Customer Reviews:

Before choosing David-Starter Kit Laserscanner, I searched information on many websites. Based on my search, I noted that this system is preferred by many people particularly for its accuracy. It is also used by a few Schools and Universities.However, to obtain a certain result in using it, we need to ...

hey, meinste es wäre möglich, mal gerade eben die ungefähren maße anzugeben? also in welcher höhe und entfernung sind der laser und die kamera vom objekt entfernt...? die laserbewegung ist rein rotatorisch und nicht translatorisch?

[sehertest]

@joui04081986

Laser ca. 20 cm über, und 20 cm entfernt vom Objekt. Kamera ca. 20 cm mittig vom Objekt entfernt. Drehachse war ca. 2 cm hinter Laseraustritt.

I do all my own music ....

[Chinespa]

Does anyone know the name of the song in this video? I wanna get that album or single. I also want to hear other music like this and music they made. I am trying to do a lyrics search but with no luck yet. I can't get that out of my head.

[halfmumi]

what is the biggest size it can scan?

[TheXxmad4everxx]

amazing !

[bluemini9]

How did you scan the top of the head? When I trie that, the head was very close to the scan which made it bigger than the rest of the scans.

Also, how did you add the original color to your scan?

[cysign07]

das sieht ja richtig professionell aus :)

sag mal, wie hast du die laser-steuerung gemacht? ist das sehr schwer?

handwerkliche fähigkeiten hab ich...ich würd das dann aus holz mit kugel-lagern machen... aber die steuerung. Schrittmotoren mit ne Steuerkarte, die man mit Davis-Laserscanner synchronisiert?

[sehertest]

@cysign07

Die Steuerung ist mit dem Lego Mindstorms Baukasten gemacht, relativ einfach. Nur relativ teuer. Man kann David auch alles steuern lassen mit so einem ARDUINO microcontroller, das ist mir aber zu kompliziert, dafür reichen meine elektronik Kenntnisse nicht aus. Schau mal im David wiki auf der DAVID Laserscanner Homepage.

[HimmiJoe]

It's incredible how companies can still market their products in the price range of 3,000-30,000 dollars for the same thing as one that is nearly gratis. Sure it can vary in resolution and accuracy, and it may be a bit harder to use. But still, it achieves the same effect in the end - it digitizes tangible things. I just don't get it. If amateurs can do this - why don't commercial companies target us?

[minieggg1]

@HimmiJoe comercal companies use the phase shift of the reflected beam to calculate distance, this uses a camera and uses the brightness to find distance. Commercial laser scanners work in any lighting on most materials over relatively huge distances with almost unlimited accuracy, hence the price large price tag :P

[igehring]

hey, can you help me out please ? How can I partialy merge objects before the final merge, just like its seen on the video ? Thanks

[sehertest]

@igehring

Look at david-laserscanner Homepage / wiki / User Manual for more details

[osallivan231]

have you tried to place the laser verticaly (so it lights along the vertical) and rotate the model smoothly and slowly 360 degrees? I think it would be much faster and easier. The only question is if the program will be able to render on the vertical (left to right)

[FRI00001]

@94lorenz im Baumarkt kannst du erfolg haben oder Conrad ?

[sehertest]

@all

Schaut mal bei David Laserscanner im Shop vorbei:

Roter Linienlaser, fokussierbar, 5mW, mit Steckernetzteil

Typ:LC650-5-5-F(14x45)-NT

[cearcris]

ME GUSTARIA PODER CONTACTARTE PARA VER SI ME PUEDES ASESORAR EN HACER ESTA MÀQUINA, O BIEN, ME PUEDAS PASAR PRESUPUESTO PARA COMPRÀRTELA......

I would like to contact you to see if I can advise on MAKE THIS MACHINE, OR YOU CAN CHECK ME budget to buy.......

[94Lorenz]

Da ich jetzt herausgefunden habe, das du Deutsch sprichst.

Hier noch mal meine Frage.

Was für einen Laser benutzt du ( Ich weiß nicht wie ich eine Laserlinie

erzeugen kann) und wo kann man den kaufen?

[94Lorenz]

What kind of Laser did you used and where can I get it???

[pkcheeze]

@94Lorenz line lasers are usually quite expensive, so you can either get a normal laser and shine it through the stem of a wine glass or get a torch and on the end put two pieces of opaque tape leaving a very thin gap

[Djich1]

echt geiles programm Top

[ariasd]

Hi,

I was wondering if the texture is scanned as well or not ?

Thank you.

[sehertest]

@ariasd

Yes, the texture photo taken with the webcam and David laser scanner. No post-processing.

[pkcheeze]

@sehertest is that bump top in the background? :P

[sehertest]

@pkcheeze

No, it`s Real Desktop :P

;-)

[AIDG]

The rapidshare link is broken. Is there another place to download the mindstorm nxt program?

[sehertest]

@AIDG

i can send a mail...

[scobob]

rather than the music which adds nothing, you should explain what you are doing.

[sehertest]

@scobob

for more information go to the website "david laserscanner"

[SiliconeSlave]

Very nice! I want to start building my own as well.

[narutokunkun1234]

can I use a Digicam as a webcam, my digicam supports this feature.

[sehertest]

@narutokunkun1234

i dont know this kamera

[ocnenjitram]

can you help me out?

in your discribtion you have a link to download the software.. is that the free one? or the illegal downloadable one? and if it's the last.. the link does't work by me, can you put a new link in it?

[sehertest]

Look at:

david-laserscanner dotcom

[ocnenjitram]

but that is the freeware, i want to download it with torrent/nzb, so i can hafe the real version! or soen't work that properly? and if i hafe the free ware can i save is to .obj?

[sehertest]

Yes, you can test the free version. The differences between the two versions are available on the website. I work in the video with the full version which I bought.

[gverhoev]

Superb! Wonderful job. Could you please put the file online on Rapidshare, as I'm extremely interested in this one. A few more questions: do you have the best results with the Red laser or did you also try a green one? Which settings do you use for you webcam (as I have the same, but the results never look so good as yours).

Many thanks in advance!

[sehertest]

What kind of files? The Figure is on Turbosquid. See link on the right.

I have only a red Laser. Settings are different for each object. Try the Laserline darker during scanning. Too bright, makes a rough surface quality.

[migero2]

what camera is that ?

[sehertest]

Logitech QuickCam Pro 9000

[Giganotosaurus1993]

I have a few questions, mainly because I tried this yesterday and had an utter failure, lol.

1. Does the room have to be in complete darkness?

2. I'm scanning in a dark blue colored object, does that matter?

3. Do the calibration points need to be bigger than the object?

4. Last question, does the laser need to be completely on the calibration plane? Or can it be going off the sides?

Nice scanning :)

[sehertest]

1. No

2. Yes, bright is better. Take the case of dark objects powder.

3. Yes, you scan only the aera of calibration points

4. Out of calibration plane is no problem

[Giganotosaurus1993]

Thanks man :)

[ocnenjitram]

gott the same almost..

[TAKIZAWAYAMASHITA]

one problem the david software always says failed to calibrate camera even when i try manual calibration

[sehertest]

Look at:

david-laserscanner dotcom / Manual / Camera Calibration

[DefCur]

holy shit...

[djsbriscoe]

Hi,

What is the name of the music in the background and the artist?

Thanks.

[sehertest]

Hi,

the music is made by myself. All my music is self-made.

So at least there are no problems with the Copyright

[assmannsven]

This is brilliant! Where can I get the details to your setup. I have Lego Mindstorm but your programm would be nice!

[sehertest]

Look the Link on the Top right

[baccus61]

This program has come a long way since it was first released and now it does beautiful scans. I think I will make one soon to complement my wood router.

Thanks for putting together the video.

[Khalid1349]

Thanks for sharing the video:)

[e001100]

Can only the plasticine and metal shading be choosen? Reflected brilliace data of the laser should be used to store information of material roughness.

In this video, clicking to right then to left is very boring.

[geberticii]

thanks it's perfect scanning
