Description

Distance between objects, length distortion correction and drawing system through image analysis}

The present invention relates to a system for correcting distance and length distortion between objects through image analysis, and more specifically, measuring the actual size of furniture and analyzing space using images taken using a smartphone. This is about a system for correcting distance between objects, length distortion, and drawing through image analysis.

Camera distortion is caused by differences in the refractive index of each color of the lens, spherical aberration, deformation due to lens wear, or optical axis distortion of the camera and lens or individual lenses within the collective lens group.

When distortion occurs in this way, there is a problem that the subject captured by the camera and the image after shooting are different at the pixel level, as shown in Figure 2. As a result, accurate shape information about the subject cannot be obtained, resulting in errors in 3D modeling, etc. .

Conventional distortion correction has been done mathematically using camera coefficients, but this has the problem of low precision because it is processed in a generalized manner rather than the distortion of individual pixels due to the curvature of each lens, chromatic aberration, spherical aberration, etc.

Meanwhile, the above-mentioned background technology is technical information that the inventor possessed for deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be known technology disclosed to the general public before filing the application for the present invention. .
