QUALITY INSPECTION OF SATELLITE IMAGERY BLOCK ADJUSTMENT WITHOUT GCP

Zhao, Y.; Zhao, H. T.; Guo, J.; Tu, H. J.; Yin, S.

The current status of insufficient research on production technology and quality inspection methods for uncontrolled mapping of block adjustment results for global project. This paper proposes a set of quality inspection process and technical methods for large-scale production, lack of field checkpoints and difficult to verify in the field based on the analysis of the characteristics of the results: First, analyze the quality elements and inspection contents to be inspected, determine the inspection methods for different inspection contents; Then, extract items that can be automatically checked or need to be verified the production process data, establish inspection rules, implement batch automatic inspection and production data verification for some check items; study the inspection methods for the remaining items and implement human-computer interaction check. Finally, 4 test-fields were checked and the results showed that the technical route proposed in this paper is feasible, and the quality evaluation results are objective and reliable.
