What is the best way to accurately measure the distance between two points on a 360 image using A-Frame technology?

Is there a way to accurately measure the distance between two points in a 360 picture of an interior using the a-frame.io framework?

We attempted converting the unit system of a-frame to centimeters and used two points with known dimensions as a reference. However, we found that measurements taken at other points were not accurate. Any suggestions or formulas that could improve our accuracy?

Thank you.

Answer №1

It seems like there may be a missing piece to make this solution work effectively. Without having the depth-image information, extracting accurate measurements from a single 360° image can be challenging. By incorporating the distance from the camera as a third value, known as depth or spherical coordinates, we can then convert these into cartesian coordinates (x, y, z) for better accuracy.

Without the knowledge of the distance, only a ray can be reconstructed rather than pinpointing a specific point. An additional piece of information is required to determine the exact location along that ray for precise measurements within the image.
