Client Device Sensor Transmission for 3D Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand for effectively transmitting information for creating three-dimensional data, particularly in environments where mobile objects need to share sensor information to construct accurate three-dimensional maps.
Innovation Solution
An information transmission method in a client device of a mobile object, which involves obtaining sensor information, determining if the mobile object is in an environment capable of transmitting this information to a server, and then transmitting the sensor information when such conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor information is continuously transmitted to create three-dimensional data, then the accuracy and completeness of three-dimensional maps improve, but the communication bandwidth consumption and data transmission load increase
Solution Approach 1:
The patent extracts and transmits only the necessary sensor information for creating three-dimensional maps, rather than continuously transmitting all sensor data. The client device determines whether transmission is needed based on whether the mobile object is in an environment capable of receiving the information, thereby reducing overall data transmission while maintaining map accuracy.
2Loss of information
If sensor information is transmitted in all environments, then no data is lost, but unnecessary transmissions waste communication resources and energy
Solution Approach 1:
The patent implements dynamic transmission control where the client device adapts its transmission behavior based on environmental conditions. The device determines whether the current environment supports information reception before transmitting, making the transmission process flexible and context-aware rather than static and unconditional.
Solution Approach 2:
The client device autonomously determines whether transmission conditions are met without requiring external instructions. It self-manages the transmission decision-making process by evaluating environmental capabilities, thereby avoiding unnecessary transmissions and conserving energy while ensuring important data is transmitted when appropriate.
3Reliability
If the client device always transmits sensor information, then the server receives complete data for map creation, but the device complexity and processing load increase
Solution Approach 1:
The patent performs preliminary assessment of transmission conditions before actual data transmission. The client device evaluates whether the environment is capable of receiving information in advance, and only proceeds with transmission when conditions are favorable. This preliminary check simplifies the overall transmission control logic while maintaining reliability.

AI summary
An information transmission method in a client device provided in a mobile object includes: obtaining sensor information that has been obtained by a sensor provided in the mobile object and indicates a surrounding state of the mobile object, and storing the sensor information into a storage; determining whether the mobile object is present in an environment in which the mobile object is capable of transmitting the sensor information to a server; and transmitting the sensor information to the server when the mobile object is determined to be present in the environment in which the mobile object is capable of transmitting the sensor information to the server.
