Abstract: In view of the complex topography, fragmented land parcels, irregular shape of rural house bases, and the fact that most houses are in places with high and dense vegetation, the field operation is difficult and time-consuming and the signal of conventional RTK will be interrupted in the application, etc. This paper considers the advantages of oblique photogrammetry technology and inertial guidance RTK, and proposes a method of using the two measurements technology in rural homestead, aiming to solve the work of confirmation of rural homestead right in Guizhou province in an efficient way. In this paper, the experiment of confirmation of rural homestead right is carried out in Xinhua village, Dongdi township, Nayong county, Guizhou province, and the total station is used to observe the location of boundary points, boundary line and parcel areas in the study area with high accuracy, and the feasibility of the proposed method is elaborated from the following two perspectives. Firstly, the data obtained by using total station data and the graphical interpretation method of oblique photogrammetry technology are compared and analyzed statistically. Secondly, the data obtained by using total station data and the data obtained from the total station data and the inertial guidance RTK analysis method are compared and analyzed. The experimental results show that the results of the oblique photogrammetry graphical method meet the requirements of the graphical method 1∶1000 cadastral map in Regulations for Cadastral Survey in TD/T 1001—2012, and the results of the inertial guidance RTK analytic method meet the requirements of the analytic method secondary accuracy. Based on this, the method proposed in this paper shows advantages of good accuracy, high operability and low time consumption in confirmation of rural homestead right, and can provide a replicable reference method for confirmation of rural homestead right in complex area.

Key words: confirmation of rural homestead right, oblique photogrammetry, inertial guidance RTK, Guizhou province, regulations for cadastral survey
