Abstract

The invention discloses an image identification-based round log counting method, in particular to a method for performing round log quantity statistics according to a multi-threshold segmentation result of an image, and belongs to the technical field of image processing. The method comprises the steps of extracting a background region from a preprocessed image firstly, then performing binarization on the preprocessed image by adopting a multi-thread segmentation method, and extracting an alternative round log region by adopting a linear segment and connected region search method; and processing the extracted alternative round log region by utilizing threshold segmentation, morphological operation and the like, finally extracting a connected region center which meets a round log condition, and performing counting. The method has low requirement on the round log shape, effectively solves the problems of non-uniform light conditions of outdoor shooting and the like, and has relatively high practicality and reliability.

Description

technical field

[0001] The invention belongs to the technical field of image processing, and in particular relates to a log counting method based on image recognition, in particular to a method for segmenting log regions by using multiple thresholds to count the number of logs. Background technique

[0002] At present, in the process of timber transportation, the way of inspection and inspection of timber loaded on vehicles is mainly manual, which is labor-intensive, low-efficiency, and error-prone. Therefore, more and more researches have been done on the automatic identification of wood counting.

[0003] The wood recognition method based on image recognition is mainly a method to obtain the number of wood by processing the images of neatly arranged wood. Wood counting mainly involves steps such as wood image acquisition, wood image processing, wood area segmentation, and wood clustering.

[0004] At present, there are mainly the following methods for log counting: 1. Th...
