Description

Technical Field

[0001] This utility model relates to head detection, and in particular to a C-shaped structure for head detection. Background Technology

[0002] Most devices for head detection use a single camera for planar scanning. However, the distances from various head organs to the camera vary considerably. Therefore, this acquisition method requires the head to be confined to a certain angle range during recognition. Furthermore, it cannot perform well in some applications, such as eyeglass fitting. A single camera can only recognize the straight-line distance between the two eyes, but cannot recognize the actual distance and curvature between the two eyes, nor can it recognize the actual distance between the ears and the eyes.

The support plate screw holes and support screw holes are in a vertical position, that is, the screws fix the support plate to the bracket through the two screw holes. The support plate is C-shaped, with a protruding edge at its bottom, that is, the cross-section of the support plate is L-shaped, and its support screw holes are located on the protruding edge.

[0027] To reduce material usage and weight, in some embodiments, preferably, the bracket includes a symmetrical upper bracket and a lower bracket, which are fixed by a plurality of fixing posts. Simultaneously, the bracket is perforated, i.e., it has a plurality of through holes, which can also serve as positioning holes. The support plate is positioned between the upper and lower brackets.

[0028] Preferably, the bracket is provided with positioning holes, and the housing is provided with corresponding positioning posts inside. This facilitates the quick installation of the housing. To further facilitate the installation of the housing, preferably, the housing includes an upper left housing, a lower left housing, an upper right housing, and a lower right housing. In order to reduce mold development and management costs and manufacturing costs, the upper left housing and the lower right housing are made of the same model, the lower left housing and the upper right housing are made of the same model, and the upper left housing and the lower left housing are symmetrically arranged.

[0029] Furthermore, to enhance overall sealing, preferably, the bottom edge of the upper left outer shell and the top edge of the lower left outer shell have corresponding matching structures, and the right edge of the upper left outer shell and the left edge of the upper right outer shell have corresponding matching structures. For example, matching structures for protrusions and grooves.

[0030] In some embodiments, preferably, the bracket is provided with a mounting portion.

[0031] In some embodiments, preferably, the upper left outer shell and the lower left outer shell have corresponding right-angled notches at their right ends, and the upper right outer shell and the lower right outer shell have corresponding right-angled notches at their left ends. Thus, the four right-angled notches form a rectangular notch for providing the mounting portion.

[0032] To enhance the rigidity of the outer casing, in some embodiments, preferably, the outer casing is provided with reinforcing strips. The reinforcing strips are disposed inside the outer casing.

[0033] The inner shell can also be perforated, that is, several through holes are set evenly.
