Camera and Vision System Troubleshooting

Camera System Overview

The BESTMOW T-100 has four cameras:

Front cameras (×2): A binocular pair used for 3D reconstruction. They generate point clouds from stereo imagery. The RGB images and point clouds are used for obstacle avoidance, boundary detection, and visual localization.
Side cameras (×2): Positioned rear-left and rear-right, providing approximately 270° total coverage.

Cleaning the Camera Lenses

Use an alcohol wipe to clean the camera lenses. The BESTMOW app will send a notification when camera cleaning is needed.

Conditions That Affect Camera Performance

Rain and fog
Darkness (the mower has no headlights — external lighting is required for night operation)
Dirt, grass clippings, or debris on the camera lenses
Direct sunlight or extreme glare

Camera Error / "Camera Abnormal"

This is a hardware error. It typically means the X5 board has stopped receiving signal via the MIPI interface. It could also indicate a hardware problem with the camera module itself.

Do not attempt to troubleshoot camera hardware errors. Collect the customer's serial number and escalate to a human support agent. A developer will need to remotely log into the mower to check the status of the camera module.

Front Camera vs. Side Camera — Escalation Decision

Not all camera errors require replacement:

Side camera errors (rear-left or rear-right): Often a software anomaly. Try restarting the mower first. If the error clears after restart, no replacement is needed — it was a temporary software issue.
Front binocular camera errors (error 137, 222): These are serious hardware failures. If restarting does not resolve the error, the mower requires replacement. Escalate immediately — do not continue troubleshooting.

The front cameras are critical for obstacle avoidance and navigation. The side cameras provide supplementary coverage. This is why front camera failures are more urgent.
