Abstract: [Purposes] As an important carrier for the digitization of three-dimensional space,traditional panoramic images often suffer from limitations such as uneven exposure,lack of completeness,loss of authenticity,stitching artifacts,and subpar image quality in complex spatial configurations,making it difficult to meet the high-precision,hyper-realistic rendering requirements in high-fidelity digitization contexts. [Methods] This paper proposes a spatial configuration-based method for differentiated acquisition and processing of 720° high-quality panoramic images under multi-spatial scales.The method firstly dynamically plans a differentiated solution for co-optical center and full-view image capture,basing on the spatial geometric features of the scene,and acquires full-frame DSLR image data through continuous multi-stage exposure,secondly gets HDR processing on the image. [Findings] Stitching image with optimizative method on single-platform can generates 720° high-quality panoramic images. [Conclusions] Experimental results demonstrate that this method overcomes the limitations of high dynamic range lighting,improves efficiency,accuracy,and image quality,and is adaptable to various scenarios,while demonstrating enhanced adaptability to diverse spatial configurations such as normal,crowded,and expansive scenarios.
