Research on 3D Scanning Solutions
We want to build a business around the 3D Custom-Fit technology. So, finding a reliable, affordable, and easy-access 3D scanning solution is critical. The easier it is for the customers to get 3D scanned, the more likely they will choose our products and services.
There are many 3D scanning solutions. And obviously, we should focus the small, portable solutions. Because only small devices can be carried around and become popular. The ideal solution is that smartphones have a built-in sensor that can do the 3D scanning.
When we first started our company in 2016, we were using an external device, called the Structure Sensor, as the 3D scanning tools. Here’s the link to this product: https://structure.io/structure-sensor
Originally, the Structure Sensor is used on the iPad. In the package, there’s a bracket that lets you attach the Structure Sensor to the back of the iPad. And the camera on the back of the iPad has to align with the Structure Sensor to get accurate results. The Structure Sensor team provides developer SDK and a sample App to start with.
Later in 2017, we developed our own App and also a phone case to hold the Structure Sensor. At that time, we thought the iPad was too big and not as popular as the iPhone. It works great most of the time, but with some flaws. For example:
- The Structure Sensor often loses alignment and needs calibration. The process is hard to learn for new users.
- The Structure Sensor has its own battery. We need to charge it regularly. Otherwise, we will face the awkward moments when we need to scan somebody but have to charge it first.
- The Structure Sensor has a unique cable connecting itself to the iPhone’s lightning port. The cable could break or disappear if not taken care of. And it is also very expensive to buy a new one.
- The Structure Sensor is not designed for scanning the face. Its primary usage is for AR, room scanning, and object scanning. So the density and accuracy of the laser projected are far from ideal for scanning faces.
