Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly. The examples are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The automatic test method of the cockpit display system based on image recognition shown in this embodiment divides the display screen into the smallest recognizable units by analyzing the model of the cockpit display system, and realizes automatic testing through image recognition of the smallest recognizable units. It mainly includes three links: cockpit display system model analysis, test case design and runtime automatic test.

[0020] Specific steps are as follows:

[0021] Step 1: Obtain the display model o...

Abstract

The invention discloses an image-recognition-based automatic test method for a cockpit display system. Analyses are carried out on a non-ARINC661 standard display picture model and an ARINC661 standard display picture model to obtain minimum identifiable units of display picture sand attributes of all units; and with the image recognition technology, all minimum identifiable units are identified and tested. According to the invention, the automatic test of the cockpit display system can be realized based on construction of the minimum identifiable units; the traditional status of relying on the manual test is changed; and thus the efficiency and accuracy of the cockpit display system test are improved effectively. The image-recognition-based automatic test method and system have the greatpromotion and application values.

Description

technical field [0001] The invention belongs to the technical field of testing and relates to a cockpit display system, in particular to an image recognition-based automatic test method for a cockpit display system. Background technique [0002] With the development of avionics, the requirements for human-computer interaction continue to increase, the degree of integration of the cockpit display system continues to increase, the structure becomes more and more complex, and the integrated display with rich functions replaces the traditional display instrument. The display screen of the integrated display includes both the display screen conforming to the ARINC661 standard and the non-661 format display screen, and the display screen has a high degree of integration, involving all other systems on the aircraft. [0003] Due to the need to judge the display screen, the current test of the cockpit display system is completely carried out manually. After the test engineer spends ...
