3D Mesh and Point Cloud Generation

I’m amazed with the achievements from eCapture Research and Development SL. Today I’ve generated point clouds and 3D mesh from series of 49 photos taken via mobile vehicle. I’ve tested two products.

The first product, I call it as product A, it requires users with prior knowledge about sensor size, camera focal length, coordinate projection, etc. Experience in handling spatial data is an advantage. Took almost 30 minutes processing time and expensive computational cost (desktop based).

On the other hand, by using eyescloud3d I’ve managed to generate the model within 15 minutes (output as shown). And most importantly, no prior background knowledge needed.

Congratulations to Guillermo, Miguel and the team for your R&D. Fascinating.

Our lab at Universiti Teknologi Malaysia (UTM) have 5 years MoU research collaboration with eCapture Research and Development SL. We have the privilege to conduct scientific research using their products. Students are eligible to utilize it, feel free to let me know if you’re interested.

Royal Institution of Surveyors Malaysia (RISM) Awards

Congratulations to Tang Siew Khing in winning 3 national level awards by the Royal Institution of Surveyors Malaysia (RISM). She presented her Final Year Project (FYP) in a form of research paper last month. The awards are:

  1. Gold Award in Best Paper Category
  2. Innovative Paper Award
  3. Potential Research Paper Award

Thank you to Royal Institution of Surveyors Malaysia (RISM) Geomatic and Land Surveying (GLS) Division, anonymous Jurors, and Universiti Teknologi Malaysia (UTM). This awards means a world to my Sarawakian student in doing her FYP dissertation.

To RISM, keep it up with this good event. This will values our profession growth in the country 👍🏻

and again, Congratulations Tang!!!

 

JSON to CSV Converter

While doing my spatial data mining, I stumbled upon this situation where I need to translate my JavaScript Object Notation files (JSON) to another format, which in my case is Comma Separated Values format (CSV). Trying to find online converters, but somehow most of the converters are limited like file size should be less than 1MB or 100MB maximum, which definitely can’t handle the spatial data I’m working with (almost 1GB/file). And I have multiple of them. Sure, need to add 💵💰 for this for larger files. Then I’ve decided to write this 10 lines Python code to read, filter, format and convert and store it to CSV file. This video (series of images instead) shows how it goes and voila!
