摘　　要：该文提出一种基于运动物体DBT(detect before track)背景消除法识别红外小目标,并将其应用于空中鼠标中。实验主要经过色彩空间转换、阈值分割、图像开运算、连通分析后进行目标识别,并通过摄像头标定获取识别目标在视野中的相对位置。通过单片机以及2.4G通信模块,将除位置信息以外的控制信息传递到电脑。以电脑进行位置运算,单片机进行控制。实验结果表明,该方案识别的目标精度较高,价格低廉,具有一定应用前景。In this paper, we have proposed one method to identify the infrared small target based on moving object DBT(detect before track) background elimination, and applied it to the air mouse. The target is recognized mainly through the steps below: color space conversion, threshold segmentation, image open operation, connection area analysis, and then identify the target relative position in the field of vision captured.By MCU(micro-controller unit) and 2.4G communication module, the control information will be transmitted to the computer. Recognized the position by computer and control by the MCU. The result shows that the proposed scheme has higher target accuracy, lower price and a certain application prospect.
