Automatic Photography Triggering via Dual-Module Distance Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal remote control methods for automatic photographing are not convenient or accurate, often resulting in incorrect timing, cumbersome Bluetooth pairing, or poor speech recognition, especially in varying distances or noisy environments.
Innovation Solution
A photographing method using two modules to measure the distance of a to-be-photographed object and calculate its variation over time, triggering automatic photography when the variation is within a preset value, ensuring accurate and user-friendly operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a time for triggering photographing is set by a user, then the terminal can be triggered to photograph images automatically, but the user cannot exactly estimate a desired time point resulting in incorrect timing
Solution Approach 1:
The patent replaces the mechanical/manual time-setting system with an optical detection system. Two photographing modules capture images at different moments, and the system automatically calculates distance variations through image processing, substituting user estimation with optical measurement and automated computation.
Solution Approach 2:
The patent introduces an intermediary measurement system between the user and the photographing trigger. Instead of directly setting time, the user initiates a distance measurement process that uses image acquisition modules to calculate object distance, and the photographing is triggered based on this intermediate measurement result.
2Ease of operation
If the terminal is controlled to photograph images by way of a Bluetooth wireless transmission manner, then remote control is achieved, but setting operations of Bluetooth pairing before Bluetooth communication is cumbersome
Solution Approach 1:
The patent extracts the complex Bluetooth pairing process from the control mechanism and replaces it with a direct optical detection approach. The photographing control is achieved through image acquisition and distance calculation, eliminating the need for wireless communication setup and pairing operations.
3Ease of operation
If the terminal is triggered to photograph images via particular speeches, then voice control is achieved, but if a shooting distance is too long or the environment is noisy, the recognition rate may be very bad
Solution Approach 1:
The patent replaces the acoustic voice recognition system with an optical detection system. Instead of processing sound waves and speech patterns, the system uses photographing modules to capture images and calculate distance, substituting acoustic processing with optical measurement for more reliable operation triggering.

AI summary
The present disclosure relates to a photographing method, an apparatus, and a terminal. The method includes: using two photographing modules to acquire images of a to-be-photographed object at a first moment and a second moment after a preset time interval, and determining a distance of the to-be-photographed object according to image points formed by a point of the to-be-photographed object on photosensitive devices of the two photographing modules, and parameters of the two photographing modules; calculating a variation between the distances of the to-be-photographed object at the first moment and the second moment; determining whether the variation is less than or equal to a preset value; and photographing the to-be-photographed object if yes. By means of the above technical solution of the present disclosure, automatic photographing is realized, the operation is simple, user requirements can be satisfied, and user experience can be improved.
