昼光の堅牢性#

This topic describes how the daylight robustness of the Basler blaze-101 camera has been tested.

The daylight robustness was tested under the following conditions:

  • Flat, white target with 90 % reflectivity
  • Target illuminated by 940 nm LED
  • 6 m distance between target and camera
  • Exposure time of 250 µs

Test Setup#

The camera was pointed directly at a flat, white target at a distance of 6 m. To simulate ambient light, the target was illuminated by an additional light source using the same wavelength as the camera. The irradiance on the target was increased up to the point where the camera still delivered usable images without overexposure. The irradiance was measured and the increase in noise was determined based on the camera images.

Daylight Robustness Test Setup

Test Results#

The camera still delivered usable images at an ambient irradiance of 12.8 W/m² for ambient light sources between 920–970 nm. The image noise increased by a factor of 7.
