Description of the Related Art Recently, as a method of selecting and inspecting bulky fruits and vegetables used in a fruit sorting field of oranges and the like, instead of the conventional mechanical sorting, the bulky fruits and vegetables are photographed with a color CCD camera, and this imaging is engineered. Image processing measures the degree of coloring, scratches, shape, etc., and discriminates the grade / grade. In this case, up to now, only one scene can be shot by one camera. In addition, in the case of massive fruits and vegetables, the result often depends on the lighting device used at the time of photographing. That is, there are various kinds of luster on the surface of lumps of fruits and vegetables such as citrus fruits, and strong reflection (halation) is partially generated when these are irradiated with direct illumination. The current image processing sorting method uses an accurate determination of the location caused by this reflection.
It was impossible. Therefore, at present, an optical deflection filter is mounted on the light source and the lens of the camera to remove reflected light while performing direct illumination, and a large number of oversized light sources are arranged so as to obtain uniform illuminance (for example, actual See the back of Kaihei 4-51610).

なる等の欠陥を有する。However, in the case of spherical objects such as massive fruits and vegetables, it is not possible to capture the entire surrounding area by photographing only one surface (for example, a flat surface or a side surface). In order to take pictures of many surfaces, a plurality of cameras must be provided to complicate the device, and the degree of coloring, scratches, shapes, etc. of the entire block surface could not be easily and reliably detected. In addition, in a mode in which a filter is attached in order to prevent strong reflection from being given to massive fruits and vegetables upon photographing with a camera, an excessively large light source (a large number of light bulbs) is required because the amount of light is naturally reduced. Therefore, if the number of light sources is increased, power consumption for illumination is large, a large number of light bulbs are required, the frequency of bulb replacement is high, and maintenance is troublesome.

A camera is provided, and reflectors such as mirrors are arranged at four positions on the conveyor, which is the photographing range (field of view), so that the top and side surfaces (four side surfaces) of the bulk fruit and vegetables can be photographed simultaneously so that multiple surfaces can be photographed simultaneously. In addition, since the lighting for the block-shaped fruits and vegetables is used as indirect lighting means for reflecting the light from the reflecting wall surface of the housing-type reflective cover, the lighting for the block-shaped fruits and vegetables on the conveyor is substantially uniformly reflected light from various angles having no specific direction. Indirect lighting, and no strong reflected light in a specific direction is produced on the mass of fruits and vegetables. Therefore, a single color CCD camera is used to photograph multiple surfaces of massive fruits and vegetables (based on the measurement position of massive fruits and vegetables, the front, rear, left and right sides and the top surface of the conveyor), and captures reliable images without insufficient light due to reflected light. To obtain a plurality of images. That is, the clustered fruits and vegetables are photographed from multiple sides, and a wide range of images can be obtained. Based on this, reliable image processing can be performed.

効果を有する。As described above, the indirectly illuminated multifaceted photographing apparatus used in the camera for sorting bulky fruits and vegetables according to the present invention is an indirectly illuminated multi-sided photographing apparatus in which the main body of the apparatus is of a housing type having a reflecting wall and the illuminating light source emits reflected light. Lighting and a single color CCD camera, and a plurality of reflectors for multi-sided photography provided on both sides of the conveyor, which does not have a field of view, extend from the plane to the side of the bulk fruits and vegetables brought in by the conveyor. You can shoot a wide area (almost all). That is, so-called multi-surface simultaneous photographing can be performed, and image processing is performed using the multi-surface imaging, so that a wide range of measurement can be performed on a bulky fruit and vegetable. In addition, in this case, the lighting means is indirect lighting made by reflection of the reflecting wall surface of the inner wall of the housing which does not directly irradiate the clumps of fruits and vegetables. Accurate measurement can be performed without light. In addition, the illumination effect is high, the power consumption is smaller than the conventional direct illumination type using a deflection filter, and the light amount of the light source is less, so the bulbs that are consumables are small and the number is small. Frequency and running costs are reduced. Therefore, 1
Even when a color CCD camera is used, the accuracy of sorting and inspection can be significantly improved as compared with the conventional method.
