I work in the thoroughbred industry. I am interested in capturing a 3D model of a racehorse (at rest) to later use in a dataset for analysis.

A recent paper (see "Body measurement of riding horses with a versatile tablet-type 3D scanning device") used the iPhnoe 12, a commerical app (Scandy) and LiDAR to create 3D models of the horse. It reads as a fairly straightfoward process, however I was wondering if there was any benefit to using Object Capture over LiDAR. It would seem as easy to walk around the horse and capture a video and then create the process to extract frames from the video for Object Capture?

In terms of creating 3D models, is one method better/more accurate than another?

The Object Capture APIs introduced in RealityKit 2 can use depth data collected from a LiDAR Scanner. The Scandy app probably collects depth data from LiDAR and images from the camera to create 3D models, which is similar to what our Object Capture APIs do.
