2results about How to "Realize the navigation function" patented technology

The application provides a kind of indoor global vision-based unmanned vehicle positioning method and device, the method comprises: step 1, visual sensor is fixed on indoor ceiling, and the ground environment image of the periphery of mobile robot in running is collected;Two two-dimensional code labels are arranged on the top of the mobile robot, and the mobile robot is identified by two two-dimensional codes;Step 2, the ground environment image obtained in step 1 is transformed by image processor Abnormal image is obtained by distortion correction;Step 3, the normal image is extracted to obtain feature points;More than two normal images with feature points captured by different vision sensors are matched;Step 4, the image is fused to obtain the wide-area panoramic image after splicing;Step 5, the pose information of the mobile robot is solved.The application can realize the control and tracking of mobile robot in wide-area complex indoor environment, and realize the accurate navigation of mobile robot.

The embodiment of the invention provides a rendering method and device, electronic equipment and a storage medium, and relates to the technical field of computers. The method comprises the following steps: displaying a current picture frame in response to a triggering operation for a navigation function; obtaining equipment performance parameters of the terminal equipment, if it is detected that the equipment performance parameters of the terminal equipment are reduced, reducing the model precision of an LOD model, and taking the LOD model with the reduced model precision as a target LOD model; and rendering a next picture frame of the current picture frame based on the target LOD model. According to the embodiment of the invention, the model precision of the LOD model is adaptively adjusted according to the equipment performance of the terminal equipment, so that the navigation function can be realized on the terminal equipment with different performances.
