In 3D scanning system based on line laser, a CCD video camera is used for taking pictures of an object, after black-white processing artificial neural networks transfer pixel coordinates that represent outline of the body to world coordinates.

• 在线状激光三维扫描技术中,用面阵 CCD 摄像机摄取图像,用前馈型人工神经网络对二值化后的图像进行变换,可直接得到物体轮廓线的二维坐标;
