This invention relates to a laser-based inertial real-time dynamic object removal SLAM system, specifically for robotic SLAM. Addressing the issue in existing technologies where dynamic objects are not removed before pose estimation, leading to inaccurate pose output, this application removes dynamic objects first, followed by feature matching for localization. This solves the problem of afterimages left by dynamic objects during mapping in laser SLAM systems, reducing the impact of dynamic objects on localization accuracy and improving the accuracy of localization and mapping. This application uses a vertical voxel height descriptor to describe the occupancy of dynamic objects and uses IMU pre-integration as the initial pose estimate to prioritize the removal of dynamic objects. Then, a weighted optimization strategy is employed to obtain the optimal pose estimate, mitigating the influence of dynamic objects and improving the accuracy of pose output.

This invention relates to the field of electronic paper display control technology, specifically to a dynamic refresh scheduling method for e-ink screens based on ambient light sensing. The method first collects the ambient light illuminance time series and aligns it with the grayscale matrices of preceding and following frames by timestamp to form a scene data package. Second, based on the factory grayscale-reflectance calibration data of the e-ink screen and the electrophoretic particle residue coefficient, it estimates the afterimage reflectance difference map according to pixel position. Then, based on the segmentation rules of human eye contrast perception, it constructs a perception threshold map that adapts to ambient light. Finally, it generates a pixel-level visibility classification map by calculating the ratio of afterimage brightness difference to the perception threshold. Finally, it combines ambient light temporal situation identification to jointly generate a refresh decision command including refresh mode, refresh area, and refresh timing. This invention ensures that the refresh decision is consistent with the user's actual visual visibility in outdoor reading scenarios, alleviating the problems of missed afterimage detection and ineffective full-screen flicker at illuminance boundaries under strong sunlight.
