Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging control systems fail to efficiently and accurately acquire divided images with secured margins, which is crucial for generating high-quality composite images, especially in applications like damage detection on concrete surfaces, where a whole image may not fit in one frame, leading to potential omissions during image composition.
Innovation Solution
An imaging control device and method that includes a wide-angle image acquisition unit, imaging information acquisition unit, margin information acquisition unit, region information acquisition unit, and a control unit to calculate and secure imaging regions for each divided image, ensuring proper overlap and efficient acquisition of close-up images, utilizing a moving camera object to capture images with calculated regions and adjust margin information based on resolution and feature points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If close-up imaging is performed to acquire high-definition captured images for damage detection, then image quality is improved, but the imaging target cannot fit in one captured image and multiple images must be composed
Solution Approach 1:
The imaging target is divided into multiple regions, and the imaging process is segmented into multiple close-up shots. The imaging control device calculates imaging regions for multiple divided images and controls the moving object to capture each region separately, ensuring high definition while covering the entire target area through composition of multiple images.
2Productivity
If divided images are acquired without considering margin, then imaging efficiency is improved, but the composite image may not be generated due to omission of imaging
Solution Approach 1:
The imaging control device performs preliminary calculation of imaging regions that include margin information before actual image acquisition. By pre-calculating the imaging regions with appropriate margins and controlling the moving object to capture these regions, the system ensures reliable composite image generation while maintaining imaging efficiency.
3Reliability
If margin is secured in divided images for composite image generation, then image composition reliability is improved, but imaging time and complexity increase
Solution Approach 1:
The imaging control device calculates imaging regions with margin information in advance, before the actual imaging process. This preliminary calculation of regions including margins allows for reliable image composition without adding significant time during the actual capture phase, as the margin considerations are resolved beforehand.
4Area of stationary object
If multiple divided images are acquired and composed, then complete coverage of the imaging target is achieved, but the complexity of image acquisition and composition increases
Solution Approach 1:
The imaging control device dynamically calculates imaging regions based on the wide-angle image and margin information, and dynamically controls the moving object's position and imaging parameters. This dynamic approach automates the complex process of acquiring multiple divided images with proper margins and composition, reducing operational complexity while achieving complete coverage.

AI summary
An imaging control device includes a wide-angle image acquisition unit 401, an imaging information acquisition unit 405, a margin information acquisition unit 407, a region information acquisition unit 409, an imaging region calculation unit 413 that calculates an imaging region of each of divided images constituting a composite image as each imaging region in a wide-angle image, in which a margin is secured, based on imaging information, margin information, and imaging target region information, and a control unit 411 that moves a moving object, makes the moving object image each calculated imaging region in a closed-up imaging mode with a camera, and acquires captured closed-up images as the divided images. The control unit 411 compares an image corresponding to each imaging region of the acquired wide-angle image with an image acquired in the closed-up imaging mode with the camera and controls a position of the moving object where the camera is made to image each imaging region in the closed-up imaging mode.
