16 lip 2016 · As noted @matt-grum, the most simple formula to estimate distance to the object is pinhole projection formula: $$ \frac{x}{f} = \frac{X}{d} $$ where \$x\$ is the size of the object on the sensor, \$f\$ is focal length of the lens, \$X\$ is the size of the object, and \$d\$ is distance from nodal point to the object.

2 mar 2018 · But if you know your cameras sensor size (size in both mm and pixels), and if you know its lens focal length (these are relatively difficult questions to find out for most small cameras), then there is a calculator at https://www.scantips.com/lights/subjectdistance.html that will compute the distance. It will be as accurate as your answers ...
15 lip 2016 · Knowing the apparent size of the sphere from the photo and all internal camera parameters is it possible to estimate the distance from the camera to the sphere? There is an equation, more used in lens imaging that is useful: object_image_size = (real_object_size * lens_focal_length)/object distance

19 kwi 2024 · Most distance problems can be solved with the equations d = savg × t where d is distance, s avg is average speed, and t is time, or using d = √ ( (x2 - x1)2 + (y2 - y1)2), where (x 1, y 1) and (x 2, y 2) are the x and y coordinates of two points.

8 mar 2023 · This tutorial discusses important conceptual examples of distance. And the answer is given with the example. So, you will have no difficulty in understanding. If displacement of a particle is zero, then distance will be. must be zero. may or may not be zero. cannot be zero. depends upon the particle.
Distance is a scalar quantity representing the interval between two points. It is just the magnitude of the interval. However, Displacement is a vector quantity and can be defined by using distance concept. It can be defined as distance between the initial point and final point of an object.
