2results about How to "Eliminate false detections" patented technology

This invention relates to the field of industrial visual intelligent inspection technology, and in particular to an intelligent visual inspection system for surface defects of label paper. The system continuously acquires multiple frames of images of the same label area during roll-to-roll feeding, establishes spatial correspondence between adjacent frames, and calculates the time-series changes in grayscale distribution, edge position, and texture features of the divided structural regions. Through continuous discrimination, progressively changing areas are identified as process evolution areas. Areas that do not meet the continuous change pattern are anomaly screened and defect identification signals are generated. This solution changes the processing method based on single-frame matching tolerance for defect judgment, maintaining anomaly identification stability under tension fluctuations or local deformation conditions, and is suitable for detecting surface defects of various types of labels.

This application relates to the field of vehicle intelligent control technology, and provides an obstacle detection method, a self-moving device, and a storage medium. The method includes: acquiring obstacle detection information collected by each ultrasonic sensor in an ultrasonic sensor group fixedly mounted on the self-moving device; wherein the ultrasonic sensor group includes a vertically mounted high-mounted ultrasonic sensor and a low-mounted ultrasonic sensor, with the first landing point of the detection range of the high-mounted ultrasonic sensor coinciding with the second landing point of the detection range of the low-mounted ultrasonic sensor; and determining target obstacles around the self-moving device and their target location information based on the obstacle detection information. In this application, by installing an ultrasonic sensor group on the self-moving device, obstacles within the radar perception blind zone can be detected through the ultrasonic sensor group, thereby ensuring the movement safety of the self-moving device.
