Description
Technical Field
The utility model relates to a location ball target fixing device.
Background
Today that surveying and mapping technique is perfect day by day, emerging three-dimensional laser scanning measurement is entering the survey and drawing field secretly, in building deformation monitoring, three-dimensional laser scanning passes through certain frequency transmission laser signal, meet the obstacle and can reflect the acceptance device who feeds back to three-dimensional scanner when the signal, every second scanner will scan million rank's point cloud, 360 all standing, carry out the omnidirectional scanning to the building, need three to the spherical mark target more than three to carry out space location simultaneously, the accuracy of scanning spatial position has been decided to the precision of mark target, consequently, the erection of spherical mark target has played huge effect in the scanning.
Since spatial positioning is always the most critical step, the spherical target is erected by centering the prism rod, and then the scanner identifies the spatial position by the position of the spherical target. In three-dimensional laser scanning, the position of a spherical target frame station generally changes along with the actual situation, but the frame stations at different positions bring many accidental errors, the errors caused by the accidental errors are gradually increased due to the errors, a centering rod lacks certain stability in the process of erecting the existing ball target by the middle rod, and many accidental errors are generated due to the situation of an operator under the actual situation, so that the scanning result is influenced. In addition, in the actual measurement process, the situation that the height of the target ball cannot meet the requirement of the scanner easily occurs, and the device can greatly shorten the measurement time in the engineering through improvement.
Disclosure of Invention
In order to overcome the defects existing in the background technology, the utility model provides a telescopic positioning ball target fixing device.
The utility model provides a technical scheme of above-mentioned problem is:
a telescopic positioning ball target fixing device comprises a ground connecting device and a ball target placing device;
the ground connecting device comprises a reinforced concrete main body 1 and an underground foundation 5, wherein the underground foundation 5 is in an inverted T shape, the top of the underground foundation 5 is connected with the reinforced concrete main body 1, and the top of the reinforced concrete main body 1 is connected with the spherical target placement device;
the spherical target placement device consists of a carbon fiber rod 3 and a jacking screw 4, wherein the carbon fiber rod 3 comprises an upper section and a lower section, the lower section is sleeved outside the upper section, the jacking screw 4 is arranged in a screw hole on the wall surface of the lower section, the jacking screw 4 jacks the wall surface of the upper section, and the lower section is embedded in the reinforced concrete body 1;
the top of the upper section is provided with a slot buckle for mounting a target ball of the three-dimensional laser scanner;
The transverse portion of the underground foundation 5 has a length, width and height dimension of 120cm × 120cm × 80cm, and the reinforced concrete body 1 has a length, width and height dimension of 80cm × 40cm × 100 cm.
The beneficial effects of the utility model are that:
the utility model discloses simple structure, it is sturdy and durable, can realize the fixed observation of scanning ball target, it is more simple and convenient to operate, fixed effect is better, strong adaptability, application scope is wide. The stability is enhanced by arranging the foundation 5, and the carbon fiber rod 3 is buried in the concrete connecting column, so that the ball target is not easy to disturb; meanwhile, the adjusting knob 4 can be directly adjusted to a proper height according to the visual field of the scanner.
