Embodiment Construction

[0045] (1) Remove the bottom and two sides of the outer frame, install the white average ceramic plate on the space adjuster, and install the bottom and two sides of the outer frame.

[0046] (2) Power on the device to preheat the components.

[0047] (3) Drive the controller to output the initial voltage and current, turn on the measurement radiation source, and wait for the measurement radiation source to emit radiation stably.

[0048] (4) The space adjuster drives the measured white average ceramic plate to deviate from the initial position.

[0049] (5) The spectral sensor starts to measure and record the stray light in the outer frame.

[0050] (6) The spectral sensor is driven by the two-way locator to move towards the storage cabinet, and the photosensitive surface of the spectral sensor is aligned with the measurement radiation source. The center of the photosensitive surface of the spectral sensor and the center of the measurement radiation source are on the same ho...

Abstract

The invention discloses a device and method for bearing a retroreflection quantity value by a Lambert body, and belongs to the field of traffic safety. The device comprises a measurement radiation source, a spectrum sensor, a space adjuster, a bidirectional positioner and a two-dimensional aligner. The spectrum sensor is used for collecting and measuring spectrum data of the radiation source and spectrum data of reflected light of the Lambert body, and respectively calculating and regulating related color temperature and a retroreflection quantity value curve of the measured Lambert body under different pose and angle combinations. According to the invention, the retroreflection quantity value borne by the Lambert body is obtained by measuring the change of the spectrum data of the radiation source and the spectrum data after the radiation source is reflected by the Lambert body. According to the invention, the correlated color temperature of the measured radiation source is automatically adjusted, so that the accuracy of each measurement result is ensured. The Lambert body is used for bearing the retroreflection quantity value, so that the retroreflection quantity value can be stored for a long time through the stable Lambert body.
