Bug Reports / Align Photo in 1.2

« on: January 22, 2016, 04:10:32 AM »

Photo align in more than 1.2 version of the effect is not good, can solve this problem?
When I align photo use PS 1.1.6,the result of align is not bad,But I use PS version 1.2,the result is bad.and I use those same photos.

« on: June 18, 2015, 05:16:57 AM »

I want to classify ground point use python script

Code: [Select]

PhotoScan.DenseCloud.classifyGroundPoints(max_angle=10.0,max_distance=1.0,cell_size=50.0)
It prompt me 'TypeError:descriptor 'classifyGroundPoints' of  'PhotoScan.DenseCloud' object need an argument',
I want to know what's wrong with my script?
pls help!thanks a lot!

General / About tiles convert in photoscan 1.2

« on: March 31, 2015, 11:53:11 AM »

When I output tiles, I found the coorinate system is not available.
I convert TLS files in the Agisoft Viewer to obj obj format. And In the *.obj file, the coordinate of model looks like a relative coordinate, I want to know how to convert it to the geographic coordinates, such as UTM WGS84?

General / How can I export modified model use export tiles

« on: January 15, 2015, 06:20:16 AM »

I modify the model and rebuild texture,And then I want to output the model tiles, photoscan does not consider my post edit models, but also to auto rebuild the model and output.How can I export model tiles use I modified model?

Bug Reports / Question about Optimize Cameras

« on: December 18, 2014, 04:10:19 AM »

When I use ground control points to optimize the alignment, the ground point to display  the error value is 0.01m.
But when I generate DSM(Build dense cloud quality is low), I found that the elevation error with control points have some difference, The error of nearly two meters.I want to know how to solve this problem.Thanks very much!

Bug Reports / question about export matches

« on: November 21, 2014, 09:59:15 AM »

When I export the matches , the output format is ORIMA, I found the output point there are a lot of mistakes. For example: ID=0 will be output in different images, but into the INPHO will find a lot of wrong match, don't know other people have not encountered this problem?

Python and Java API / About Set Map Region python

« on: November 20, 2014, 10:30:25 AM »

I used 1000 UAV images generation model, and the image without distortion correction.Align photo has finished.
I use Python script 1.1 for set map region.But the position is always wrong.

Code: [Select]

# Define: Region [Name,CenterX, CenterY, SizeX, SizeY]
                    MapRegionVec = [C_4,744300,3074400, 300, 300]
                    newregion = PhotoScan.Region()
                    chunk.resetRegion()
    #rotate
                    T = chunk.transform.matrix
                    v = PhotoScan.Vector( [0,0,0,1] )
                    v_t = T * v
                    v_t.size = 3
                    if chunk.crs:
                        m = chunk.crs.localframe(v_t)
                    else:
                        m=PhotoScan.Matrix().diag([1,1,1,1])
                    m = m * T
                    s = math.sqrt(m[0,0]**2 + m[0,1]**2 + m[0,2]**2) #scale factor
                    R = PhotoScan.Matrix( [[m[0,0],m[0,1],m[0,2]], [m[1,0],m[1,1],m[1,2]], [m[2,0],m[2,1],m[2,2]]])
                    R = R * (1. / s)
                    newregion.rot = R.t()
    #set grid center:
    #define float
                    C1=float(MapRegionVec[1])
                    C2=float(MapRegionVec[2])
                    C3=float(MapRegionVec[3])
                    C4=float(MapRegionVec[4])
                    centerUTM = PhotoScan.Vector([C1,C2,0])
                    centerGEO=chunk.crs.unproject(centerUTM)
                    print ("centerGEO:",centerGEO)
                    centerGEO.size = 4
                    centerGEO.w = 1
                    centerLocal = chunk.transform.matrix.inv() * centerGEO
                    centerLocal.size = 3
                    print ("centerUTM=",centerUTM,"centerLocal=",centerLocal)
    #define newcenter
                    newregion.center = PhotoScan.Vector([centerLocal[0], centerLocal[1], chunk.region.center[2]])
                    print ("newregion.center:",newregion.center)
 #define newsize
.......
                     newregion.size = PhotoScan.Vector([xsize,ysize,chunk.region.size[2]])
                     chunk.region = newregion
I don't know what is my code error or 1.1 script error,But I'd use this script is run on the UC camera images have no problem.

Python and Java API / How to run my python script under Network in python API 1.1?

« on: October 23, 2014, 11:00:19 AM »

I wrote a python script to set map region and generate the densepoint and model, but by the time I run on a network(distributed), photoscan can only be run on this computer, and cannot use the network processing,and my network is already configured to process tasks. I wanted to know how can I modify Python script to do this?

General / How to improve the accuracy of models

« on: July 02, 2014, 06:15:25 AM »

I use oblique aerial photography to generate three dimensional model of building, specify the parameters of the camera and imported the POS data, without ground control points. Generate a model of the building as follows:

But it always felt good models that aren't GoogleEarth effect, the edges of the building not obvious enough.
I think Google has used a similar method to generate a three dimensional model of the following figure is  GoogleEarth models.
So I want to know how can improve the precision of the dense point in the PhotoScan and generated mesh better?
