Abstract

This paper focuses on three-dimensional measurement system of printed circuit board components. Most automated optical inspections suffer from shadows and reflections obscured by the components. We propose a new method to restore shadow and reflection regions of components for accurate shape measurements, which defines shadow and reflection regions for restoration. The region is restored with a variational auto encoder-based restoration network. It is efficient to input information about both shadow and reflection region to restore the region. Additionally, long skip connection is added to VAE for improved accuracy. We confirmed its superiority through experiments by comparing its performance with other restoration networks such as cycle generative adversarial networks and coherent semantic attention inpainting.

基于 VAE 的用于 PCB 轮廓测量的 3D 图像修复方法

本文的重点是印刷电路板元件的三维测量系统。大多数自动光学检测都会受到被元件遮挡的阴影和反射的影响。我们提出了一种恢复元件阴影和反射区域以实现精确形状测量的新方法。该区域通过基于变异自动编码器的还原网络进行还原。输入阴影和反射区域的信息来还原区域是非常有效的。此外，VAE 还添加了长跳接，以提高准确性。我们通过实验证实了它的优越性，并将其性能与其他修复网络（如循环生成对抗网络和相干语义注意涂色）进行了比较。
