Shortest distance between two line segments - Stack Overflow
I need a function to find the shortest distance between two line segments. A line segment is defined by two endpoints. So for example one of my line segments (AB) would be defined by the two points...
c# - The algorithm to find the point of intersection of two 3D line ...
The line segments between P1 P2 and P3 P4 have their corresponding mu between 0 and 1. There are two approaches to finding the shortest line segment between lines "a" and "b". Approach one: The first is to write down the length of the line segment joining the two lines and then find the minimum. That is, minimise the following || Pb - Pa ||^2

How to efficiently check if two line segments intersect?
Checking whether two line segments have a shared coordinate is a trivial check that you do first, before running the standard line/line intersection math. As for "Line segments shouldn't be considered intersecting just because they share the same slope": slope is undefined for vertical lines, so don't work with, or think it terms of, slopes.
python - How to detect lines in OpenCV? - Stack Overflow
the crossings? Maybe you could group the line segments by angle and distance (and maybe houghLines in addition - but then work on grouped line segments again) and if you know the general appearing of the parking space markings you could perform perspective correction which would make it easiert to compare and group the line segments.
Efficient maths algorithm to calculate intersections
Most of the answers already here seem to follow the general idea that: find the intersection of two straight lines passing the given points. determine if the intersection belong to both line segments. But when intersection does not occur often, a better way probably is to reverse these steps: express the straight lines in the form of y = ax + b (line passing A,B) and y = cx + d (line passing C ...
How do you detect where two line segments intersect? [closed]
Question A: Where do two line segments intersect? You know that two line segments a and b intersect. If you don't know that, check it with the tools I gave you in "Question C". Now you can go through some cases and get the solution with 7th grade math (see code and interactive example). Question B: How do you detect whether or not two lines ...
Plotting numerous disconnected line segments with different colors
In general, any two line segments are disconnected (meaning that their end-points do not necessarily coincide). How to plot this data using matplotlib with a single plot call (or as few as possible) as there could be potentially thousands of records. Attempts Preparing the data in one big list and calling plot against it is way too slow.
How can I check if two segments intersect? - Stack Overflow
This is an "almost" complete solution. the check for s1 == 0 and s2 == 0 only checks if the line segments are parallel and overlap. What if the line segments are "T" shape, i.e, only one point of a line segment intersect with the other?
Finding The Shortest Distance Between Two 3D Line Segments
You say you have two line segments, not two (unbounded) lines. Can you clarify if you need the distance between the line segments, or the distance between the lines generated by the line segments? Example: If one segment goes from (0,0,0) to (1,0,0) and another goes from (0,100,1) to (0,101,1) (both segments are horizontal), what should the distance be? It would be 1 if you took distance ...
