specific Embodiment 1

[0025] This embodiment is an embodiment of a field monitoring and management device for ice and snow sports.

[0026] The site monitoring and management device for ice and snow sports in this embodiment, such as figure 1 and figure 2 shown. The site monitoring and management device includes two rows of brackets 1 symmetrically arranged at both ends of the site, a slideway 2 arranged on the top of each row of brackets 1, and a sliding end 3 spanning the two slideways 2. The sliding end 3 includes mutual Parallel, first crossbar 31, the second crossbar 32 and the third crossbar 33 that spacing is fixed; The first crossbar 31 is equipped with a plurality of cameras 4, and the second crossbar 32 is equipped with the same number of cameras 4 Probe 5, the blower 6 that one more than probe 5 quantity is installed on the 3rd crossbar 33; The connection line of described camera 4 and corresponding probe 5 is parallel to slideway 2, and described probe 5 is positioned at adjacent two...

specific Embodiment 2

[0027] This embodiment is an embodiment of a field monitoring and management device for ice and snow sports.

[0028] The venue monitoring and management device for ice and snow sports in this embodiment, on the basis of specific implementation, further defines that the two ends of the probe 5 are connected to the spring 7, and the outer end of the spring 7 is connected to the handle end 8. , the handle end 8 is L-shaped, one end is connected to the spring 7, and the other end is connected to the second cross bar 32, and the probe 5 is rotated around the position of the spring 7 under the action of the spring 7, as image 3 shown.

specific Embodiment 3

[0029] This embodiment is an embodiment of a field monitoring and management method for ice and snow sports.

[0030] The field monitoring and management method for ice and snow sports in this embodiment is implemented on the field monitoring device for ice and snow sports described in the first or second embodiment. The method includes the following steps:

[0031] Step a, setting segmentation threshold A and detection threshold B;

[0032] Step b. According to the segmentation threshold A, the image formed by the camera 4 is subjected to threshold segmentation processing, and the processing method is as follows:

[0033]

[0034] Step c, start searching from the last line, find the first point where f(i,j)=0, and record the ordinate C of the point;

[0035] Step d, compare the size of the ordinate C and the detection threshold B, if:

[0036]

[0037] Step e, recording the position y of the second crossbar 32 relative to the slideway 2 and the position x of the prob...

Abstract

The invention provides a device and a method for monitoring and managing a site of ice-snow sports, and belongs to the technical field of monitoring and management of ice-snow sports. The device comprises two rows of support frames which are symmetrically arranged at two ends of the site, sliding rails arranged at the top of each row of support frame, a sliding end stretching across two sliding rails, and a camera, a probe and an air blower which are mounted on the sliding end. The method comprises the following steps: firstly setting a segmentation threshold and a detection threshold, then carrying out threshold segmentation processing on an image formed by the camera, then finding a first point with a pixel gray value of 0 from the image, recording a vertical coordinate of the first point, comparing the vertical coordinate with the detection threshold, and finally concluding whether the first point is dangerous. The device and the method for monitoring and managing the site of ice-snow sports can be used for recognizing sundries such as hidden stones and the like in the site, ensuring the safety of the site of ice-snow sports favorably, and accelerating the development of ice-snow sports.

Description

technical field [0001] The invention relates to a field monitoring and management device and method for ice and snow sports, belonging to the technical field of ice and snow sports monitoring and management. Background technique [0002] As an important outdoor sport in the north in winter, ice and snow sports have always been loved by the masses. As Beijing and Zhangjiakou won the right to host the 2022 Winter Olympics, my country's ice and snow sports have also ushered in a major opportunity for development. At present, 29 provinces across the country have launched ice and snow sports, which has consolidated the ice and snow sports pattern based on the Northeast, focusing on Beijing and Hebei, and gradually developing in western and southern parts of the country. With the preparation of the Winter Olympics, the upsurge of ice and snow sports will be further set off across the country. [0003] Unlike summer sports, ice and snow sports are more dangerous. On December 29,...
