Photometric measurement is based on photodetectors, devices (of several types) that produce an electric signal when exposed to light. Simple applications of this technology include switching luminaires on and off based on ambient light conditions, and light meters, used to measure the total amount of light incident on a point. More complex forms of photometric measurement are used frequently within the lighting industr… WebAug 1, 2024 · Our method allows the robot to manipulate an object without knowing whether it is rigid or deformable. To validate our approach, we conduct numerical simulations and experiments with both deformable and rigid objects. Introduction Humans are capable of manipulating both rigid and deformable objects.

WebPhotometric Moments as visual features We propose a new type of visual features for visual servoing : photometric moments.
