Abstract

The invention discloses an automatic navigation method and device. The method comprises the following steps of: acquiring a scene video of a current geographical location photographed by a multi-objective camera system; calculating a spatial position and gesture information of the camera in the multi-objective camera system; performing time correlation three-dimensional matching on continuous two-frame images at the same camera time to generate a first environmental object depth map; performing spatial correlation three-dimensional matching on continuous two-frame images at different camera times to generate a second environmental object depth map; constructing a local obstacle map according to the first environmental object depth map and the second environmental object depth map; and mapping the local obstacle map to a safe distance space to determine a safety path from a current position to a predetermined target. The method effectively solves limitation of a conventional depth algorithm in viewing angel and movement, can perform self-position positioning, obstacle sensing and automatic generation of the safety path, is high in positioning precision and optimum in safety path, and can be applied to mobile platforms such as robots or entertainment unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to an automatic navigation method and device. Background technique [0002] With the rapid development of product technology such as drones, robots, and unmanned vehicles, the demand for navigation systems and methods has also increased significantly. Automatic navigation means that the moving body makes global path planning based on the known map information according to the predetermined task command, and constantly perceives the surrounding local environmental information, makes various decisions, and adjusts its own position at any time. Posture and position, guide yourself to move safely to the target position. Existing automatic navigation methods or systems mainly include two methods based on positioning and tracking technology. The automatic navigation method of positioning is relatively more intelligent, and there are many applications in the market, such as GPS, ...
