The invention discloses an AR home experience method in a large scene. On the basis of combination of a natural feature identification-based three-dimensional registration method and a binocular tracking positioning and local mapping method, the camera attitude is estimated by using feature points of a real-time scene and corresponding three-dimensional points thereof under the binocular trackingpositioning and local map construction technology. According to the mode, on-site environment features shot in real time are used as recognition tracking objects, a virtual home model can still be normally positioned and tracked under the condition that no identification graph exists, the problems that an existing AR home experience application is small in use range and poor in stability are solved, and therefore the AR home experience of virtual and real fusion can be met in a wider range and more truly.

The invention discloses an omnidirectional fisheye image feature tracking and extracting method based on a non-parallel virtual binocular, and the method comprises the steps: constructing a four-eye fisheye camera system, obtaining the relative pose transformation based on a pre-calibration external parameter, predicting the pose based on a uniform speed model or IMU pre-integration, and constructing a re-projection error function through common-view feature points. According to the invention, by constructing four groups of virtual binocular combinations, on the premise of not increasing the number of physical cameras, eight-view-angle equivalent coverage is realized, so that a high-overlapping common-view area is formed between adjacent cameras; on the basis of a pre-calibrated external parameter and an MEI fisheye model, a spherical epipolar line is directly generated for a distorted image to carry out matching search, and meanwhile, a time sequence-space two-dimensional fault-tolerant mechanism is put forward for challenges of shielding and environmental interference: according to a dynamic direction switching design, when a tracking feature number is lower than a threshold value due to shielding in a camera direction, the tracking feature number is smaller than the threshold value; the camera direction is actively switched to serve as a main tracking source, new feature points are supplemented at the same time, and system collapse caused by local view failure is avoided.

The invention discloses a watermark embedding and detecting method and system based on a large model. The method comprises the following steps: acquiring a real text sequence of a watermark to be embedded; constructing a watermark embedding and detecting model based on a large model; and completing watermark embedding and detection of a real text sequence by using the watermark embedding and detection model. According to the method, the watermark is directly embedded in the model training process, and the detection mechanism is optimized, so that efficient embedding and accurate detection of the watermark are realized. A generative adversarial network and a binocular telescope structure are innovatively introduced, so that the natural fluency of a generated text is ensured, and the robustness of a watermark under adversarial attack and natural rewriting is remarkably enhanced. Meanwhile, the calculation cost is reduced by adopting a low-rank adapter technology, so that the method can be widely applied to various pre-training large models and has very high adaptability.

The present invention discloses a method for verifying the volume of a coal pile based on a single two-dimensional image of a coal yard, which relates to the technical field of coal yard management and solves the technical problem of low coal counting efficiency based on computer vision measurement technology. The key point of its technical solution is to train multiple coal pile photos to achieve the effect of directly verifying the volume of the coal pile through only a single image without depth of field in the subsequent algorithm implementation process, thereby ensuring real-time performance. In this process, the image only requires a monocular camera to be taken, and there is no need to purchase multiple large-scale equipment such as binoculars, depth of field cameras or laser coal counting meters, which ensures that the algorithm achieves the economic goal. Finally, the purpose of verifying the volume of the coal pile more accurately and quickly is achieved by designing an algorithm framework. The present invention realizes the verification of the volume of the coal pile in the coal yard only through a single two-dimensional image, thereby reliably counting the coal, with low cost, convenience and speed, and can realize real-time monitoring of the coal yard.
