The invention relates to a method and system for dynamically adjusting exhibition booth camera parameters according to object characteristics. The method includes a first step of creating a database of relation between object characteristics and scene modes, a second step of obtaining frames of objects on a table top, a third step of analyzing frames to obtain initialization parameters of a camera, and a fourth step of adjusting the working parameters of the camera according to the obtained initialization parameters. The types of the objects on the table top can be analyzed according to the real-time frames obtained from the table top, and corresponding scene mode is selected according to the types of the objects. The initialization parameters of the camera are adjusted, and scene mode required by the objects on the table top can be automatically provided to a user, and manual setting or changing scene mode by the user is not needed.
