Title:
RECOGNITION AND POSITIONING DEVICE AND INFORMATION CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/235286
Kind Code:
A1
Abstract:
The present invention simultaneously recognizes in-image objects from a moving image and acquires three-dimensional coordinates for the objects. The present invention comprises a CV video acquisition unit 20 that generates CV video by adding a CV value to target video, an object designation unit 13 that designates objects to be recognized that appear across a plurality of frames of the CV video, a consecutive frame machine learning unit 30 that repeatedly performs machine-learning-based recognition processing on the designated objects, a three-dimensional coordinate computation and object coordinate addition unit 40 that associates recognized objects across all of the frames of the CV video, identifies the objects in each frame that match the coordinates of each appearing object, and adds three-dimensional position coordinates to the objects, and a coordinate addition and recognition output unit 41 that, by repeating object recognition and three-dimensional position coordinate addition between the consecutive frame machine learning unit 30 and the three-dimensional coordinate computation and object coordinate addition unit 40, adds three-dimensional coordinates to objects for which a prescribed recognition accuracy and three-dimensional coordinate precision have been obtained and outputs the objects.
