Visual positioning method and device based on local variance and posterior probability classifier
ActiveCN114708420Bavoid wastingimprove accuracyCharacter and pattern recognitionEngineeringPosteriori probability
The present application provides a visual positioning method and device based on local variance and posterior probability classifier. The present application uses two sliding windows with different moving steps in the definition process and the retrieval process, that is, to reduce the amount of calculation in the retrieval process, and also to avoid the sliding window in the retrieval process from making incorrect window judgments due to excessive moving steps when passing through the posterior probability classifier. On the one hand, it reduces the requirements for system calculations and improves matching efficiency. On the other hand, the definition part also takes into account the multi-scale situation to generate a multi-scale sliding window. Moreover, since the multi-scale sliding window in the retrieval part is performed after the initial scale sliding window is traversed, it avoids wasting too much calculation when the target object is not scaled. This method further improves the matching efficiency, and at the same time overcomes the shortcomings of excessive calculation and invalid calculation in the matching process of the prior art, and improves the accuracy of template matching.
