Title:
PRECISION MEASUREMENT METHOD FOR BODY SENSE CAMERA AND PRECISION MEASUREMENT DEVICE OF BODY SENSE CAMERA
Document Type and Number:
WIPO Patent Application WO/2019/137347
Kind Code:
A1
Abstract:
Disclosed by the present invention are a precision measurement method and measurement device for a body sense camera. The method comprises: providing an LED light-emitting unit, which is a preset distance from a body sense camera; illuminating all LED light-emitting devices in the LED light-emitting unit; obtaining an infrared image of the LED light-emitting unit, and calculating a position and quantity of the LED light-emitting devices in the infrared image according to the infrared image, and comparing the quantity to the actual quantity of the LED light-emitting devices; when the two are consistent, obtaining a depth image of the LED light-emitting unit; locate depth positions of the LED light-emitting devices in the depth image according to the positions of the LED light-emitting devices in the infrared image in order to obtain a depth value of the LED light-emitting unit; comparing the depth value of the LED light-emitting unit to the preset distance, and when the two are consistent, outputting a precision measurement success signal. The precision measurement method of the present invention may implement fully automated testing and omit time consumed by human judgment and measurement errors caused by human judgment, while being low cost and simple to implement.
