Photograph Method Used in Computerized Log Centering

Photograph method is a new scanning technique that provides cost-efficient and accurate computer system for log centering. A monochrome video camera is used to document images of a log in a perimeters rotation time. 3D digital contour of the log is constructed with the images. The biggest internal cylinder is calculated in software modules. Experiments in present study proved that photograph method was quite feasible in optimizing log centering with higher accuracy. The cost-efficient near-infrared images used in the devices were able to avoid the impact of changing illumination. This centering system can be utilized in small and medium enterprises.
