摘　　要：实现了在多障碍物环境下的无线传感器网络中的图像传输。传统的图像传输均采用有线的方式。随着无线通信技术的发展,它也被用来传输图像。但是这些最初的无线传输技术只能够点对点传输、对硬件要求高、成本昂贵。在无线传感器发展成熟后,我们考虑到无线传感器网络具有自组网、对硬件要求低、成本低廉等特点,采用了无线传感器网络来传输图像。在文中所描述的图像传输系统中,首先用摄像头对图像进行采集,再用无线传感器网络来对采集到的图像进行传输,最后通过网关及计算机终端对传输的图像进行接收。实验结果表明:该系统具有组网简单,不需要特殊的设备就能够在环境恶劣的场合(如矿井下)实现图像传输。This paper presents on image transmission based on wireless sensor networks in a multi-barrier environment.The traditional wired technology is usually adopted for image transmission.With its fast development,the wireless communication technology is also used for image transmission.However,this elementary wireless transmission technology is used only for point-to-point transmission,and has a high requirement for hardware devices and thus is rather expensive.With maturity of this technology and for its features of Ad Hoc network,low hardware requirement and low cost the wireless sensor network is used to transmit images.The image transmission system proposed in this paper,first uses the camera for image capture,and then transimits the captured image,and finally receives the image by the gateway and the computer terminals.The experimental results show that the system is simple in networking and requires no special equipment,and could realize the image transmission in advese environment（such as an underground mine）.
