## What is Partometer3D measure on photo?

Partometer3D is camera measure app for area, perimeter, length, ratio, circle parameters, angle measurements. It can be used as a ruler or tape measure for accurate measurements on pictures / photos. This app allows users to make measurements in any defined plane in 3D space. 


Info and demo video: http://goo.gl/UpCKrR

The measurement / object plane doesn't have to be parallel to the camera plane. 
It expands number of situations where application can be used. For example, big objects now can be measured by taking a picture from a side, objects and distances that are difficult to reach can be measured as well. 

Partometer3D has the same application area as "Partometer - camera measure", but gives you more flexibility and power. Angle Mode can be used for roof angle measurements. This data can be used in SolarMeter  app for solar energy calculations.
The app has the  following distinctive features:

- measure in any selected plane in 3D space
- Length, Angle, Area, Circle Modes
- add/delete  any number of measurement/ruler lines
- values assigned to each ruler line
- measure objects in different directions
- share measurements
- find object ratios, if you don't need absolute measurements
- compare object parts to each other
- use custom and predefined reference objects
- angle measurement partially visible or out of view
- irregular shaped area measurements

Partometer3D uses a phone/tablet camera and any available object with known size as a reference to perform measurements. To define the measurement plane a rectangular object  (sheet of paper, credit card, custom object) is used. 

The App shows measurement results in different units: meters, millimeters, centimeters, feet, inches based on user settings. It also calculate dimensions of the object in relative units with respect to  the reference object (ROL). 
    
There is an option to make a picture or upload picture from Library. Zoom View feature helps to align object boundaries accurately.

"Partomter3D - camera measure" can be very useful if you need to measure bigger distances on a plane, where the simple ruler or tape measure  is difficult to apply.

### 3/5 — Sort-of works

*2024-12-08, version 1.0.9*

It’s great that it lets you load a photo, but the buttons went away to control the rest of the app once a photo was loaded. Can’t switch units after loading. Did what I needed through so worth the purchase

### 1/5 — Camera not turning ON

*2021-07-21, version 1.0.9*

Camera not turning ON

### 5/5 — AleklyamBurt

*2021-05-21*

Great

### 1/5 — Brain-dead app

*2021-05-17, version 1.0.9*

Very little functionality with lacking control

### 2/5 — Not very accurate

*2020-02-14, version 1.0.8*

I bought this for the radius measure but it just isn’t accurate enough

### 5/5 — Fantastic

*2019-06-07, version 1.0.8*

This app is awesome! I can import a photo,  define a plane and then measure an angle in that plane. I've not seen anything like this work half as well. Fantastic.

### 5/5 — Works very well with iPad Pro 9.7"

*2019-03-20, version 1.0.8*

A great little App, Thanks.
I expect to be using this a lot !!

Just a couple of 'feature requests'
Please consider providing:
1. The option to use 'landscape' orientation
2. A choice of colours for the rulers, etc. [fine white lines are not particularly legible on some images]

P.S. the 'info' button just takes me to the iPad's home screen.

### 5/5 — Pretty good

*2018-07-20, version 1.0.7*

Useful app, managed to measure machined components (circular) at an flat angle to camera, importing photos from camera roll. You can get sub millimetre accuracy (3 decimal places) & you can zoom right in on details. Easy to use, though I had to check manual to find out ROL is reference length (blue line). 
It’s only a couple MB size, which is great!

### 4/5 — 사진이깨져요

*2017-11-22*

사진 불러오고나 찍으면 화질이 떨어져버리네요 
기종은 아이패드 프로입니다.

### 2/5 — Only measures lined

*2017-05-24, version 1.0.3*

Unfortunately I couldn't figure out how to measure irregular objects or item with curves. This makes the program only as useful as a ruler.
