Description
Technical field
The invention belongs to laser ranging field, more particularly to a kind of laser ranging system.
Background technology
Laser range finder is the instrument for carrying out Accurate Determining to the distance of target using laser, according to the work side of laser
Formula, can be divided into continuous wave laser and pulse laser.Operationally, a branch of very thin laser is projected to target, by photo elements
Part receives the laser beam of target reflection, and timer determines laser beam from the time for being transmitted into reception, calculates observation station to target
Distance.
Hand-held laser rangefinder popular at present is because price is relatively cheap and is widely applied, and it is measured
When laser range finder must be aligned to one end of object to be measured to determine the length of object to be measured.Such as to measure a face wall
Length, one end of laser range finder must be adjacent to one end of metope to be measured.In another example, it is necessary to certain two point distance in space
When measuring, the size of an object on such as ceiling, because its one end for needing to be fixed on object to be measured, causes measurement to be difficult to
Realize.
Existing another laser ranging instrument be laser total station, its can realize between any two points of space away from
From measuring, it has an optical path, and the coordinate of a point is first measured and recorded when measurement, then measures another again
The coordinate of an outer point, then calculates the distance between two points again, must install fix in the measurements, whole measurement process
There can not be any movement, and to take multiple measurements.
Therefore, in summary, limitation of the existing laser ranging system due to equipment in itself, causes operation relatively complicated,
Great inconvenience is brought to measurement work, and needs miscellaneous part to be fixed in measurement process, equipment cost is not only increased,
Also result in overall portability bad.
The content of the invention
The embodiment of the present invention provides a kind of laser ranging system, it is intended to solve existing laser ranging system it is cumbersome,
Cost is higher, and overall portability it is bad the problem of.
The embodiment of the present invention is achieved in that a kind of laser ranging system, including：
First laser range cells, the range information for measuring first object point；
Second laser range cells, the range information for measuring the second target point；
Angle detection unit, for detecting between the first laser range cells and the second laser range cells
Angle information；
Processing unit, available for range information, the range information of the second target point, the angle letter to the first object point
Breath carries out calculating processing, to obtain the distance between the first object point and the second target point；And
Man-machine interaction unit, for being shown to the distance between the first object point and the second target point, Yi Jizhi
Hold the setting and control of user.
The laser ranging system that the present invention is provided, passes through first laser range cells and second laser range cells same time-division
Other measurement space first object point and the second target point range information, and first and second Laser Measuring is measured by angle detection unit
Away from the angle information between unit, most calculate the distance between first object point and second target point through processing unit afterwards and lead to
Man-machine interaction unit is crossed to be shown measurement result because be provided with simultaneously two laser ranging units and two range cells it
Between relative position can freely adjust, may be implemented in cost it is controllable on the basis of essence easily is carried out to the distances of space any two points
Really measurement, solves existing laser range finder cumbersome, instrument when the distance to space any two points is measured whole
Body portability is bad and the problem of higher cost.
