Abstract In order to optimize the wood internal quality detection and evaluation system and improve the comprehensive
utilization rate of wood, this paper invented a set of log internal defect detection and visualization system by using
the ultrasonic dry coupling agent method. The detection and visualization analysis of internal log defects were
realized through log specimen test. The main conclusions show that the accuracy, reliability and practicability
of the system for detecting the internal defects of log specimens have been effectively verified. The system can
make the edge of the detected image smooth by interpolation algorithm, and the edge detection algorithm… More >
