  • On screen measurement software recommendation

    Can someone recommend a user-friendly computer based caliper program? By this I mean, a system you can measure objects "on screen" , say from a JPG file?

      Thanks for the link, but what I am referring to, is a sort of caliper, that "floats" on the desktop, and can be calibrated to a known value, and moved around measuring objects on the screen.

        I use the Mac version and it works great. It is especially helpful if you include in your image a reference scale. Be sure to click the software tab to see all the other on-screen tools they have.

            I've seen but not used that before. My guess is that it is pixel-based andhas an accuracy of +/- 1 pixel. And if thats the case will not accuracy reduce with reducing screen resolution - and vice versa?

            Can I scale it? ie span an oject on the screen and insert a scaling factor when I have physically measured a part? In both "X" and "Y"?

            As I recall, Even had a pretty good suite of this and some other accessories or applications not all that long ago.

            I'd like to see them again too.

              Related question, but is there any measuring software (preferably for Linux) that you give a picture of an object, define XYZ axes with drawing lines and define one dimension and then you can measure from any point to point in the picture and it gives the correct answer?

              Picture an isometric view of a cube that has a non-center hole in top and you know the cube size but don't know the hole position?
              Amount of experience is in direct proportion to the value of broken equipment.

                You have to be careful as these types of applications are favorites for including spyware and other garbage. This one is safe.

                  Sketchup does that as a native function called "Photo Match".

                  By the way, Sketchup just gained a lot more respectability. Google just sold the entire program and team to Trimble for something like 50 to 100 million dollars.

                      It's possible to embed video in Axis.

                      http://wiki.linuxcnc.org/cgi-bin/wik...is_Embed_Video

                      The code base is from http://code.google.com/p/camunits/

                      I dug out an old golf ball styles Logitech last week and getting it integrated into Axis is on my to do list for the summer.

                        I can't tell you Tiffie, because I've recently upgraded my Mac OS and they don't yet have a version for this newer OS. There is a free demo for Windows, though.

                        The vendor claims no spyware, etc., and my experience bears that out. It's worth a try.

                            I use Meazure. I like that it has a zoomed image for increased precision. Free.

                              Just curious if you noticed someone had posted this same question a half hour before you.
