Experiments show that the method has a good performance in pin defect detection in UAV patrol image on test set. Compared with other prevailing object detection methods, the detection effect is better and the generalization ability is stronger.

2017年5月31日 · The pin defect inspection is a challenging problem due to the complex background. In our work, we propose a method for this purpose based on Circle Hough Transform to clip and resize to enhance images, and cascade classifier training and cascade classifier intersection to detect pin defect.

2019年5月8日 · We have proposed a convolutional neural network (CNN) architecture–based supervised technique along with two unsupervised techniques based on depth map and texture of pins to identify bent and corroded pins respectively …

3 天之前 · The cotter pin is a critical component in power transmission lines, as it prevents the loosening or detachment of nuts at essential locations. Therefore, detecting defects in cotter pins is vital for monitoring and diagnosing faults in power transmission systems. Due to environmental factors and human errors, cotter pins are susceptible …

In order to solve the problems in manual detection of LQFP chip defects, an automatic detection system of LQFP chip pin defects based on machine vision is designed. The system can use ARM-DSP dual-core architecture to rapidly realize image acquisition, processing, feature extraction and peripheral applications.

In this paper, we will focus on defect inspection by using adaptive boosting with Local Binary Pattern (LBP) feature. Our approach consists of two parts, analysis and detection. Since pins are physically on Printed Circuit Board (PCB), in different images, pins may not locate at the same location and have different values in x, y axes.
