    摘要:

    針對現(xiàn)有農(nóng)業(yè)圖像采集設(shè)備分辨率低且無法調(diào)節(jié)圖像效果的現(xiàn)狀,提出一種基于ARM,、CMOS圖像傳感器和嵌入式Linux操作系統(tǒng)的高分辨農(nóng)業(yè)圖像采集節(jié)點(diǎn)的設(shè)計方案。設(shè)計了采集節(jié)點(diǎn)的硬、軟件體系結(jié)構(gòu),實(shí)現(xiàn)了圖像傳感器驅(qū)動控制,可進(jìn)行5種白平衡,、7級亮度、5級對比度、5級飽和度的圖像采集效果控制,。試驗(yàn)結(jié)果表明,本采集節(jié)點(diǎn)能進(jìn)行2 048像素×1 536像素的圖像采集,,并能較好地控制圖像的白平衡,、亮度、對比度,、飽和度等像素效果,。所設(shè)計節(jié)點(diǎn)具有體積小、成本較低等特點(diǎn),可廣泛應(yīng)用于農(nóng)業(yè)圖像采集,。

    Abstract:

    Since the current agricultural image sensor was low resolution and lack of adjustable control function, a high-resolution agricultural image capture node was designed based on ARM, OV hardware platform, and embedded Linux operating system. Both the hardware and software architecture of the image capture node were designed, the node could be controlled easily. It had better control function than traditional image sensor, which had five kinds of white balance control mode, seven levels of brightness, five levels of contrast and five levels of contrast and five levels of saturation effects. It could satisfy the needs to control image acquisition, and provided a convenient remote dynamic application in different scenarios to adjust image capture effects. Experimental results showed that the node could capture the 2 048 pixels×1 536 pixels of image. It also had the advantages of small volume and low cost. This node could be widely used in agricultural image capture, particularly suitable for wireless image sensor networks, crop images and video in real time monitoring.
