Possible application of low-cost laser scanners and photogrammetric measurements for inspections in shaft sinking process

Abstract

Article aims to present possibility of application low-cost LiDAR scanner of iPhone 13Pro for workings inspections in mining shaft sinking process. Main goal of research was to verify accuracy and usefulness of generated 3D models. Measurements were conducted inside model of mining shaft on the surface. Based on validation, conducted with use of professional TLS, iPhone 13 Pro LiDAR scanner usefulness was proved for inspections that dont need high accuracy. Tested iPhone 13 Pro LiDAR scanner measures up to 5m with accuracy class 2,5. With simultaneous camera recording provides quick triaxial reflection of object with color and texture of material.
