LiDAR is a remote sensing technology that has been gradually applied in the development of measurement in recent years. Its principle is to sense the distance between the object and the object through light. In terms of smartphones currently sold in the market, the iPhone is the main model driving 3D sensing in the market. In this study, the Light Detection and Ranging function of the iPhone 12 Pro smartphone is applied. The maximum detection distance is 5 meters. The information reflected by the laser light is combined with the main lens camera image information, motion sensing and The new version of iOS and iPadOS is deeply integrated, and then processed with the mobile phone chip to analyze environmental characteristics and obtain scene information. The research results show that the scanned point cloud data is of considerable value for the construction of the 3D model of the current situation parcel. Not only can it meticulously record the shape features of the surface of objects, such as walls, fences, pillars, etc., but also assist resurvey of cadastral map, record and interpret the site boundary during measurement and cadastration investigation. |
