Embodiment Construction
[0015] The blind spot coordinate positioning method that cannot place GPS is different from the prior art, and has been greatly improved, specifically:
[0016] 1) if figure 1 As shown, a fixed-length ranging pole (2) equipped with an inclination sensor (3) is placed on the point to be measured where GPS cannot be placed, and a GPS antenna head (1) is provided on one end of the ranging pole, wherein the MEMS The sensor can measure the azimuth angle of the distance measuring rod in the projection direction and the vertical angle of the rod in the vertical direction under any posture. The length of the distance measuring rod is a fixed value L. The GPS antenna head and the rod end use a universal connector Connection, can be fixed in any orientation.
[0017] 2) When measuring, first place the non-GPS end of the distance measuring rod on the point to be measured, and fix the length of the rod, then turn on the GPS receiver to enter the coordinate positioning state, and quickly ...

The invention discloses a method positioning coordinates of a GPS-unmountable blind spots. A telescopic distance measurement rod with an MESM sensor is arranged on a GPS-unmountable spot to be measured, and a GPS antenna head capable of rotating by any angle is arranged at one end of the distance measurement rod; the attitude is regulated and kept unfixed, coordinates of the position where the GPS antenna head is located are obtained by a GPS receiver, and the azimuth angle, vertical angle and rod length of the distance measurement rod are recorded, and then the coordinates of the spot to be measured are calculated by virtue of a coordinate measurement formula. According to the method, problems about the measurement of coordinates of the blind spots under a blocked condition are better solved.
Description
1. Technical field [0001] The invention relates to a method for measuring point coordinates, in particular to a blind spot coordinate positioning method in which GPS cannot be arranged. 2. Technical background [0002] So far, the method of measuring point coordinates mainly adopts theodolite and tape measure, total station measurement, GPS static measurement and RTK dynamic measurement and other methods, but in the actual operation process of field measurement, the above methods have many troubles and inconveniences: [0003] ①Using theodolite, tape measure and total station to measure point coordinates requires a relatively flat ground and good visibility conditions, and the measurement work cannot be carried out under the condition of no visibility. [0004] ②Using satellite positioning measurement coordinate methods such as GPS static measurement and RTK dynamic measurement requires that the upper part of the antenna head is unobstructed and has a sufficient signal recei...
