Problems solved by technology

[0003] Most mobile devices (such as mobile phones, glasses, tablet computers, etc.) have cheap cameras and sensors, and there is a time offset between the camera and the sensor, and the time offset between the camera and the sensor is dynamically changed (such as every time Restart the camera or sensor, or change dynamically over time), therefore, this poses a great challenge to real-time positioning using the combination of cameras and sensors

Abstract

The present disclosure relates to an information processing method, device, electronic device and storage medium. The method includes: acquiring the acquisition time of a first image frame currently to be processed; according to time offset information currently calibrated for the first image frame , correct the acquisition time of the first image frame to obtain the calibration time of the first image frame; based on the inertial sensing information obtained at the calibration time and the first image frame, locate the current position . In the embodiment of the present disclosure, the acquisition time of the first image frame can be calibrated to improve the accuracy of the positioning result.

Description

technical field [0001] The present disclosure relates to the technical field of visual inertial navigation, and in particular, to an information processing method, apparatus, electronic device and storage medium. Background technique [0002] Obtaining the 6DOF spatial position of the camera in real time is a core fundamental problem in the fields of augmented reality, virtual reality, robotics, and autonomous driving. Multi-sensor fusion is an effective way to improve spatial positioning accuracy and algorithm robustness. The time offset calibration between sensors is the basis for realizing multi-sensor fusion. [0003] Most mobile devices (such as mobile phones, glasses, tablet computers, etc.) have cheap cameras and sensors, there is a time offset between the camera and the sensor, and the time offset between the camera and the sensor changes dynamically (such as each time restarting the camera or sensor, or changing dynamically over time), therefore, it is a great cha...
