摘要
以棒材计数系统中计数显示系统为例,介绍了一种以TMS320DM6437为控制内核的OSD显示技术。该方案将采集到的棒材图像与棒材计数结果文字字符完成叠加,并通过VGA显示器实时显示。本方案在实际项目的系统中工作稳定,字符显示位置可灵活修改,能方便应用于实时显示。
This article takes a counting display system for steel bar as the example to illustrate the on screen display technology which is based on TMS320DM6437. The program collects images for bar and rod to complete count text characters superimposed. Further more, the results are displayed by the VGA display in real-time. Consequently, this design in actual project works stably, and can flexibly modify character display position and display in real-time can be achieved.
