Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image measurement processing devices struggle to derive accurate three-dimensional coordinates when a specifiable feature point is not present in the subject, and there is a need for immediate recognition of the irradiation position of directional light for efficient work processes.
Innovation Solution
An information processing device that acquires images from multiple positions and measures the distance using directional light, deriving irradiation position pixel coordinates and executing processes based on the position specifiable or unspecifiable state to ensure accurate imaging position distance derivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a specifiable feature point is present in the captured image, then three-dimensional coordinates can be derived using conventional methods, but the method fails when no specifiable feature point is present
Solution Approach 1:
The patent introduces an irradiation position mark as an intermediary element that is superimposed on the captured image to indicate the irradiation position of directional light. This mark serves as a mediator between the laser irradiation system and the image processing system, enabling coordinate derivation without requiring natural feature points on the subject. The mark provides a reference that bridges the gap between physical irradiation position and digital image coordinates.
Solution Approach 2:
The patent changes the approach from relying on geometric features of the subject to using irradiation position information as a new parameter. By deriving coordinates based on where the directional light irradiates rather than on feature point geometry, the system adapts to subjects without specifiable features. The irradiation position pixel coordinates become the new basis for three-dimensional coordinate calculation.
2Productivity
If conventional image measurement processing is used, then processing can be performed when feature points are present, but immediate recognition of irradiation position is not achieved
Solution Approach 1:
The patent performs preliminary action by superimposing the irradiation position mark on the captured image in real-time as the image is acquired. This allows the irradiation position to be immediately identified without subsequent manual intervention or complex processing. The mark is prepared and displayed concurrently with image capture, eliminating delays in position recognition.
Solution Approach 2:
The patent replaces manual or complex mechanical measurement methods with an automated optical and digital processing system. The irradiation position is automatically detected through image processing of the superimposed mark, substituting manual measurement procedures with automated computational methods that provide immediate results.
3Measurement precision
If multiple imaging positions are used to derive coordinates, then accuracy can be improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent makes the imaging device universal by enabling it to perform both image capture and irradiation position indication functions through a single integrated system. The same imaging device that captures the subject also displays the superimposed irradiation position mark, eliminating the need for separate measurement devices and reducing system complexity while maintaining multi-position imaging capability.

AI summary
A derivation unit derives irradiation position pixel coordinates for specifying the position of a pixel corresponding to an irradiation position of directional light on the real space with respect to a subject, on the basis of the corresponding distance acquired by an acquisition unit, with respect to each of a plurality of second captured images included in a moving image acquired by the acquisition unit, and an execution unit executes a predetermined process as a process to be executed in a position specifiable state with respect to each of the plurality of second captured images, in a case of a position specifiable state where the position of the pixel which is specified by the irradiation position pixel coordinates derived by the derivation unit is the position of a pixel which is specifiable at positions corresponding to each other in the respective first and second captured images.
