摘要：
The present invention relates to a camera correction method and system applicable to an X-ray machine, in which a correction board is formed with a regularized correction pattern of an anti-X-ray layer. An X-ray camera and a regular camera respectively captures an image of the correction pattern in order to compute internal and external parameters of the X-ray camera and the regular camera on the same coordinate system. A host device is used to calculate a physical space conversion relationship between each captured image and the correction pattern. With the correction pattern being clearly visible under the radiation of the X-ray camera, correction of the X-ray machine can be performed through image capture and calculation of parameters so as to overcome the problems of the conventional correction devices of which the manufacture is complicated, having a great error, and being incapable of simultaneously correcting multiple X-ray machines.本發明係一種適用於X光機之相機校正方法與系統,主要係於一校正板上形成一抗X光層的規則化校正圖案,由一X光相機與一傳統相機分別擷取該校正圖案的影像,據以在相同座標系統中分別計算X光相機與傳統相機的內外部參數,再由一主機將分別擷取之影像與校正圖案計算相互間的實體空間轉換關係;利用校正板上之校正圖案於X光相機照射下清晰可見的原理,以影像擷取與參數計算的方式進行X光機的校正,解決現有使用校正器具有製作複雜、誤差大與無法同時校正多台X光機的問題。10‧‧‧X光機11‧‧‧X光發射器12‧‧‧X光相機13‧‧‧傳統相機20‧‧‧主機201、202‧‧‧顯示器21‧‧‧相機校正模組30‧‧‧銅箔電路板
