[0027] See also Figure 6 The implementation steps of the item storage location management setting are:
[0028] 1. Collect the appearance images of all items and extract the features of the item images through the feature extractor. Since the ORB (Oriented FAST and Rotated BRIEF) algorithm has good robustness to changes in scale, rotation, illumination, etc., it can adapt to a variety of scenarios and conditions. It has good robustness in practical applications and fast calculation speed, and is suitable for real-time image processing and machine vision applications. Therefore, we use the ORB detection algorithm to extract features, and establish a database by combining the feature extraction results with their corresponding storage location information. It can be expressed as:
[0029] Item A:
[0030] Where F is the set of feature points extracted from the item, L is the storage location coordinates of the item, such as L (warehouse No. 1, shelf No. 2, floor 3, ...), and the constructed database is stored in the data storage device.
[0031] 2. The image collector 8 obtains the image of the object to be stored, and the feature extractor uses the ORB detection algorithm to extract the feature information of the object and establish a feature point set of the object.
[0032] 3. The computer matches these feature points with the features stored in the database one by one and calculates the Hamming distance of each pair of feature points.
[0033] 4. Result output: If the calculated Hamming distance is less than the set threshold λ1, it is considered that the two feature points are matched successfully. If there are more than λ2 feature points in the feature point set of an object in the database that satisfy the Hamming distance less than the threshold λ1, the computer displays the location information of the object.
