随着新能源技术的发展，电池的应用越来越广泛，例如应用于手机、笔记本电脑、电瓶车、电动汽车、电动飞机、电动轮船、电动玩具汽车、电动玩具轮船、电动玩具飞机和电动工具等上。裸电芯作为电池的重要组成部分，裸电芯的质量状态也越来越被人们所重视。
目前，一般采用视觉检测的方式对裸电芯的表面是否合格进行检测，但由于裸电芯的多个表面均需要进行检测，为了适用不同表面的情况，裸电芯的各个表面分别需要配置不同的相机，这就导致了所需的相机的数量多和种类繁杂，且相机位置分散，容易导致对裸电芯表面是否合格的检测结果效率低、准确率低。
示例性的，裸电芯可以作为电极组件，其中，电池单体一般包括电极组件。裸电芯包括正极、负极以及隔离件。在电池单体充放电过程中，活性离子(例如锂离子)在正极和负极之间往返嵌入和脱出。隔离件设置在正极和负极之间，可以起到防止正负极短路的作用，同时可以使活性离子通过。裸电芯的可以为卷绕结构，示例性的，裸电芯中的正极片、负极片卷绕成卷绕结构。裸电芯还可以为叠片结构，示例性的，裸电芯中的正极片、负极片可分别设置多个，多个正极片和多个负极片交替层叠设置。
在相关技术中，为了提高对裸电芯的表面的检测精度，常常采用人工查验的方式对裸电芯的表面进行逐一检测或者抽检。然而，随着裸电芯的表面生产过程对品质的要求越来越高，以及生产速度的提高，通过人工查验的方式不仅给检测人员带来极大的工作压力，还可能存在着检测不到位和工作效率低等问题，随之也造成的了人力成本较高。
