Measure dimensions with iPhone. Use the Measure app and your iPhone camera to measure nearby objects. iPhone automatically detects the dimensions of rectangular objects, or you can manually set the start and end points of a measurement.
In addition, call the distance between the camera and the two points $L$. The camera's field of view ($FOV$) (or angle of view as is more common in photography) can be calculated by $$ FOV = 2\arctan\left(\frac{d}{2F}\right) $$ which, for a scene at distance $L$ corresponds to a scene dimension $W$ equal to
16 lip 2016 · To work out the size of the object on the sensor, work out it's height in pixels, divide by the image height in pixels and multiply by the physical height of the sensor. So the whole sum is: $$ \textrm{Distance to object}(mm) = \frac{f(mm)\,\times\, \textrm{real height}(mm)\,\times\, \textrm{image height}(pixels)} {\textrm{object height}(pixels ...
27 gru 2022 · Your iPhone can use its camera and LiDAR sensor to measure dimensions such as height, distance, and length of nearby objects. And it can potentially replace a measuring tape for household purposes. In this article, let’s see how you can measure height and distance using your iPhone or iPad camera.
