With the current regulations of Taiwan. The tire tire tread depth can not be less than 1.6mm. Low tire tread depth will greatly increase the probability of traffic accidents. The current detection method is mostly visual or single-point measurement. It is difficult to accurately measure the depth of tread. So we invented this instrument. Which can be more accurate and fast related of the detection.
The instrument is equipped with a space inside. The top and side of the instrument are mounted with a linear laser scanner and a monochrome camera. then use software controls the side camera to took a picture of the linear laser scan light image on the tread of tire. Decide linear laser between the lowest and the highest line pixel difference of the image.Build the conversion formula to get the tread depth of the tires.

本專利使用雷射掃描光源對胎紋截面進行線性檢測，有別於市場相關產品僅以單點進行量測，不但提升胎紋量測準確度，更有效提高工作效率。

透過儀器的介入，不僅縮短檢驗時間更減少人為量測的誤差，如此一來，除保障乘客之安全性，更能提供其他用路人一個安全的道路使用環境。
