Abstract

The invention discloses a method for recovering a monocular SLAM scale through detection and calibration, and the method comprises the steps: calibrating a camera, obtaining a first depth from a pointto the camera on a visual plane by perspective transformation calculation, detecting and setting a Marker, and detecting and setting a second depth from the Marker to the camera through a deep learning module; adding the first depth and the second depth into the SLAM back-end optimization process to obtain the monocular SLAM scale, so that the monocular SLAM scale is recovered, the calculation process is effectively simplified, and the algorithm complexity and related calculation amount are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method for recovering the monocular SLAM scale through detection and calibration. Background technique [0002] A monocular camera will lose a dimension when taking photos, and the scale can be restored by the height of the camera and the information of the road. The traditional scheme of restoring the scale of monocular SLAM relies on the accuracy of road sign recognition and road geometric model calculation, which is complex and computationally intensive. Contents of the invention [0003] In view of the above problems, the present invention proposes a method for recovering the monocular SLAM scale through detection and calibration. [0004] In order to achieve the purpose of the present invention, a method for recovering the monocular SLAM scale through detection and calibration is provided, including the following steps: [0005] S10, by calibrating the camera a...
