With the development of science and technology and information nowadays, sports are also developing in the direction of science and technology sports and green sports. At present, many sports include sports training and competitions. Mass fitness and school sports are evaluated by performance measurement, which puts forward higher requirements for the reliability and accuracy of sports performance measurement. Therefore, with the development of surveying and science and technology, the electronic laser measuring instrument is widely used in sports and various fields, which brings convenience to the measurement of sports performance. In this paper, the application of electronic laser measuring instrument in sports is studied by means of documentation, experimental comparison, mathematical statistics and field measurement.
