Problems solved by technology

Although this solution solves the defects of traditional adhesive plaster markings, etc., it needs to use an infrared low-light camera to feed back the specific position effect, the camera is expensive, and most of the existing cameras have no night vision function, even if there is a night vision Vision function, the camera has a large error in shooting in the dark, which will still affect the positioning
In addition, after the infrared low-light camera captures the laser projection effect on the stage, image analysis is required, and the processing process is complicated

Abstract

The invention relates to the field of positioning, and particularly relates to a stage laser positioning calibration device and a stage laser positioning calibration method. The device comprises a master control manipulator, a display and a laser scanning transmitter installed above a stage, wherein the master control manipulator is connected with the display and the laser scanning transmitter respectively. The device also comprises a positioner arranged on a positioning object and a positioning data receiver in wireless connection with the positioner, wherein the positioning data receiver is connected with the master control manipulator. According to the stage laser positioning calibration device and the stage laser positioning calibration method provided by the invention, the defect that a laser projection effect is affected by stage light when a camera is adopted for shooting the stage can be overcome, the high cost of the camera is saved and an image analysis step which is needed after the camera is used for shooting images is omitted, and the entire calibration device is simple in structure, convenient for calibration operation, high in positioning and calibration speeds, and low in cost.

Description

technical field [0001] The present invention relates to the field of positioning, and more particularly, to a stage laser positioning calibration device and method. Background technique [0002] At present, the known stage positioning marks are carried out by means of adhesive plaster, post-it notes, pasting with colored pens, sketching, etc. Most of the cameras on the stage do not have night vision functions, and even if they have night vision functions, the positioning is not accurate. It is difficult for actors and dancers to accurately find the predetermined position under the state of black light on the stage. They can only find the positioning marks with the help of low light. In addition, during multi-scene performances, each scene mark overlaps with each other, making it more difficult to accurately find the predetermined position. Especially on the stage of the TV studio theater, the messy positioning marks also cause direct pollution to the TV screen, seriously af...
