在计算机视觉的许多领域中，校准线扫描器的响应函数是非常重要的。提出了一种减少像素响应函数不等价性的方法。与目前最先进的方法相反，我们的方法使用线性光源，通常连接到线扫描仪进行像素级校准。我们定义了线性光源的辐射强度函数，并将其拟合到捕获的图像中以校准响应函数。我们将该方法应用于线感相机，在扫描时去除条纹噪声，实验结果表明系统中的噪声显著降低。
Calibrating the response function of a line scanner is very important in many fields of computer vision. We propose a method to reduce nonequivalence present in response functions of pixels. Contrary to current state-of-the-art methods our method uses a linear light source which is usually attached to line scanners for pixel-wise calibration. We define a radiant intensity function for a linear light source and fit it to captured images to calibrate the response function. We applied our method to a line sensing camera to remove streaking noise when scanning and experimental results showed a significant reduction of noise in the system.
