VisionPro ViDi

复杂检测、零件定位、分类和 OCR 方面的突破

在脱气过程中,袋式电池的形状会有些不规则。在夹具化成之后,袋式会被压熨平以使表面光滑。软袋一定要是均匀、无皱、无弯曲的。在这些阶段,电池制造商会使用自动检测系统来捕捉表面缺陷。软袋的复杂表面纹理会产生混淆性的噪点背景,可能会遮挡皱纹、气泡和其他缺陷。软袋的视觉外观可能会有很大差异,使得难以搜索所有缺陷。

VisionPro ViDi uses deep learning-based vision algorithms to identify defects, such as bubbles and wrinkles, by learning from annotated images. The model learns the normal appearance of a pouch’s surface, including natural variations that don’t constitute defects. All features that deviate from the model’s normal appearance are characterized as anomalous. In this way, VisionPro ViDi reliably and consistently detects all anomalies without the need for extensive defect libraries.
