LED display parameter collection equipment based on the long-focus camera of the present utility model can also comprise platform; Frame fixation is on platform; First motor places the below of platform, and its rotating shaft is connected with platform.
Control system control camera to LED display one by one module take, camera is passed to control system with shot image data.After camera is whenever finished the shooting of a module, by control system view data is carried out real-time analysis and handle.Then, control system to first motor output control command, makes first motor rotation according to analysis processing result.The rotating shaft of first motor drives platform and rotates in the horizontal direction, and the camera that is embedded in the framework just can rotate in the horizontal direction, adjusts shooting area.When next module all entered the shooting area of camera, control system was to first motor output control command, and first motor shuts down, and makes the shooting area of first camera can accurately navigate to the designated module shooting area.This process circulates always, until the collection of finishing whole row's module display parameter.
LED display parameter collection equipment based on the long-focus camera of the present utility model adopts the method for control automatically to control first motor rotation, and the first driven by motor camera is rotated in the horizontal direction, adjusts shooting area.In this process, the shooting location is controlled first motor by control system fully and is finished, and has increased data acquisition efficiency when having reduced human intervention.The utility model work is convenient, fast, stable, reliable.
As further improvement of the utility model be: riser is fixed on the platform, and framework places the top of platform; Second motor is fixed in a side of riser, and the through hole that its rotating shaft is passed on the riser is connected with framework.
Two risers are individually fixed in the both sides of platform upper frame; Second motor is fixed in a side of one of them riser, and the through hole that its rotating shaft is passed on this riser is connected with a side of framework; The opposite side of framework flexibly connects by transverse axis and another riser.
The control command running that second motor can send according to control system, and its rotating shaft drives framework and rotates in pitch orientation, adjusts the luffing angle of camera automatically.Camera just can rotate in level and pitching both direction like this, thereby finishes the collection of the LED display display parameter that are made of the multiple lines and multiple rows module automatically.
As of the present utility model further the improvement be: camera is embedded in the inside casing, and inside casing places framework; The 3rd motor is fixedly mounted on the rear wall of framework, and the through hole that the framework rear wall is passed in its rotating shaft is connected with the rear wall of inside casing.
The 3rd motor can turn round according to the control command that control system is sent, and its rotating shaft drive inside casing rotation, for camera increases the 3rd rotation dimension, rotates under three degree of freedom thereby control camera more neatly, to realize better camera locating effect.
