We investigated the benefits of photogrammetry versus LiDAR for generating 3D point clouds.

In recent years, mobile phones utilizing LiDAR technology have attracted increasing attention as an easy way to generate 3D point clouds. Mobile apps such as PIX4Dcatch have gone one step further and integrated this technology with photogrammetry. The ability to combine both images and LiDAR for calibration means PIX4Dcatch can achieve more accurate results, with the ability to reproduce smooth or textureless surfaces – and even white walls.

The purpose of this demonstration, however, was to investigate the effects of scanning-with-LiDAR versus scanning-with-photogrammetry, so we used photogrammetry-only with PIX4Dcatch and then LiDAR-only with a comparison phone app. The point cloud results were processed separately in PIX4Dmatic and revealed the difference LiDAR and photogrammetry can make to your output.
