Re: ICP best registration with 4 points clouds.

i understand that the .registered one is not a new cloud but is the DATA one moved on the MODEL one. but i don't undersand the utility of this process ! Finaly the function merge is a sort of ICP Its self?

Re: ICP best registration with 4 points clouds.

sorry but i have to contraddict you. When the process ends on the DB tree appears a new cloud, named xxx.registered with the same numbers of point of the DATA cloud...is there something wrong on the screen ?i don't understand this way.Whaen i do the ICP regstration i don't have to lose points as in ...

Re: ICP best registration with 4 points clouds.

hi daniel, there is another problem with the ICP registration. Maybe a bug. When the ICP ends, the new cloud generated (xxx.registered) has only the number of points of the DATA one. how can it possible ?all the points of the MODEL clud disappeared. i thought to get a cloud with a number of points a...

SIGMA and STANDARD DEVIATION

Hi Daniel, sorry i would to ask what is the difference between SIGMA and STANDARD DEVIATION. i compute a distance between a cloud and its best fit plane by the function "compute cloud/mesh distance" and i see the aprox results(max, min, mean and SIGMA wich is a st. dev). Then i compute the...

Re: Cross section slices "bug"

Hi Daniel, the creation of profiles is based on a curve fitting process, i would like to know the equation that CC uses to fit this points. if it is possible.
Thanks a lot

Re: unit of measure (density;gradient)

Hi Daniel, i 'm writing my thesis but i still have few questions for you ;)... - which unit of measure has the gradient ( degrees?)? - why the "gauss: mean" value is equal to 0.0000? when CC compute the distance between a fit plane and its cloud returns me a Gauss distribution but it don't...

Re: unit of measure (density;gradient)

hi daniel, honestly i didn't understand so much your speech, when you say "or more generally that its values can't change faster than the distance between points" what are you going to explain ? i have a cloud wich is derived from a registration from 4 clouds picked up by laserscanning. i ...

Re: unit of measure (density;gradient)

thanks Daniel i understood, another thing i would ask you... the gradient' s unit measure ?I have data raw fron laser scanner and i don't know if choose YES or NO when CC ask me if the scalar field is composed by euclidian measures...and CC gives different out puts if you change one or the other opt...

Re: DXF problems in AUTOCAD

i' m here with my Professor that follow me on this thesis and we both don't understand, because we are able to draw on AUTOCAD but we don' t understand why with this file when you click the comand LINE the cursor disappear and we can't track any lines. We thought that it could be a problem by the ex...
