Automatic sensing scoring method and device for cornhole game, equipment and medium

An automatic sensing scoring method for a cornhole game, applied to a game board provided with a plurality of target holes, comprising the following steps:

• continuously transmitting infrared light beams at relative positions of each of target holes and receiving the infrared light beams in real time;
• recording a baseline level in an unshielded state;
• and updating a shielding judgment threshold regularly to compensate for ambient light changes and control a misjudgment rate within a preset reliability index;
• when it is detected that the infrared light beams are shielded, amplifying an electrical signal output by a receiving end through an operational amplifier, and suppressing high-frequency interference through a low-pass filter with a preset cutoff frequency while retaining envelope changes of a shielding event to obtain a scoring trigger signal;
• converting, by a microprocessor, the scoring trigger signal into a corresponding score according to a preset “hole-score” mapping table and adding the corresponding score to a cumulative score of a current contestant;
• and
• during a preset scoring period, outputting an updated cumulative score in real time through a digital display screen.
