The invention provides an object identifying and positioning method in refrigeration equipment. The first image of a first camera and the second image of a second camera are acquired; the four cornersof a shelf are calibrated and the first image coordinates and the second image coordinates are determined; the world coordinates of the corners are calculated; the first mapping relation and the second mapping relation are calculated; and the type of the target object in the first image and the second image is identified and the first target plane coordinates and the second target plane coordinates of the target object are calibrated, the first target plane coordinates and the first mapping relation are called to calculate first reduction world coordinates and the second target plane coordinates and the second mapping relation are called to calculate second reduction world coordinates. Whether the deviation of the first reduction world coordinates and the second reduction world coordinates belongs to the preset interval is compared and judged, the target object type and the identification number are outputted if the judgment result is yes, or the target object type and the correctionnumber are outputted. The invention also discloses the refrigeration equipment. The object identifying and positioning method in the refrigeration equipment has the advantages of high precision and high intelligent degree.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a method for identifying and locating items in refrigeration equipment and a refrigeration equipment. Background technique [0002] With the improvement of living standards, people pay more and more attention to nutrition and health. Smart refrigeration equipment can recommend recipes for users by identifying the food stored in the compartment, count the quantity and type of food, and facilitate people's lives. In order to realize the above functions, the intelligent identification of food is the basis, and it is particularly important to accurately identify the type and quantity of food. [0003] In the prior art, two schemes are used to realize food recognition. The first scheme is a single RGB wide-angle camera plus supplementary light. Install a fill light on the other side. This method cannot overcome the problem that the food is partially or completely oc...
