Abstract

The invention provides a target detection method which is applied to a target detection system, wherein the target detection system comprises first equipment and second equipment, wherein the first equipment comprises a first signal receiving device and a first signal transmitting device, the second equipment comprises a second signal receiving device and a second signal transmitting device. The method comprises the following steps of: in a first time period, the first signal transmitting device transmits a first signal, the second signal receiving device is used for receiving the first signal, the first signal receiving device stops receiving the signal, and the second signal transmitting device stops transmitting the signal; in a second time period, the second signal transmitting device transmits a second signal, the first signal receiving device is used for receiving the second signal, the second signal receiving device stops receiving the signal, and the first signal transmitting device stops transmitting the signal; and according to a detection result in the first time period and a detection result in the second time period, whether a detection target passes is determined. According to the method provided by the invention, signal self-interference can be avoided.

Description

technical field [0001] The present application belongs to the technical field of target detection, and in particular relates to a target detection method, system and computer-readable storage medium. Background technique [0002] The infrared beam sensor includes a transmitter and a receiver. Usually, the infrared transmitter and the infrared receiver are fixed on both sides of the monitored road, aisle, entrance and exit, etc. When the infrared beam passing through the detection channel is blocked by passing pedestrians and vehicles , the receiving part detects the interruption of the infrared signal, and outputs a signal representing the occurrence of occlusion. [0003] However, since the infrared emitting tube and the infrared receiving tube of the same device are installed on the same physical structure, the infrared light signal emitted by the infrared emitting tube may be transmitted to the device where it is located due to scattering, reflection, diffraction, etc. O...
