ささくれ傷を検出する自動体育館床面検査装置の開発

抄録

Gymnasiums are daily inspected but small wood splinters from the floor are often overlooked because these wood splinters are very small compared to gymnasium floor. Those wood splinters occasionally cause serious accidents. Currently, gymnasiums are inspected visually but it costs a lot of people or time or both. The purpose of this research is developing equipment which inspects the gymnasium floor in a short time, with a small number of people, with low inspection omissions. In order to accomplish these goals, combination of rectangular scan and sub goals is adopted. The result of the running test through the gymnasium (range of depth 37 meters width 27 meters) is as follows. First, total inspection time was 87 minutes. Second, operation required one person when setting and no person when running. Third, inspection omission was at most 2.4%. In the future, to shorten the time, we will stabilize at high speed driving and optimize localization system.
