As long as we were dealing with a flat and distributed object, it was enough to take the data just from the central pixel of the depth map. We recorded the LiDAR data for distances from 20 cm up to 5.5 m. We used a 5 cm measurement step for distances up to 1 m and a 50 cm step for the larger ones.
4 wrz 2010 · My method for estimation is as follows: Stand 10 feet from a wall and look at the image on screen. Note the points on the wall at the left and right side of the image and measure the distance. Then use trigonometry to calculate the angle.
28 paź 2021 · the larger aperture of the iPhone 13 Pro Max's wide lens (in photography, a lower number means a larger aperture, so ƒ/1.5 is a larger aperture than ƒ/1.8) means it will also have reduced depth of field as compared to the iPhone XS' wide lens.
With the sensor size, image pixel resolution, focal length, and known subject size, you can back-calculate (well, estimate) the distance between the camera and subject (assuming that the subject is reasonably parallel to the camera sensor plane).
5 cze 2018 · Thanks to Apple's ARKit 2.0 augmented reality framework in iOS 12, we now have a "Measure" app built right into our iPhones that can measure real-world objects. No more physical tape measure or ruler. No more guessing. Just whip out your iPhone, open the app, put your camera, and get measurements.

The iPhone 12 display has rounded corners that follow a beautiful curved design, and these corners are within a standard rectangle. When measured as a standard rectangular shape, the screen is 6.06 inches diagonally (actual viewable area is less).
