Non-texture spatial object attitude estimation algorithm based on contour point ORB (Oriented FAST and Rotated BRIEF) feature matching

The invention provides a non-texture spatial object attitude estimation algorithm based on contour point ORB (Oriented FAST and Rotated BRIEF) feature matching, which belongs to the technical field ofdigital image processing. On the basis of three-dimensional model prior, data information contained in the contour of a projected image is made full use of, ORB feature matching and color indexing are used to build a 2D-3D feature corresponding relationship from an input image to an object three-dimensional model, matching errors are used to build a confidence probability matrix, and a weighted orthogonal projection algorithm is put forward to calculate six-degree of freedom attitude parameters of the non-texture spatial object. The ORB features improve the accuracy of contour point matching,and certain robustness is realized in a condition of large offset of an initial attitude relative to a real attitude. The contact between building of the 2D-3D corresponding relationship subproblem and calculation of the attitude parameter subproblem is thoroughly explored, the matching errors are used to build the confidence probability matrix as the prior information for calculating the attitude parameters, the phenomenon that an RANSAC algorithm is used to eliminate error matching points is avoided, and the algorithm calculation efficiency and the precision are improved.

Method for eliminating close-packed stellar field from star catalogue

ActiveCN101236084AImprove uniformityEliminates issues with selecting as a navigation starNavigation by astronomical meansStar sensorPre selection
A method for eliminating dense stellar field in a catalogue of stars comprises (1) selecting n stars with stellar magnitude lower than MT from an astronomical catalogue with gross star number of t to form a pre-selection catalogue of stars, (2) arranging a score counter with initial value of zero for each star in the pre-selection catalogue of stars, (3) selecting a neighborhood omega i of the i star, (4) detecting omega i, when j star exists in omega i and stellar magnitude Mj of the j star is lower than stellar magnitude Mi of the star i, then star i score counter Count i +1, (5), repeating the step (3) and step (4) until all stars in the pre-selection catalogue of stars pass through the same treatment, (6) traversing the pre-selection catalogue of stars, eliminating all stars with score counter larger than zero in the pre-selection catalogue of stars, and forming a navigational catalogue of stars with the rest stars. The method for eliminating dense stellar field in a catalogue of stars resolves the problem that two close stars are both selected as navigational stars, is favorable for increasing the uniformity of navigational stars distributed in the whole celestial sphere, and favorable for increasing star identification probability of star sensor.
