I routinely do site visits at concert performance venues, churches, performing arts spaces, etc. where I am tasked with taking measurements and drawing a Sketchup model to then import into an acoustic modeling program for loudspeaker placement and prediction. The rooms do not need to be overly detailed and I am only modeling the inside of a space such as a church.
Many times I do not have floorplans to draw from so right now I am taking measurements using a laser measure, making notes and taking pictures.
I am interested in other ways of going about this to improve my workflow. I’ve been seeing videos of people using point cloud scans but mostly for outdoor use and not for a medium/large interior space. I know there are solutoins like Canvas.io but that seems to be only for small room applications. I’ve also been looking at Matterport but I would have to pay $49 per site to export the point cloud data, plus a very expensive Leica or other camera that can take these masurements, and a $699/annually for a Sketchup Studio subscription.
I don’t necessarily need point cloud data but I’m looking for a way to potentially use photogrammetry in an interior space to take basic measurements, then model a room based on those measurements. It does not have to be 100% accurate, but something scanning related seems like it would speed up the process tremendously… Has anyone done anything like this for a medium/large interior space?
For example, I recently visited a church that was about 150’ deep x 55’ wide x 46’ high. There were columns in several areas that needed to be modeled. If there were a way to take multiple 360 degree camera measurements and slice them together, I would be able to have all the data I would need I would think instead of manually measuring everything.
