaction control devices in the cockpit of an airplane, and mainly provides a control function for a cursor on a display, which is similar to a "mouse" in the cockpit of an airplane.

[0003] The trackball has a style as shown in the figure Figure 1 , wherein A is a selection and confirmation button, B is a scroll wheel, which provides a page up and down operation for a picture where a cursor is located, C is a scroll ball, which provides a moving operation for the cursor in horizontal and vertical directions, and D is a "switch" button, which provides a control function for sequentially switching a display area where the cursor is located.

[0004] The trackball is connected to an airborne display control processor through an airborne bus, and the trackball realizes a control function for the system by sending a bus message to the display control processor (embedded display control software), and the content of the sent bus message usually includes a scroll wheel change amount, a scroll ball X displacement, a scroll ball Y displacement, and a button word, wherein the vector formed by the combination of the X displacement and the Y displacement represents a moving speed and direction of the cursor in a display picture.

[0005] In order to improve the research and development efficiency and quality of an airplane system, an automatic test technical means is usually adopted, and the automatic test of the display control processor of a display control system is more complex, and usually involves automatic identification and determination of a display picture and simulation of a pilot operation, for which, a current airplane system automatic test device based on image recognition is constructed, which can support automatic test of the display control system based on image recognition, but cannot simulate the control operation of the trackball, and when a trackball related human-computer interaction test case is executed, manual operation is necessary, which breaks the automatic test chain, and leads to low test efficiency of the display control processor, and therefore, the application is proposed.

[0069] Soft button interaction area position coordinate acquisition step: according to the operation demand, the display picture is marked, and the position coordinates of the interaction area of the corresponding soft button in the display picture are acquired.

[0070] The marked display picture includes defining the operation instruction name and acquiring the rectangular interaction area of the corresponding soft button.

[0071] The position coordinates of the interaction area of the corresponding soft button in the display picture are acquired, specifically the position coordinates (Xmin, Ymin), (Xmax, Ymax) of the left lower and right upper vertices of the soft button are acquired.

[0072] Cursor position coordinate acquisition step: the position coordinates (Xcursor, Ycursor) of the cursor in the display picture are acquired.

[0073] The position coordinates (Xcursor, Ycursor) of the cursor in the display picture can be obtained through image recognition.

[0074] The cursor moving direction is calculated according to the position coordinates of the interactive area of the soft button in the display picture and the position coordinates of the cursor.

[0075] X' = (Xmin+Xmax) / 2-Xcursor;

[0076] Y' = (Ymin+Ymax) / 2-Ycursor;

[0077] Wherein:

[0078] (X', Y') is the vector representation of the moving direction of the cursor.

[0079] The X-Y direction displacement of the trackball is calculated according to the moving direction of the cursor.

[0082] Wherein:

[0083] S is the reference value of the analog quantity of the trackball controlling the moving of the cursor.

The display and control processor test system for simulating trackball operations according to claim 11, wherein In the trackball movement simulation module, bus messages corresponding to the trackball movement are continuously sent to the display and control processor, specifically the displacements of the calculated trackball in the X-Y directions.

13. The display and control processor test system for simulating trackball operations according to claim 12, wherein In the cursor position coordinate real-time acquisition and judgment module, the position coordinates (X cursor, Y cursor) of the cursor in the display screen can be specifically acquired in real time through image recognition.

14. The display and control processor test system for simulating trackball operations according to claim 13, wherein In the cursor position coordinate real-time acquisition and judgment module, if Xmin < X cursor < Xmax and Ymin < Y cursor < Ymax, it is determined that the cursor enters the interaction area of the soft button.
