Convert pixel distance to real world measurements. Conceptualize how estimating distance can be applied to other use cases.
4 kwi 2016 · Discover how to measure the distance *between objects* (in inches, meters, etc.) in an image using OpenCV, Python, and computer vision + image processing.
12 wrz 2018 · To be able to select 2+ objects and then enter in a set number of pixels in the right details panel to define the space between them (with options for horizontal or vertical spacing). It's evenly distribute but with precision (instead of having to drag blindly).
22 cze 2023 · pixel size = 2 * tan ( horiz.fov /2 ) * distance / image width in pixels. So at 50 mm on 12 Mpx full frame at 5 m distance you get. tan (39.6°/2) * 5000mm / 4000 = 0.45 mm
