Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by pre-calculating the planar mapping relationship between the display plane and imaging plane before actual image capture. This allows the display content to be pre-deformed according to the calculated mapping, so that when captured by the imaging device, the deformation is compensated and minimal alignment adjustments are needed.

Inventive Principle:

Solution Approach 2:

The system changes display parameters by dynamically adjusting the display content's shape and position parameters based on the planar mapping relationship. This parameter transformation allows the display content to be rendered in a pre-deformed state that compensates for expected imaging deformation, reducing the need for precise alignment operations.

Solution Approach 1:

The system applies preliminary anti-action by pre-deforming the display content in the opposite direction of expected imaging deformation. The planar mapping relationship calculation determines the compensation transformation needed, and the display content is rendered with this counter-deformation applied, so that when captured, the deformations cancel out and high-quality undistorted images are obtained.

Solution Approach 1:

The system replaces manual mechanical alignment operations with automated computational methods. Instead of requiring physical adjustment of imaging device posture and alignment, the system uses planar mapping relationship calculation and software-based deformation compensation to achieve the same goal of minimizing image deformation, thereby improving image processing correctness while managing complexity through automation.

AI summary

Various display control methods and apparatuses are provided. A method comprises acquiring planar mapping relationship information between an imaging plane and a display plane, and deform-displaying the display content on the display plane at least according to the planar mapping relationship information, to reduce a deformation degree of an image formed by the deformed display content on the imaging plane. A requirement for alignment precision of an imaging device required by the imaging plane is reduced to acquire an image of the display content deformed less to some extent, and users' operational convenience is increased.
