Computer vision-based programming practice assessment system and method

Abstract

The present invention proposes a computer vision-based programming practice assessment system and method, including: an image acquisition module, a cursor detection module, a text detection module, and an evaluation module; the image acquisition module is used to collect computer screen images for programming practice assessment The cursor detection module is used to judge the behavior type according to the change of the cursor movement in the computer screen; the text detection module is used to locate the current line code position, and obtains the corresponding text position and text width; the evaluation module is used for Static parameters and dynamic parameters are extracted and evaluated from the cursor detection module and the text detection module; the static parameters include program text rules; the dynamic parameters include typing speed, number of deleted and modified characters, and pause time ratio parameters. It can automatically process and analyze the process of programming practice assessment by computer.

Description

technical field [0001] The invention belongs to the technical field of computer vision and teaching aids, and in particular relates to a computer vision-based programming practice assessment system and method. Background technique [0002] In computer software-related teaching and assessment, if only relying on the final result of the code to judge the student's score, it cannot fully evaluate the student's level, and there are still many problems. For example, there are codes that achieve the same function, but the code is completed. There is a large gap in scores, and it is difficult to judge the true level of students only relying on a single final score. And at present, it is often only through manual marking and evaluation by teachers, which is time-consuming and laborious, and the objectivity is also insufficient. Contents of the invention [0003] Aiming at the gaps in the prior art, the present invention proposes a computer vision-based programming practice assess...
