The positioning system further comprises a fourth base station, wherein the fourth base station is provided with a support, a transverse laser ranging device and a longitudinal laser ranging device, the transverse laser ranging device and the longitudinal laser ranging device are arranged on the support and are arranged vertically, after the step B, the fourth base station is sequentially placed at an obstacle in a measuring area, and coordinates of the second base station and the third base station which are moved transversely and longitudinally and matched with the fourth base station to measure the obstacle are transmitted to an upper computer; and C, generating coordinates of the obstacle avoiding position when the road surface test target point is generated. The indoor ground light measurement method can automatically measure the coordinate information of the area to be measured in the environment without satellite navigation and realize automatic navigation measurement of the illumination data of the road surface test target point. The device can be applied to the illumination measurement of spaces such as tunnels and basements, and can avoid obstacles such as fixed pillars, pits on the ground, tables and the like.

Further, the positioning system further comprises a second mobile photometric measurement vehicle and a second mobile tag arranged on the second mobile photometric measurement vehicle, and the second mobile photometric measurement vehicle and the first mobile photometric measurement vehicle are used for simultaneous measurement. The indoor floor luminosity measurement method can be used for simultaneously using two mobile luminosity measurement vehicles to carry out measurement, so that the measurement efficiency is improved.

in conclusion, the present invention has the above-mentioned excellent characteristics, so that it can be used to enhance the performance of the prior art and has practicability, and becomes a product with practical value.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
