Precise Measures While Doing Interiors

If you failed math in school or hated triangles, this theory may go bouncers on you. I’m not giving you the Pythagorean theorem to prove but simply telling you of this handy device that could get you the perfectly angled walls and smooth looking interiors. The Red Point Measure is a digital measure that applies current laser ray measure techniques to mathematics formula of triangles by simply measuring a target from afar.

Comprising of two detective arms and a red light this is how the instrument is used:
“Just swing the two detective arms and use red light to point at the 2 ending points of target length, and then the length will be shown on the screen.”

Do away with the climbing up and down to the target, or asking someone to help you to measure big or long objects. Simply DIY!

    Looks like a great idea. It might be an easy thing to add a camera to take a picture of each measurement.

  • Drew says:

    Great idea and design! The only thing I would suggest adding is some type of electronic leveling sensor built in so you’d know what angle you were tilting the device at

  • Eric says:

    I agree with Drew, the leveling would be an issue. While trying to “precisely” line up one dot on an edge/corner, you have to then “precisely” line up another. I think without a level this would be quite difficult to get precise results from…

    • Eric says:

      Another thing is that I’m no tripod. So these dots being projected several feet away are going to shake like crazy, because of that so are the measurement results. Is it going to take the median from several measurements? Not very accurate… With all the things required to make this more accurate it almost is just as bothersome as a tape measure. I mean this would be great for an average guesstimate, I just really doubt it’s “high accuracy.”

    • Ritesh Kumar Sethia says:

      If You add the leveller used while making furniture which is an easy thing to add , it can be greater.Your idea is great though.

  • brack says:

    I love this. It appears to be manufactured with interior designers in mind, but I wonder what the “contractor” version might look like?

  • Ekove says:

    They’d need high level lasers to make it easier to see, and even then there’s the issue of hand shake. As pretty as it is, the measurement tape seems more reliable, at least for places you can actually reach. So, if you get this, you’ll probably still need to carry both, unless it gets a built in measurement tape.

  • M says:

    Anyone who used a laser meter without leaning it to some fixed object, knows the result is more of an informative value.
    To handhold the device and position two laser dots to corners of a room precisely enough to get a usefull measurement, is in my opinion impossible.
    Good design though and if you use some leaning point or a tripod, it could be quite useful for basic measuring of hard to reach things (still not too precise ofcourse).

  • Carl says:

    This measures in increments of .5cm When you are 4m back from a surface you are measuring a slight alteration in aperture from the user will result in a large change on the object being measured. I can see this being hard to use. don’t get me wrong i like the ideology but it requires finesse.

  • vahid says:

    it does have some issues that need sorting out, but the concept is good

  • Eric says:

    Yes props to the designer for doing a great job. I think it looks very nice, and believable from a manufacturing standpoint.
    My only suggestion to improve stability (and not require carrying around a tripod,) would be putting a gyroscope in the center. Pull the cord, then its centrifugal force keeps it at least as stable as a “camera shake” filter on a camera would. So a little movement, but way less jerky and more slow…
    Does anyone know if two smaller gyros spinning at the right angles could cancel out maybe 1 axis of movement? Tilting could become much easier then. Just a thought…

  • John says:

    interface it with a digital camera and you have a useful tool for interior designers to get a quick and dirty measurement set. Also, if the camera has a tripod you solve the handshake problem. It would be easy to imagine software that superimposes lines over the digital photograph showing distances.

  • Amine says:

    great idea !
    and i think that u can add a caemra as Jan Gil say & it will be Perfect !

  • ömer says:

    the design and the idea is good but somethings absent, how we can know that we get the real dimension, i mean it is hard to make a straight position with 90 degree to the wall

  • ömer says:

    • prodmod says:

      thank you, i was about to mention the same thing. I think the equation only works with at least one known 90 angle, right? It is there between A and C but not labeled. And the photo is deceiving.

      if this was able to workout mathematically, you could avoid the shaky issue by using a built in camera to take a snapshot of the laser at a single point in time. then use image processing to calculate the length between the two dots. You know the angle in the device “Z”, then you can use an ultrasonic sensor to measure the distance from the wall. Then require the person to face the wall head on so you are at a known 45degree angle.. Haven’t worked out the math on it but its off the top of my head right now.

      Actually, even simpler, i wonder if you can also project a single laser line like the leveling devices do. That line is projected onto a wall with two corners, like the photo. and the image sensor will know where the end of the wall is because the line breaks and bends around the adjacent wall. Again still need distance measured from the wall.

      cool idea

  • Marcello says:

    Interesting.. yet, it needs a very accurate horizontal control, somehow as Eric suggests!
    The measurement must be done on an horizontal plane I think 😉

  • prodmod says:

    and in case any one is wondering. using lasers in your product does not make it more accurate and neither does digital.
    it sounds great from a marketing perspective, but if you try to get something made in real life it will take a lot more design effort independent of the “laser” and “digital” parts to get it to work properly

  • Jason says:

    not so much practical…They actually have this device, and saw them measuring length of stuff in distance on the video..However,,,they always had the error between 0.5meter-3 meters which is huge..

  • long says:

    how much?

  • long says:

    i want to see DAtasheet

  • nour says:

    plizzzzzzzz i want this product

    how i cant get it

  • nour says:

    plizzzzzzzz i want this product

    how i cant get it

  • Keith Sherwin says:

    the two lasers are really not required and make simultaneous target acquisition very difficult.
    I have a software solution if you’d like to advance your design.
