Abstract本发明涉及一种复杂背景下图像中鲁棒的编码点的精确识别与定位方法,包括以下步骤:在被测物体表面均匀地布置多个不同的编码点和非编码点;利用摄像头或数码相机采集图像;利用上述采集的图像提取图像中编码点的中心椭圆;根据中心椭圆得到的该中心椭圆的编码带信息,并利用编码带对中心椭圆进行参数修正;根据修正后的中心椭圆参数对编码点进行解码并输出各编码点的ID号。本发明鲁棒性强,精确度高,直接嵌入到三维数字测量软件的数据预处理系统中,为后续的三维重建提供可靠的输入数据。
Other AbstractThe invention relates to a precise identification and position method of robust coding points in an image under complex background, comprising the following steps: evenly arranging a plurality of different coding points and non-coding points on the surface of the objects to be detected utilizing a camera or a digital camera to acquire images utilizing the acquired images to extract the central oval of coding points in the images obtaining coding strip information of the central oval according to the central oval, and utilizing the coding strip to modify parameters and decoding the coding points according to modified parameters of the central oval and outputting the ID number of each coding point. The invention has strong robust property and high precision, and can be directly embedded into the data preprocessing system of three-dimensional digital measurement software, thereby providing reliable input data for successive three-dimensional reconstruction.
