手机室内视觉定位要素识别样本库MIPNS-LIB2.0，包括11类普适性地图定位锚点附属设施的图片样本数据。本数据集利用手机后置相机采集建筑物室内场景中普适性要素的图片，并对同一要素目标按照用户的姿态进行了不同角度和距离的图片采集，使用labeling工具完成样本标注工作。

样本集所包含的普适性地图定位锚点要素类别具体包括：消防栓、火警报警器、门、摄像头、WLANs、安全出口、电箱、门牌、电梯、展板、灯共11类，可适用于教学楼、图书馆、商场等不同建筑物室内场景的要素识别任务。

MIPNS-LIB2.0样本库具体的要素样本数总计为11062个，比例统计如下表1所示。

The MIPNS-LIB 2.0 sample library is a sample library of mobile phone indoor visual location elements recognition, which belongs to a sample dataset of images including 11 types of pervasive ancillary facilities to map location anchors. This dataset was created by manually capturing images with pervasive elements in indoor scenes of buildings using the rear camera of the mobile phone, at different angles and distances according to the user's posture requirements at the time of recognition, and using the labeling sample annotation tool.

The sample subset contains 11 categories of universal elements, specifically including fire cabinets, fire alarms, doors, cameras, WLANs, exits, electrical boxes, door signs, elevators, display boards, lights. It can be applied to the recognition task of different indoor scenes of buildings such as school buildings, libraries, shopping malls, etc.

The total number of element specific samples in the MIPNS-LIB2.0 sample library is 11,062, with the percentage statistics shown in Table 1 below.
