Easy to follow Tips & Tricks for better Photogrammetry

Introduction

Perfection is the most significant thing when carrying out any task. Any work doesn’t have a meaning if it has not been up to the mark. However, for achieving perfection, some standard steps should be followed.

This blog talks about the tips and tricks to be followed for carrying out a photogrammetric survey in a better way. Photogrammetry scanning will appear overwhelming initially – with such a large number of variables to manage. On the other hand, it takes a lot of trial and error to work out best practices. Photogrammetry has endless potential. But, it needs keen observations and some recommendations to urge prime quality models. Here are some basic tips to follow the right direction.

Steps to follow for a better Photogrammetry

1. Avoid reflective footages: Simply avoid taking footages of reflective objects. If not taken care of, the software photogrammetry software might identify the reflections, and the results would not meet up the requirements.
2. Make use of sufficient ambiance: Capture photographs of objects placed in an adequate lighting condition.
3. Avoid large areas with solid colors: Try not to capture more prominent regions having solid colors. If this isn’t followed, the software might not recognize the unique areas of the object. This will further result in a 3D mesh containing large holes.
4. Turntables are the best: For taking perfect snapshots of small articles, it is always better to use a turntable and adjust your camera in one place. It undoubtedly reduces your efforts in making adjustments in camera positions which is a pretty tedious job.
5. Use manual camera settings: When taking snapshots of the object, prefer opting for manual camera settings. This results in the consistent quality of photographs which gives better results.
6. Capture more angles: While taking snapshots, try to acquire every single corner of the object. This will help the photogrammetry software to deliver you better results.
7. The perfect beginner software: Software does not matter much in photogrammetry. What matters is the quality of images one captures. Almost every software produces the same variety of photogrammetry 3D models, but for a beginner, 123D Catch is the best one to start with photogrammetry.
8. Patience and practice: It takes a lot of time to attain perfection in photogrammetry. Have patience until you achieve the perfect level and it is only possible if you practice it regularly.

And that’s all!

Conclusion:

Photogrammetry is nothing to do with high-quality skills. It’s just that one needs to carry out simple steps that too with perfection as discussed above. The above guidelines would undoubtedly prove to be helpful in creating exceptional quality 3D models.
