AI Technical Summary
In existing technologies, the image acquisition time of ultra-generalized stereo image pairs is uncertain, which makes fitting difficult. Differences in the representation and accuracy of imaging geometric model parameters lead to inaccurate light sample mapping direction and deviations in geometric constraints, making it difficult to achieve effective four-dimensional spatiotemporal field reconstruction.
A four-dimensional spatiotemporal field reconstruction method based on phase-shift time coding and imaging spatial consistency is adopted. By constructing a spatiotemporal field function, the imaging geometric model parameters are optimized, the imaging geometric model is unified, the spatiotemporal representation complexity of the scene is reduced, and the temporal correlation and spatial mapping deviation between images are resolved.
It realizes the four-dimensional spatiotemporal field reconstruction of time-varying scenes, reduces the complexity of scene spatiotemporal representation, optimizes the temporal correlation and spatial mapping between images, and improves the accuracy of geometric constraints of light samples.
