“…The iPad Pro has a resolution between 500 up to 16000 points, producing point clouds with fewer points than TLS and smaller file weight. (Murtiyoso et al, 2021) evaluated the quality and usability of the iPad Pro from a Solid-State LiDAR (SSL) perspective. The authors compared the results of acquisitions using SSL versus TLS and photogrammetry to obtain point clouds.…”

Abstract. Recent integration of LiDAR into smartphones opens up a whole new world of possibilities for 3D indoor/outdoor mapping. Although these new systems offer an unprecedent opportunity for the democratization in the use of scanning technology, data quality is lower than data captured from high-end LiDAR sensors. This paper is focused on discussing the capability of recent Apple smart devices for applications related with 3D mapping of indoor and outdoor environments. Indoor scenes are evaluated from a reconstruction perspective, and three geometric aspects (local precision, global correctness, and surface coverage) are considered using data captured in two adjacent rooms. Outdoor environments are analysed from a mobility point of view, and elements defining the physical accessibility in building entrances are considered for evaluation.

“…Berdasarkan sketsa awal tersebut, dapat menjadi pertimbangan dalam menentukan metode pemindaian ruang yang akan digunakan. Sensor LiDAR iPhone yang diterapkan pada gawai dalam pemindaian data dapat menghasilkan informasi tangkapan geometris yang baik, dengan faktor pencahayaan menjadi aspek penting pada saat proses pemindaian [9]. Sehingga sebelum pemindaian dilakukan harus dipastikan kondisi objek yang akan dipindai mendapatkan pencahayaan alami dari matahari (daylighting) yang memadai pada objek ruang luar maupun ruang dalam bangunan, dengan demikian pada saat proses pemindaian tidak memerlukan cahaya tambahan.…”

ABSTRAKDokumentasi merupakan bagian integral dari pengumpulan, penyimpanan, dan pengelolaan catatan arsitektur, penelitian, dan dokumen bangunan dalam arsitektur. Lamanya waktu dalam proses pendataan lapangan dan keakuratan data yang diperoleh merupakan kendala yang dihadapi dalam proses pendataan lapangan untuk mendapatkan data dokumentasi arsitektur. Kemajuan teknologi kamera pada smartphone semakin meningkat. Dengan kemajuan teknologi saat ini, fungsi kamera pada smartphone tidak hanya sebagai alat pengambilan gambar fotografi tetapi sudah berkembang ke arah pemindaian objek. Pemindaian benda bangunan telah banyak menggunakan teknologi pemindaian objek untuk mendapatkan tangkapan visual tiga dimensi dari ruang atau massa bangunan, salah satunya dengan metode 3D Scanner. Penelitian ini bertujuan untuk menguji dan membandingkan metode 3D Scanner dengan menggunakan dua metode pengumpulan data yaitu kamera spot dan kamera dinamis. Hasil penelitian ini menunjukkan bahwa sensor LiDAR yang terdapat pada iPhone memungkinkan pengguna menggunakannya dalam kegiatan survei untuk mengumpulkan data outdoor dan indoor yang ada. Berdasarkan analisis uji One Way Anova diperoleh P-value sebesar 0.976. nilai P-value<0.05, yang berarti tidak ada perbedaan antara Dimensi yang dipindai dengan metode statis (X1), metode dinamis (X2), dan penggunaan laser distance (X3). Pelaksanaan pemindaian dengan metode statis memerlukan ketelitian dan kecermatan, mengingat keterbatasan jarak pemindaian dan pergerakan alat putar 360-tracking iPhone. Pada penggunaan metode pemindaian statis, diperlukan beberapa titik pemindaian dan intensitas pemindaian.Kata kunci: sensor lidar, pemindaian statis, pemindaian dinamis, ABSTRACTDocumentation is integral to the collection, storage, and management of architectural records, research, and building documents in architecture. The length of time in the field data collection process and the accuracy of the data obtained are the obstacles encountered in obtaining architectural documentation data. Advances in camera technology on smartphones are increasing. With current technological advances, the function of the camera on a smartphone is not only a tool for taking photographic images but has developed for scanning objects. Scanning of building objects has widely used object scanning technology to obtain a three-dimensional visual capture of the space or mass of a building, one of which is the 3D Scanner method. This study aims to test and compare the 3D Scanner method using two data collection methods, namely spot cameras and dynamic cameras. The results of this study indicate that the LiDAR sensor found on the iPhone allows users to use it in survey activities to collect existing outdoor and indoor data. Based on the One Way Anova test analysis, a P-value of 0.976 was obtained. The P-value <0.05 means there is no difference between the Dimensions scanned with the static method (X1), the dynamic method (X2), and the use of laser distance (X3). Scanning using the static method requires accuracy and precision, considering the limitations of the scanning distance and the movement of the iPhone's 360-tracking rotary device. Several scanning points and intensities are necessary when using the static scanning method.Keywords: lidar sensor, static scanning method, dynamic scanning method,

“…Several studies have shown the Apple LiDAR applied within disciplines ranging from anthropology, terrestrial ecology, and cryosphere science. Within these domains the LIDAR scanner has been used to document cultural artifacts in 3D [30,31], inventory trees in forests [32], and monitor snow depth changes [33].…”

Sandy beach and foredune environments are common throughout the Great Lakes region and world. Coastal landscapes are dynamic and vulnerable due to water level fluctuations, high-energy storm events, and human disturbance. Standard methods for measuring geomorphic transformations over time include small-unoccupied aircraft systems (sUAS), but it is costly and spatiotemporally limited. To document the utility of the Apple LiDAR for coastal mapping, we quantitatively evaluated the accuracy of Apple’s light imaging detection and ranging (LiDAR) scanner in comparison to high precision RTK-GPS paired with sUAS to map geomorphic change at Port Crescent State Park in Lake Huron. Benchmark elevations were measured via RTK-GPS and the sUAS and Apple LiDAR elevation measurements were compared to these benchmark elevations to calculate percent errors. Low percent errors were documented, which allowed for further analysis of spatial differences between the two methods in both mapping morphology at a single instance in time as well as change over several months (in response to wave events). Spatial patterns are consistent between the DEMs, and large geomorphic transformations, such as the formation of a berm, were detected in both DODs. Differences between the two survey elevation models arise due to the Apple LiDAR’s capability to detect the finer-scale sandy contours with the foredune, suggesting the scanner can be used to map in areas with rugged topography and/or vegetation presence. Coastal managers can utilize the Apple LiDAR as an accessible way to map geomorphic change quickly and accurately, which can promote the development of proactive and resilient management plans.
