Abstract

The invention relates to a pulse laser-based positioning device and method, which belongs to the technical field of photoelectric tracking. The positioning device comprises: a Laser beacon source, a pulse detector, a photodetector, an image preprocessing unit, a data processing unit and a display. At least three laser beacon light sources are fixedly mounted on the object to be tracked, and simultaneously emit a laser pulse signal and a radio pulse signal. The pulse detector is used to receive the radio pulse signal and adjust the exposure time of the photodetector. The Photodetector is used to capture laser pulse signals and convert them into images. The image preprocessing unit is configured to convert the image into a data signal. The data processing unit calculates the position of thelaser beacon light source according to the data signal of the image, and finally converts to the position of the object to be tracked. The display is used to display images and position information ofthe object being tracked.

Description

technical field [0001] The invention relates to the technical field of photoelectric tracking, in particular to a pulse laser-based positioning device and method. Background technique [0002] In general, the photoelectric tracking system improves the tracking performance of the system and the adaptability in complex environments by installing cooperative beacons on the tracked object. It can usually be applied to ships or oil drilling platforms when offshore helicopters take off and land relative to ships or oil drilling platforms. The drilling platform detects the position and attitude of the aircraft relative to the take-off and landing deck, or the garage detects the position and attitude of the car relative to the garage when the car is parked in place. However, the photoelectric tracking system is easily affected by factors such as large background signal noise and limited cooperative beacon power. The signal-to-noise ratio of the system is not high, and the recognitio...
