基于單片機(jī)圖像采集裝置的設(shè)計

摘    要
在現(xiàn)代工業(yè)自動化生產(chǎn)中，涉及到各種各樣的檢驗、生產(chǎn)監(jiān)視及零件識別應(yīng)用。通常人眼無法連續(xù)、穩(wěn)定地完成這些帶有重復(fù)性和智能型的工作，其他傳感器也難有用武之地。由此開始用攝像頭來采集圖像，經(jīng)計算機(jī)進(jìn)行處理后，得到想要的信息，從而產(chǎn)生了視覺傳感器。
本設(shè)計以Freescale公司的16位單片機(jī)MC9S12DG128為核心，采用以O(shè)V6620作為圖像傳感器的數(shù)字?jǐn)z像頭，通過RS232接口將采集到的圖像數(shù)據(jù)上傳至上位機(jī)，在上位機(jī)上進(jìn)行圖像的處理、存儲及識別。本設(shè)計完成了單片機(jī)核心模塊的設(shè)計、數(shù)字傳感器電路的設(shè)計、RS232串行通信接口電路的設(shè)計；在Codewarior開發(fā)環(huán)境下，利用C語言編程實現(xiàn)了數(shù)字圖像的采集、圖像信息的上傳等功能。最終實現(xiàn)了對圖像的數(shù)字化采集并完成了采集裝置與上位PC機(jī)的通信功能。

ABSTRACT
In the modern industrial automation, sensors involve a variety of testing, production monitoring and parts identification applications. Typically, the human’s eyes can not be continuous, stable and complete these with intelligent repetitive work. And other sensors are also difficult to have its uses. Thus people began to use cameras to capture images processed by computer to obtain the desired information, resulting in a visual sensor.
The design is completed the design of the microcontroller core module, digital sensor circuit, RS232 serial communication interface circuit; In Codewarior development environment, the system uses the C language programming of the digital image acquisition, the information of image uploaded and so on. Finally, the design realized the digital image acquisition and completed communication between the acquisition device and the host PC.

Key words： image acquisition; microcontroller; Digital camera
