A Cycle

All TrueView sensors and microdrones traditional sensors, write their various data streams to a standard file folder structure called a “Cycle” on the USB drive or internal memory. The term cycle refers to a sensor power cycle because TrueView datasets are started and terminated by the sensor power cycles. It is possible to have multiple collections (flights, in the case of a drone) in a single Cycle, so it is not necessarily correct to think of Cycle as being synonymous with flight, though it is typically.

Apart from the TV540 and TVGO (documented below), the folder structure requires four basic components to be a valid Cycle for import into LP360 Drone:

• The folder name must have “Cycle_” at the beginning of the name.
• There must be a sub-folder in the Cycle folder named “System”.
• In the System folder there must be a “SystemConfiguration.json” file.
• In the System folder there must be a “CycleParams.json” file.

If the user changes the file structure in a way where these conditions are not met, the cycle will not be valid for import.

|        CycleParams.json

Example of proper file structure

For the TrueView 540 by CHCNAV LiDAR payload, there is no USB, so the Cycle data must be copied from the payload to your local drive using the TV540 Data Copy tool found in the Utilities group on the Sensor tab of the ribbon. Please reference the TV540 Hardware users guide for more information regarding data storage and verifying the validity of collected data.
