摘要
为提取清晰、完整的光照不均图像轮廓,设计嵌入式技术的光照不均图像边缘检测系统。图像采集模块使用CMOS图像传感器采集光照不均图像,运用通信接口模块,将采集的图像传输到内嵌EP9315处理器的嵌入式模块,利用基于Canny算子的光照不均图像边缘检测方法,提取光照不均图像的完整轮廓,并通过HDMI显示模块,将实时光照不均图像和处理后边缘图像展示给用户,实现光照不均图像边缘检测。实验结果表明:该系统将CMOS图像传感器的帧频设置为300 fps,可采集到质量较高的光照不均图像;该系统的光照不均图像平滑处理和边缘检测能力均较为理想,且对于光线极差的夜间光照不均图像也能呈现出较优良的边缘检测效果。
In order to extract the clear and complete contour of uneven illumination image,an edge detection system of uneven illumination image based on embedded technology is designed.The image acquisition module uses the CMOS image sensor to collect the uneven illumination image,uses the communication interface module to transmit the collected image to the embedded module embedded with Ep9315 processor,uses the uneven illumination image edge detection method based on Canny operator to extract the complete contour of the uneven illumination image,and displays the real-time uneven illumination image and the processed edge image to the user through the HDMI display module,Realize the edge detection of uneven illumination image.Experimental results show that when the frame rate of CMOS image sensor is set to 300 fps,high quality illumination uneven images can be acquired.The system has better smoothing and edge detection ability for uneven light images,and also has better edge detection effect for uneven light images at night.
