Lamp bead position detection method, computer apparatus and program product

A lamp bead position detection method, comprising:

• sorting lamp beads according to the total number of the lamp beads in a lamp chain, and determining a sequence number of each lamp bead;
• applying recursive segmentation to the lamp chain according to the sequence number to obtain sequence number ranges of lamp beads correspondingly covered by multiple segments, and after each segmentation, controlling each segment obtained from the current segmentation to present a different apparent color through the lamp beads from other segments;
• identifying spatial positions and apparent colors of light-emitting lamp beads in a captured image of the lamp chain as correspondingly acquired in each segmentation, and determining sequence number ranges to which the light-emitting lamp beads in the image belong according to the segment to which the apparent colors belong;
• and
• determining a mapping relationship between a spatial position and the sequence number of each lamp bead according to a spatial positional relationship between adjacent lamp beads in the captured image and a sequence number relationship within the sequence number ranges to which they belong.
