Technical solution of the present utility model is as follows:
A kind of device of Measuring Object size, be characterized in comprising camera, a base that is used to place this camera, the left and right sides is respectively equipped with laser bench on this base, respectively is provided with the laser head of a pair of vertical direction on the position of the homonymy equal height of these two laser bench.LASER Light Source is arranged in order to launch laser beam in the laser head.The laser beam that the laser head of the left and right sides is launched is a transverse beam, is used to measure length, and the laser beam launched of two laser heads is vertical bundle up and down, is used for measuring height, and the distance between the practical laser head is a fixed value.
The left and right sides is respectively equipped with many rows adjustable port parallel to each other on the described base, and the corresponding position of the adjustable port on described laser bench bottom and described base is provided with through hole, makes suitably left and right adjusting of two distances between the laser bench.
Described base middle part is provided with two-way screw, this two-way screw be connected with fixing head to top, camera is fixed on the base reposefully, be convenient to better fixed angle and take pictures, two-way screw to the lower part base and spider are fixed.The mid portion of two-way screw is used for regulating in the same way the degree of tightness of two head screws for the screw dish.
The measuring method of the device of described Measuring Object size comprises the steps:
1. described camera is fixedly mounted on the described base, and measures distance and the distance between two laser heads up and down between the laser head of the described left and right sides;
2. open switch, allow described laser head launch laser beam, make laser beam irradiation back reflection on object under test;
3. this object under test is taken a picture;
4. measure in the photo laterally in the distance between the laser point and photo the vertically distance between the laser point;
5. calculate the length and the height of object under test:
, wherein:
Be the length or the height of object under test,
Be the length or the height of object under test in the photo,
Be distance between the laser head of the left and right sides or the distance between two laser heads up and down,
Be the distance between vertical laser point in distance between the horizontal laser point or the photo in the photo.
Design principle of the present utility model is the ratio that the ratio of the distance of laser point on distance and the photo that utilizes between the practical laser bundle is extrapolated object in kind and the photo, thereby calculates the physical length and the height value of object under test.
Compared with prior art, technique effect of the present utility model is by utilizing laser the outer animal of certain distance to be locked and stays the characteristics of the laser point marking on photo, calculate the length of actual animal, highly, and then extrapolate animal local area volume, play and neither alarm animal, do not influence the effect of measurement result yet, convenient and swift, improved work efficiency.
