PTZ Camera Path Generation Based on Detected Object Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video capturing techniques using PTZ cameras do not consider the presence of objects when switching image capturing areas, resulting in videos that are not suitable for viewing as they follow the shortest path between designated areas without considering object presence.
Innovation Solution
An information processing apparatus that detects objects in the video and generates a moving path for the image capturing area to include these objects, ensuring a more engaging and suitable video capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the image capturing area moves along the shortest path between designated areas, then the movement efficiency is improved, but the video quality becomes poor because objects are not properly tracked
Solution Approach 1:
The system detects objects in the current field of view and uses this feedback information to dynamically adjust the moving path. The object detection results are fed back to the path generation unit, which modifies the path to ensure objects remain within the field of view during camera movement, thus maintaining video quality while still achieving efficient transitions.
Solution Approach 2:
The moving path is not fixed but dynamically generated based on real-time object detection. The path generation unit creates adaptive paths that respond to the presence and position of objects, allowing the system to optimize both movement efficiency and video quality by adjusting the trajectory according to detected object locations.
2Device complexity
If the moving path is generated independently of object presence, then the path generation complexity is reduced, but the video becomes unsuitable for viewing as objects are not tracked
Solution Approach 1:
The system uses its own object detection capability to automatically generate appropriate moving paths without requiring external intervention or complex pre-programming. The path generation unit leverages the detection results from the detection unit to self-determine the optimal path, eliminating the need for separate complex path planning systems while ensuring objects are properly tracked.
3Reliability
If object detection is integrated into path generation, then video quality is improved by tracking objects, but the processing complexity increases
Solution Approach 1:
The object detection and path generation functions are merged into an integrated process. The detection unit and path generation unit work together as a unified system where detection results directly inform path decisions, eliminating the need for separate complex processing stages and reducing overall system complexity while maintaining high video quality.

AI summary
An information processing apparatus includes one or more memories storing instructions, and one or more processors that, upon executing the stored instructions, perform obtaining a video obtained by an image capturing apparatus that captures a predetermined area, setting a first area that is a portion of the predetermined area to be captured by the image capturing apparatus and a second area that is a portion of the predetermined area to be captured, and is different from the first area, detecting an object in an area different from the first area and the second area of the obtained video, and generating a moving path of an image capturing area that moves between the first area and the second area based on a position of the detected object.
