You can, they are just expensive (other than iphone). Maybe 8k for a handheld basic one (e.g. Trion P1), $15k for a drone attachment (e.g. DJI Zenmuse L1) - more for the ones surveyors use proper including the tripod-mount ones. At the consumer end photogrammetry tends to just be so much cheaper that its preferred unless you really need defined accuracy at a high level of detail. Lidar tends to work currently much better in an industrial/professional context because its more accurate. Whether Lidar will make the jump to lower cost / consumer level is the big open question (and basically the same issue as for cars here)
