Visual perception system and method for a humanoid robot
First Claim
1. A robotic system comprising:
- a humanoid robot having a plurality of robotic joints each being moveable using at least one actuator; and
a distributed controller configured to control the movement of each of the robotic joints, wherein the controller includes a visual perception module (VPM) that is configured to visually identify and track an object in the field of view of the robot under predetermined threshold ambient lighting conditions;
wherein the VPM includes;
a plurality of optical devices each configured to collect an image of the object;
at least one of a laser device and a range imaging device configured to detect positional information of the object; and
a host machine configured to;
process the image and the positional information to thereby visually identify and track the object;
automatically adapt an exposure time of the optical devices to prevent feature data loss of the image under the threshold lighting conditions; and
discriminate either of a black-on-black or a white-on-white feature of interest on the object by;
automatically evaluating a small area of interest in the image;
using a histogram to determine the extent of the range of illumination of the area of interest; and
processing the range of illumination to thereby identify the features of interest.

Abstract
A robotic system includes a humanoid robot with robotic joints each moveable using an actuator(s), and a distributed controller for controlling the movement of each of the robotic joints. The controller includes a visual perception module (VPM) for visually identifying and tracking an object in the field of view of the robot under threshold lighting conditions. The VPM includes optical devices for collecting an image of the object, a positional extraction device, and a host machine having an algorithm for processing the image and positional information. The algorithm visually identifies and tracks the object, and automatically adapts an exposure time of the optical devices to prevent feature data loss of the image under the threshold lighting conditions. A method of identifying and tracking the object includes collecting the image, extracting positional information of the object, and automatically adapting the exposure time to thereby prevent feature data loss of the image.
