Abstract
The invention provides a camera base. The camera base comprises a base body and a grating scale arranged on the base body, wherein the grating scale comprises a scale grating and a grating reading head; the base body comprises an upper turntable and a lower fixed base; the scale grating is annularly arranged at the joint of the turntable and the fixed base; the fixed base is connected with the scale grating; the turntable is connected with the grating reading head. The camera base has the beneficial effects that the movement displacement of the base in an annular range can be obtained by arranging the annular scale grating and cooperating with the grating reading head; the rotational angle of the base can be calculated via the annular movement displacement obtained by the grating scale, and the initial position of the base can be easily obtained by combining the rotational angle with the current angle of the base.
Description
Technical field
The present invention relates to base field, especially a kind of camera base.
Background technology
Camera base plays very important effect in the shooting process of video camera, play stable video camera, prevent float and the effect of long-time stable shooting, but fixing seat currently on the market is typically all and plays simple fixing supporting role, can realizing in the certain limit of video camera mobile, when shooting for a long time, photographer often forgets the moving process of video camera, it is difficult to find initial shooting point, causes very big puzzlement for later record or picture comparison.
Summary of the invention
This use Novel main to solve the technical problem that and to be in that to provide a kind of camera base.
The present invention solves that the technical scheme that above-mentioned technical problem adopts is:
A kind of camera base, the grating scale including base and be arranged on base, described grating scale includes scale grating and grating reading head, and described base includes the turntable being arranged at top and is arranged at the fixing seat of bottom, and the junction of described turntable and fixing seat is equipped with grating scale；
Described grating scale includes scale grating and grating reading head, and described scale grating is arranged at fixing seat top, and described grating reading head is arranged at turntable bottom；
Described fixing seat bottom portion is provided with spider, and described spider is connected by telescopic arm with fixing seat.Described grating scale is connected to independent current source.Described telescopic arm includes expansion link and multi-directional ball, and described multi-directional ball is arranged at expansion link one end.Described expansion link is electric expansion bar.Described multi-directional ball is plastic-steel ball.
Further, described turntable is electric rotary table.
Further, described independent current source is lithium battery.
Beneficial effects of the present invention:
1. by the setting of ring gauges grating, coordinate grating reading head, just can draw base moving displacement in an annular extent, by the annular movement displacement that grating scale obtains, just can extrapolate the rotational angle of base, in conjunction with the angle residing for current base, it is possible to draw the initial position of base very easily.
2. the displacement measurement of grating scale is very accurate, and then the move angle extrapolated by the displacement data of grating scale is also very accurately, and efficiency is very high, and grating scale has substantially no effect on the original service efficiency of base and convenience.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of detailed description of the invention of the present invention.
Fig. 2 is the top view of a kind of detailed description of the invention of the present invention.
In figure: 1 is turntable, 2 is fixing seat, and 3 is scale grating, and 4 is grating reading head, and 5 is telescopic arm, and 6 is spider.
Detailed description of the invention
Please refer to Fig. 1 and Fig. 2, for a kind of detailed description of the invention of the present invention.
A kind of camera base, the grating scale including base and be arranged on base, described grating scale includes scale grating and grating reading head, and described base includes the junction of the turntable 1 being arranged at top and the fixing seat 2 being arranged at bottom, described turntable and fixing seat and is equipped with grating scale；Described grating scale includes scale grating 3 and grating reading head 4, and described scale grating is arranged at fixing seat top, and described grating reading head is arranged at turntable bottom；
Described fixing seat bottom portion is provided with spider 6, and described spider is connected by telescopic arm 5 with fixing seat.
Grating scale is connected to independent current source.
Telescopic arm includes expansion link and multi-directional ball, and described multi-directional ball is arranged at expansion link one end.Expansion link is electric expansion bar.Multi-directional ball is plastic-steel ball.Turntable is electric rotary table.Independent current source is lithium battery.Spider material is high strength plastics.
Setting by ring gauges grating, coordinate grating reading head, just can draw base moving displacement in an annular extent, by the annular movement displacement that grating scale obtains, just can extrapolate the rotational angle of base, in conjunction with the angle residing for current base, it is possible to draw the initial position of base very easily.
The displacement measurement of grating scale is very accurate, and then the move angle extrapolated by the displacement data of grating scale is also very accurately, and efficiency is very high, and grating scale has substantially no effect on the original service efficiency of base and convenience.
