Embodiment Construction
[0070] In the following, the technical solutions of the present invention will be further described in conjunction with the drawings and specific implementation methods.
[0071] figure 1 It is a schematic flow chart of the robot visual inertial point and line feature positioning method of the present invention. The present invention discloses a robot visual inertia point line feature positioning method, which includes the following steps:
[0072] 1. Obtain a priori three-dimensional map of the current scene, the map is constructed in advance, and the map is required to include the measurement data of the acceleration of gravity in the map coordinate system, which is generally measured by an inertial sensor, specifically when determining the map coordinate system At the same time, the acceleration data measured by the inertial sensor is saved; the three-dimensional map also includes three-dimensional point-line features, so that it can be matched with the two-dimensional poin...
