The invention discloses a gate passing detection device and method based on a laser ranging element group and a medium, and the method comprises the steps: 1, deploying a plurality of laser ranging elements at one side of a gate, and enabling the laser ranging elements to obtain a group of distance information of a certain plane in a gate passing channel; the method comprises the following steps of 1, acquiring distance information of an object in a gate channel, 2, establishing a gate channel object position calculation model for the distance information by adopting a BP neural network, and 3, training the BP neural network, and adjusting the neural network according to errors to obtain a BP neural network-based gate channel object position calculation model meeting use requirements. According to the invention, a plurality of pairs of infrared correlation sensors are replaced by the element group of the laser ranging elements, the cost of the gate is reduced, the use scene of the gate in a narrow environment
