Python and Java API / How to use removecomponents

« on: December 30, 2015, 03:42:48 PM »

Hi  guys,

I'm trying to integrate removeComponents into my workflow but I can't get in to work.

This is the code I'm using:

Code: [Select]

def removethecrap(chunk):

    doc = PhotoScan.app.document
    chunk = doc.chunk
   
    if chunk.model:
        chunk.removeComponents(40000)
        print("Crap removed.")
        return 1
    else:
        print("No model. Script aborted.")
        return 0
It seems to run when I use this code, but I don't get any result. I would expect this to remove components smaller than 40k polygons, but no matter what I set this threshold to nothing really gets removed. Anyone have any suggestions as to what I'm doing wrong here?

Python and Java API / Set updateregion as a function of a scalebar size

« on: November 10, 2015, 01:56:23 PM »

Hi everyone,

I'm trying to do something fairly simple: set the update region in my project as a function of a scalebar size instead of using standard integers as these give different results for each project.
The syntax I'm using is this:

Code: [Select]

updateregion.size = [ab.distance*10,ab.distance*5,ab.distance*5]
The scalebar size is set previously as such:

Code: [Select]

for camera in chunk.cameras:
        if camera.label == '101.jpg':
            c1 = camera
        if camera.label == '102.jpg':
            c2 = camera
   
    ab = chunk.addScalebar(c1, c2)
    ab.reference.distance = 0.366
This doesn't seem to work, the script breaks down at this step yet it works if I use standard sizes like this for the updateregion:

Code: [Select]

updateregion.size = [12,4,4]
Am I just using the wrong syntax in "ab.distance*10" ? I've been over the documentation for this and I can't figure this out.

Thanks!

Python and Java API / Load cameras from folder and mask with background from folder

« on: April 09, 2015, 04:55:33 PM »

Hi guys,

I'm trying to do what it says in the title

I can load the images no problem, but then I would like to apply for each image a mask made from the background image with the same name. I con't figure out why photoscan doesn't like my function that defines the path to each background image, does anyone have any clues?

Code: [Select]

import sys
import operator
import os
import PhotoScan
import math

label = "Script scan"
projectionImagePath = PhotoScan.app.getExistingDirectory("Please choose the folder with projection image files:") + "//"
backgroundImagePath = PhotoScan.app.getExistingDirectory("Please choose the folder with background image files:") + "//"


doc = PhotoScan.app.document
chunk = PhotoScan.Chunk()
chunk.label = label
doc.addChunk(chunk)

files = os.listdir(projectionImagePath)
file_list=[]
for file in files:
if file.endswith("jpg"):
filePath = projectionImagePath + file
file_list.append(filePath)

chunk.addPhotos(file_list)

backgrounds = os.listdir(backgroundImagePath)
background_list=[]
for file in backgrounds:
if file == camera.label:
backgroundFilePath = backgroundImagePath + file
chunk.importMasks (path='backgroundFilePath', method='background', tolerance=12)


The error that I get when running the script is :
"Can't load image:
backgroundFilePath"

Thanks!
