Surrounding information collection system and surrounding information acquisition apparatus

1. A surrounding information collection system comprising:

one or more processors configured to:

determine whether a number of stored sets of stored surrounding information is less than a predetermined number;

request a vehicle to transmit surrounding information;

wherein when the number of stored sets of stored surrounding information is determined to be less than the predetermined number, the vehicle requested to transmit the surrounding information is a vehicle that acquires additional surrounding information, the acquired additional surrounding information having an accuracy greater than a threshold calculated based on accuracy of the stored sets of surrounding information;

calculate the threshold using serviceability acquired from reducing, according to an elapsed time from when the additional surrounding information has been acquired by the vehicle, serviceability of the acquired surrounding information determined depending on the accuracy of the stored surrounding information; and

store the surrounding information transmitted from the vehicle in response to the requesting, wherein a score of a user of the vehicle that transmits the surrounding information in response to the request is increased so that an incentive according to the score is given to the user.

2. The surrounding information collection system according to claim 1 , wherein

the one or more processors are further configured to

receive accuracy of acquired additional surrounding information that the vehicle acquires, and

determine whether the received accuracy is greater than the threshold,

the vehicle acquiring the additional surrounding information being one for which accuracy is determined to be greater than the threshold.
