Inspection assistance system, inspection assistance method, and program

An inspection assistance method comprising:

• a step of irradiating a transparent or translucent injection molding product with light from a lower side;
• a step of irradiating the injection molding product with light from an upper side;
• a step of performing first imaging for imaging the injection molding product in a state where the injection molding product is irradiated with the light from the lower side and second imaging for imaging the injection molding product in a state where the injection molding product is irradiated with the light from the upper side, by using a polarization camera;
• a step of acquiring a first captured image obtained by the first imaging and a second captured image obtained by the second imaging;
• and
• a step of analyzing at least one of the first captured image and the second captured image to present to a user presence or absence of a defect in the injection molding product.

A non-transitory computer readable medium storing a program, the program when executed by a computer, causing the computer to:

• irradiate a transparent or translucent injection molding product with light from a lower side;
• irradiate the injection molding product with light from an upper side;
• perform first imaging for imaging the injection molding product in a state where the injection molding product is irradiated with the light from the lower side and second imaging for imaging the injection molding product in a state where the injection molding product is irradiated with the light from the upper side, by using a polarization camera;
• acquire a first captured image obtained by the first imaging and a second captured image obtained by the second imaging;
• and
• analyze at least one of the first captured image and the second captured image to present to a user presence or absence of a defect in the injection molding product.
