Abstract

The invention discloses an intelligent machine attitude matrix calculating method and a method applied to photogrammetry. The intelligent machine attitude matrix calculating method mainly comprises the following steps that an intelligent machine measures the components ax, ay and az of gravitational acceleration at three directions x, y and z of the intelligent machine; the intelligent machine acquires the azimuth angle phi; and the attitude matrix Rg is calculated according to the description. According to the invention, the attitude of a camera on the intelligent machine can be obtained by the attitude matrix Rg of the intelligent machine, and the intelligent machine attitude matrix calculating method and the method applied to photogrammetry can be applied to the fields of photogrammetry, panorama measurement, computer vision, LBS service, virtual reality simulation, attitude measurement reinforcement of wearable equipment and the like.

Description

technical field

[0001] The invention relates to the field of information technology, in particular to a calculation method for an attitude matrix of an intelligent machine and a single-eye and multi-eye vision positioning method for a camera. Background technique

[0002] The attitude measurement of smart machines and their cameras is of great significance. Computer vision, photogrammetry, and other engineering surveys are in urgent need of a cheap, lightweight attitude measurement equipment to determine their attitude.

[0003] Since the attitude of the smart machine is different, the real scene seen at the same position is different. The accuracy of the attitude of the smart machine affects the navigation accuracy, photogrammetry accuracy, 3D simulation accuracy and augmented reality information superposition accuracy, so the accurate determination of the smart machine attitude is of great significance .

[0004] The traditional intelligent machine attitude measurement ma...
