Problems solved by technology
[0003] At present, when the building close-range photogrammetry device collects road information, it usually records the road information through the camera body fixed on the top of the mobile car. However, the camera body is relatively fixed and can only perform rough measurement of road surface information. Recording, some corners are likely to cause omissions or unclear shooting, resulting in inaccurate measurement and recording results
[0004] Regarding the related technologies mentioned above, the inventor believes that there is a defect that the measurement record results of the architectural close-range photogrammetry device are inaccurate

The invention relates to a building close-range photogrammetry device and method, and relates to the field of road measurement. The photogrammetry device comprises a moving trolley, a supporting plate detachably connected to the upper portion of the top of the moving trolley, a supporting sleeve fixedly arranged on the upper portion of the supporting plate, a lifting sleeve slidably connected to the upper portion of the supporting sleeve, a supporting frame rotationally connected to the upper portion of the supporting sleeve along the vertical axis, a photographic device body rotationally connected to the upper portion of the supporting frame along the horizontal axis, a lifting mechanism arranged between the lifting sleeve and the supporting sleeve and used for controlling the lifting sleeve to ascend and descend, a horizontal rotating mechanism arranged between the lifting sleeve and the supporting frame and used for controlling the supporting frame to rotate, and a vertical rotating mechanism arranged between the support frame and the photographic device body and used for controlling the photographic device body to rotate. The building close-range photogrammetry device has the effect of improving the accuracy of the measurement recording result of the building close-range photogrammetry device.
Description
technical field [0001] The present application relates to the field of road surveying, in particular to an architectural close-range photogrammetry device and method. Background technique [0002] With the large-scale construction of buildings and the improvement of roads in our country, in order to collect road information, the road information is usually measured and recorded by building close-range photogrammetry devices. [0003] At present, when the building close-range photogrammetry device collects road information, it usually records the road information through the camera body fixed on the top of the mobile car. However, the camera body is relatively fixed and can only perform rough measurement of road surface information. Recording, some corners are likely to cause omissions or unclear shooting, resulting in inaccurate measurement and recording results. [0004] With regard to the related technologies mentioned above, the inventor believes that there is a defect t...
