flatness of the foundation floor, use frequencies, indoor and outdoor ambient air temperature and
humidity, light and the like; and the surface layer and overall structure of the professional sport
floor are prone to deformation, leading to the local fluctuation or stagger phenomenon of the
surface layer. Not only the properties of the sport field are affected, but also the severe safety
potential hazard may be caused for people exercising on it.
However, most of the existing professional sport floor surface detection instruments focus
on the detection of surface wear resistance, friction performance, elasticity, hardness and the like.
The detection device, detection method and quality determination for the surface flatness of the
sport floor are limited to macro and simple detection tools and methods for the limitation of
standard values and cannot measure the floor flatness in a specified area and a relative height

accompanying drawings and specific embodiments.
As shown in Fig. 1, the sport floor flatness detection device includes a main shaft 1, a tripod
2, a rotation driver 3 and a laser distance measuring instrument 4. The main shaft 1 is vertically

measurement position. The cross bar 21 stops rotating after rotating for 360°, and then the
surface flatness data of a circumference with the radius of R1 is obtained. The reflective
triangular laser distance measuring instrument is adjusted to the to-be-detected radius R2 to
repeat the above operation. Finally, according to the data acquired by the reflective triangular
laser distance measuring instrument, a measurement plane of the annular area with the radius of
RN-Ri is drawn, and a relative height difference of different points is determined. A specific
location of one point can also be determined according to the measurement start point, the
measurement time t X the rotation speed a and the measurement radius RN, thereby carrying
