Camera

Introduction

The VEX AIR Hornet includes two Vision Sensors that serve as its onboard cameras—one on the front and one on the bottom. These can capture both images and video during flight. In VEXcode AIR, the word “camera” always refers to one of these Vision Sensors. For instance, when forward and downward cameras are parameter options, they are referring to the forward facing Vision Sensor and the downward facing Vision Sensor.

Below is a list of available blocks:

Video

• show/hide camera video - Shows or hides camera feed on the controller.

Overlay

• overlay reticle - Shows or hides the overlay reticle.

• overlay vision objects - Shows or hides vision objects.

• overlay telemetry - Shows or hides telemetry data.

Capture

• start recording - Records a video from a Vision Sensor.

• stop recording - Stops recording a video from a Vision Sensor.

• capture image - Captures an image from a Vision Sensor.

• is camera recording? - Returns whether the Vision Sensor is recording.
