Embodiment 1
[0054] Please refer to figure 1 , the present application discloses an illumination detection system, which includes a light source assembly 11, an imaging device 12, a control device 13 and a processing device 14, which will be described separately below.
[0055] The light source assembly 11 is used to perform pattern illumination on the object W1 to be detected in the illumination area, and needs to project the structured light required for pattern illumination to the object W1 to be detected multiple times. In a specific example, see figure 2 , the light source assembly includes at least one lighting module (such as the module shown by reference numeral 112), and each lighting module 112 is used to project structured light to the object W1 to be detected in the same direction or in different directions. It can be understood that the structured light here refers to the light projection state indicating that the dark light signal is distributed according to a certain rule....
Embodiment 2
[0069] Please refer to Figure 4 , on the basis of the lighting detection system disclosed in Embodiment 1, some structural improvements can also be made to the lighting detection system, for example, the control device 13 and the processing device 14 are integrated in a device main body Z1, specifically, they can be integrated in a circuit On the board, the same processing chip or different processing chips realize the functions of trigger drive control, object imaging control, and image processing, which can reduce hardware overhead, and the user can simultaneously realize detection control and image processing with the main body Z1 of the device Function.
[0070] see Figure 4 , the device main body Z1 is also provided with a detection configuration module 15 signal-connected to the control device 13, the detection configuration module 15 is used to configure the operating parameters of the light source assembly 11 and imaging device 12, so that the control device 13 acco...
Embodiment 3
[0077] Please refer to Figure 7 , On the basis of the illumination detection device disclosed in Embodiment 1 or Embodiment 2, this embodiment discloses a three-dimensional measurement method based on structured illumination, the three-dimensional measurement method includes steps S100-S300, which will be described respectively below.
[0078] Step S100 , acquiring multiple projection images of the object to be detected under the irradiation of multiple projections of structured light. such as in figure 1 with figure 2 Among them, the control device 13 can not only control one of the lighting modules 112 to project the structured light from the same direction multiple times, but also control a group of two lighting modules 112 arranged diagonally to project the structured light alternately from different directions, or control Multiple groups of lighting modules 112 arranged diagonally project structured light alternately from different directions, and it is even possible ...
