Embodiment Construction
[0035] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described. Apparently, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0036] like figure 1 As shown, point P is the point to be measured, and its coordinates are (X, Y, Z), but it is difficult or impossible to realize the vertical position of the prism, and the method of tilting the prism is used for measurement. Fix the prism on the top of the support rod, fix the bottom of the support rod on the point to be measured, take the bottom of the support rod as the center of the circle, place the support rod obliquely to four different tilt positions, and get the prism at four different tilt positions The coordinates of P1(X ...

The invention discloses a special measuring method for an inclined prism, and belongs to the technical field of surveying and mapping. The prism is obliquely placed; the coordinates of the prism in different inclined positions are measured; an equation set between the coordinates of the prism and the coordinates of a to-be-measured point is established; and the equation set is solved to obtain thecoordinates of the to-be-measured point, thereby solving the point location measurement precision problem that prism leveling cannot be performed due to field condition limitation. According to the method, computer calculation is realized through programming; written measurement software is installed in a total station or a mobile terminal; the coordinates of the to-be-measured point can be obtained by inputting the coordinates of the prism in the different inclined positions to the measurement software for calculation; real-time calculation of the coordinates of the to-be-measured point, andreal-time data display are realized; the calculation speed is high; and the precision is reliable. In the measuring process, the pole bottom of the prism only needs to be placed on the to-be-measuredpoint and the prism does not need to be leveled, so that the operation can be carried out by non-professionals, the investment of measuring professionals is reduced, the working efficiency is improved, and the investment cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of surveying and mapping, and in particular relates to a special measurement method for an inclined prism. Background technique [0002] When collecting measurement data in the field, the traditional total station is combined with the prism measurement method. The forward-looking prism needs to be strictly leveled to correctly obtain the coordinates of the points to be measured, and the erection and leveling of the prism requires trained professionals. to operate. If some corners of buildings need to be measured during the measurement process, the forward-looking prism cannot be leveled due to conditions, and the total station is used for measurement without prism, and the accuracy cannot meet the accuracy requirements. Contents of the invention [0003] The purpose of the present invention is to provide a special measurement method for inclined prisms, which solves the problem of point measurement accura...
