Abstract: A bracket includes a bracket body and an imaging module. The imaging module includes a first light source, a first pattern plate, a second light source, a second pattern plate and an imaging screen. The first light source projects a first illumination light. The first pattern plate having a first transmissive pattern is located on an optical path of the first illumination light, such that the first illumination light passing through the first transmissive pattern becomes a first pattern light. The second light source projects a second illumination light. The second pattern plate having a second transmissive pattern is located on an optical path of the second illumination light, such that the second illumination light passing through the second transmissive pattern becomes a second pattern light. The imaging screen receives the projection of the first and second pattern light.
