Mars 2020 rover undergoes ‘sight test’

The rover’s cameras were checked for resolution and geometric accuracy using target boards with dot grids

The National Aeronautics and Space Administration’s (NASA) Mars 2020 rover has had its vision checked after several cameras were installed on the vehicle.

Machine-vision calibration was performed using target boards with dot grids placed at a range of distances from one to 40 metres away.

The target boards were used to confirm that the cameras met the project’s requirements for resolution and geometric accuracy.

The cameras on the Mars rover will be used for a variety of tasks, from examining Martian rocks and soil to enhancing the driving capability of the vehicle and targeting the vehicle’s laser.

NASA will use the Mars 2020 mission to prepare for human exploration of the red planet.
