Claim 1:
2. The bidirectional compensation method for projection thermal defocusing as claimed in claim 1, S11 comprises:
S111: continuously acquiring two projected picture images; and
S112: determining whether a similarity value between the two projected picture images satisfies the preset similarity value requirement, in a case that the similarity value between the two projected picture images satisfies the preset similarity value requirement, proceeding to S12: driving a motor to rotate in a first direction by a preset number of steps, and then acquiring a projected picture image again and in a case that the similarity value between the two projected picture images does not satisfy the preset similarity value requirement, returning to S111: continuously acquiring two projected picture images.
