摘　　要：针对目前3D相机中出现的图像数据易丢失、左右图像同步难等问题,提出一种可精确采集左右格式立体对图像的仿生3D传感器实现方法,可为仿生3D传感器的光路系统的检验及目标物三维重建提供精确三维坐标信息。为更好协调3D传感器在光信号处理中的点像素同步,采用现场可编程门阵列处理双OV3640图像传感器各信号,初始化后在像素时钟的准确控制下采集图像数据并完成输出图像格式转换、缓存、左右格式立体对图像拼接及输出显示验证。结果表明,3D传感器工作可靠、集成度高、体积小,可精确采集左右格式立体对图像。In order to solve current problems of 3D camera like too small central figure in the pictures, close shot and distant view are serious mis- match that caused by lens＇ and sensors＇ not meeting the requirements of bionic vision, a kind of method is put forward that can collect stereo pair for- mat image with biomimetic 3D sensor precisely which can provide a good video source for Naked - eye 3D display equipment. To better coordinate the 3D sensor pixel synchronization in optical signal processing, field programmable gate array is used to process double OV3640 image sensor＇s signal, image data is collected and the format conversion, cache, stereo pair format images＇ mosaic of output image are fufilled after initialization, and output display is validated under the accurate control of the pixel clock . The results show that the 3D sensor is reliable, high integration and small size, which can collect left and right format stereo pair images accurately.
