Nowadays, with the significant application of remote sensing satellite in military and civil use, how to intelligentize space devices and materials has become a huge challenge.
Traditional retrieval methods usually focus on the optical properties of the devices and materials and lack in semantic description.
Traditional text-based methods, which are based on optical properties of these devices and materials, usually retrieve abundant useless data.
Summary In this paper, we have built a metadata ontology for the satellite devices and materials and performed semantic query on the inference model.

The result show that at different brightness the retroreflective light present unlike spectrum distribution, and white, blue material with higher retroreflection value under mesopic vision, red material own lower value, this phenomenon is more apparent with the decrease of brightness.
Introduction With the increasing attention on safety and security, retroreflective materials are used more widely in traffic, vehicle and so on.
According to CIE 54.2-2001[1], JT/T 690-2007[2] and other national/foreign standards or technical reports, the coefficient of retroreflection of materials were recognized as the most important parameter.
