An Improved 3D Shape Recognition Method Based on Panoramic View

Figure 2

Illustration of the panoramic view construction process. In this figure, p₁ is the center point of the corresponding grid, q₁ is the point on the z-axis at the same height as p₁, t₁ is the intersection of the ray drawn from q₁ and the model surface, and d₁ represents the distance between q₁ and t₁. The geometric meanings of q₂, p₂, t₂, and d₂ are similar to q₁, p₁, t₁, and d₁, respectively.
