基于Harris算法的图像角度计算方法
Image Angle Calculation Method Based on Harris Algorithm
摘要
Abstract
For the problem of corner detection at L-junction in image and calculate the corner angle at L-junction, this paper proposes a new algorithm based on improved Harris to detect the corner at L-junction and calculate the corner angle at L-junction. The algorithm calculates the sum of the weight on each edge in differential coefficients window, and takes the average value of all the differential coefficients as the representative differential coefficient, and measures the principal curvature on the detected corners and through the ratio influence function identify the corner at l-junction. According to the calculated values of the response function from the above two steps, it calculates the corner angle at L-junction. Experimental results show that angle calculation algorithm based on Harris corner detection improves recognition accuracy rate from 24.6%to 3.3%, and calculates the corner angle at L-junction rate from 10.21%to 3.82%.关键词
