Abstract

To improve the recognition accuracy of the embedded visual module and make it competent for visual tasks on complex occasions, an image preprocessing method used on the OpenMV is proposed. Aiming at the two main recognition tasks of machine vision, color recognition and shape recognition, an image preprocessing algorithm and a filtering algorithm based on the OpenMV of embedded vision module are proposed for use by analyzing the interference existing in practical problems. For color features, the processing of binary segmentation and image morphology can filter the background and the noise similar to the target, which greatly improves the recognition accuracy with only a small increase in recognition time. For shape features, kernel filtering and Hough Transform are used to filter the irrelevant targets in the image, which improves the recognition accuracy, reduces the image complexity, and speeds up the operation speed of Hough Transform. The experimental and practical results show that the image preprocessing method combined with OpenMV can not only take into account the advantages of the embedded visual module but also complete the task of target recognition with high accuracy, which helps meet the needs of practical engineering and promote the wide application of embedded vision.
