Accompanying drawing explanation
Fig. 1 is the structural drawing of the stadimeter that the embodiment of the present invention provides.
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
Set forth detail in the following description so that fully understand the present invention.But the present invention can be different from alternate manner described here to implement with multiple, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention.Therefore the present invention is not by the restriction of following public embodiment.
Fig. 1 is the structural drawing of the stadimeter that the embodiment of the present invention provides, and describes in detail below in conjunction with Fig. 1.
Current stadimeter usually by user hand-held use, due to human body self, stadimeter in use can be shaken.Due to the generation of shake, cause the laser launched to produce deviation, in like manner, the reflected light of reception also can produce deviation, therefore can cause the measuring error of stadimeter.
Described stadimeter 100 (also claiming laser range finder) comprising:
Control chip 1;
The gyroscope 2 be connected with described control chip 1;
The laser range sensor 3 be connected with described control chip 1, described laser range sensor 3 is connected with generating laser 4, and described laser range sensor 3 is also connected with laser pickoff 5;
Receive the lens set 6 of laser that described generating laser 4 sends and the laser that described laser pickoff 5 receives; Described laser pickoff 5 comprises the snowslide pipe 61 receiving the laser that described lens set 6 is launched.
In specific implementation process, the model of described control chip 1 is PIC32MX440F128HT-80I/PT.The model of described gyroscope 2 is MPU6050.The model of described snowslide pipe 61 is AD500-9TO52S.
Stadimeter 100 provided by the invention, add gyroscope 2 in the structure, effectively can slow down the shake of stadimeter 100, and the object of Laser emission effectively can be determined by gyroscope 2, thus reduce the launching deviation of laser and the reception deviation of reflected light, the measuring accuracy of stadimeter 100 is provided.
Described lens set 6 comprises object lens (not shown) and receives the prism group (not shown) of the laser that described object lens are launched.Described prism group comprises at least two prisms, and between described prism, gummed connects, and the cemented surface of described prism is coated with spectro-film.The plane of incidence of the laser of the described object lens transmitting of reception of described prism is coated with anti-reflection film.
