12 results about "Optical illusion" patented technology

An optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation. According to that, there are three main classes: physical, physiological, and cognitive illusions, and in each class there are four kinds: Ambiguities, distortions, paradoxes, and fictions. A classical example for a physical distortion would be the apparent bending of a stick half immerged in water; an example for a physiological paradox is the motion aftereffect (where despite movement, position remains unchanged). An example for a physiological fiction is an afterimage. Three typical cognitive distortions are the Ponzo, Poggendorff, and Müller-Lyer illusion. Physical illusions are caused by the physical environment, e.g. by the optical properties of water. Physiological illusions arise in the eye or the visual pathway, e.g. from the effects of excessive stimulation of a specific receptor type. Cognitive visual illusions are the result of unconscious inferences and are perhaps those most widely known.

Construction Blocks for Forming a Breeze Block Wall Having Different Depths at Its Edges and Along Its Sides

Construction block designs for a breeze block wall are disclosed, in which the resulting wall creates a Trompe l'oeil (optical illusion) response where the wall appears differently depending on a viewing angle. This is achieved via blocks with unique three-dimensional shapes giving rise to a wall whose front surface is not perfectly planar. The blocks are preferably three-or four-sided, include an interior space, and can be opened (e.g., at their tops) or closed. The orientations of the blocks can be changed both vertically and / or horizontally on the wall. Despite their irregular shapes, the blocks in the resulting wall can be contiguous (i.e., with the blocks in contact, perhaps through intermediary materials) both vertically and horizontally, and with breeze holes formed in the wall and defined by the interior spaces in the blocks.

Visual illusion demonstration device based on graph-sky double circles

The invention discloses and relates to a visual illusion demonstration device based on a graph-ski double circle, and belongs to an optical science popularization education instrument. A visual illusion demonstration device based on Figure and Stronus double circles comprises an exhibition stand, a track device, a magnet disc, a planetary gear device and a control panel. An audience controls the servo motor to rotate forwards or backwards through the control panel, the sun wheel is driven to rotate forwards or backwards, then the planet wheels are driven to rotate forwards or backwards, and the upper planet wheels are meshed with the gears to move anticlockwise along the upper inner gears. As the magnet disc is fixedly connected with the upper planet wheel, based on the Figuus bicircle theory, the circular magnet adsorbs the metal ball to do linear reciprocating motion along the groove track; when all the metal balls independently reciprocate in the respective groove tracks, a small circle formed by all the metal balls can form a clockwise or rolling visual illusion effect on the track disc. The scientific and technological exhibition hall demonstration device well solves the problem and makes up for the situation that a scientific and technological exhibition hall is lack of the demonstration device.

Construction Blocks for Forming a Breeze Block Wall Having Parallel Edges Set Differently in a Rectangular Projection

Construction block designs for a breeze block wall are disclosed, in which the resulting wall creates a Trompe l'oeil (optical illusion) response where the wall appears differently depending on a viewing angle.

The blocks are preferably three- or four-sided, include an interior space, and can be opened (e.g., at their tops) or closed. The orientations of the blocks can be changed both vertically and / or horizontally on the wall.

A robot follow teaching anti-interference system and method for high-paint-mist environment

The application discloses a robot follow-up demonstration anti-interference system and method for a high-paint-mist environment, relates to the technical field of industrial automation control and robot demonstration, and comprises a multi-source heterogeneous data sensing module, a pneumatic-optical coupling frequency domain prediction module, a self-adaptive frequency domain decoupling control module and a robot execution module. The application synchronously collects spatial kinematics data sequences and spraying fluid mechanics process data sequences of a demonstration site in real time through the sensing module; the prediction module is used for forward calculation of an optical refraction distortion base frequency caused by a pneumatic vortex at the front end of a spray gun; then the decoupling control module is used for self-adaptive directional peeling of the spatial kinematics data in the frequency domain dimension in combination with the distortion base frequency, so as to generate a pure and clean reproduced track and hand over the track to the execution module to drive the robot to reproduce. The application accurately eliminates optical illusion noise caused by high paint mist, and meanwhile, retains the process micro-motion characteristics of an operator.

The invention discloses a text verification code generation method based on visual illusion. The method comprises the following steps: step 1, generating a bright stripe color, a dark stripe color and a character color based on a verification code image canvas, and establishing a brightness and chromatic aberration relationship between the two stripe colors and the character color; step 2, generating fluid noise with spatial coherence based on the verification code image canvas to form a stripe type mask; 3, drawing pseudo-stroke interference on the background, and combining the pseudo-stroke interference with the mask to form a same-color interference layer; 4, drawing to-be-recognized characters in sequence, applying structural damage to a character layer, including cutting, same-color shielding and trap display, and rendering the characters to a canvas; and step 5, applying pixel-level jitter and salt-and-pepper noise to the character-containing composite image in the step 4, completing post-processing and outputting a final text verification code image. According to the method, the readability and recognition stability of human users to character contents are kept while the automatic recognition accuracy based on the deep learning model is remarkably weakened.

System and method for establishing a forced perspective illusion

A control system for establishing a forced perspective illusion includes a controller configured to control movement of a first portion of an object to cause the first portion of the object to move at a first speed with respect to an observer. The first portion of the object is positioned a first distance from the observer to establish a first visual angle. The controller is also configured to control movement of a second portion of the object to cause the second portion of the object to move at a second speed with respect to the observer. The second portion of the object is positioned a second distance from the observer, greater than the first distance, to establish a second visual angle, and the second speed is equal to the first speed multiplied by a ratio of the second visual angle to the first visual angle.
