Automatic debugging system and method

Abstract

An automatic calibration system for a passenger transportation system includes a depth sensing sensor disposed within a passenger transportation enclosure or in a passenger waiting area external to the transportation enclosure for capturing depth map data of objects within a field of view. A processing module is in communication with the depth-sensing sensor to receive the depth map data, the processing module uses the depth map data to calibrate a sensor coordinate system to a global coordinate system.

Description

[0001] technical background [0002] The present disclosure relates to passenger transportation and, more particularly, to elevator installations. [0003] The installation of an elevator system incurs considerable expense and inconvenience in the labor, time, testing equipment, measuring devices and data entry required. This is exacerbated when using one or more 3D depth sensors for higher accuracy and additional functionality. [0004] The calibration of the 3D depth sensing system uses at least 6 positions at different measured (x,y,z) global coordinates. While 'finding' the position of the object can be used, for professional installations a portable calibration jig can be carefully placed in the measured global coordinates and the calibration data acquired by the 3D depth sensor. At least using global coordinates (x i ,y i ,z i ) and the coordinates observed by the corresponding 3D depth sensor (u i ,v i , d i ) data, the transformation matrix can be solved to achie...

Problems solved by technology

Other systems use multiple consecutive views of the same object to calculate the calibration parameters, but this may not be applicable since full calibration (including scale factors) is expected and most objects move in a non-uniform manner and deform during movement
