A camera tracking method, applied in a director system in a conference site, wherein the director system comprises a first camera, a first director camera and a second director camera, wherein the first camera is a binocular camera, the method comprising: determining, by a director device, historical speech information in a preset time period based on first video information collected by the first camera in the preset time period and first audio information collected by a plurality of microphones, MICs, in the preset time period, wherein the first camera is configured to collect a local video; determining, by the director device, a current speaker based on second video information collected by the first camera at a current moment and second audio information collected by the plurality of MICs at the current moment; determining, by the director device, a quantity of effective speech times, being the count of effective speeches, of each speaker based on a priority of each speaker in the preset time period and speech duration of each speaker in each speech in the preset time period, wherein each speaker has a priority and the priority of each speaker is preset by an administrator in the director device or the priority of each speaker is determined based on a seat of the speaker in the conference site, wherein each seat in the conference site has a preset priority, and wherein a speech is determined as an effective speech when speech duration of a speaker in a speech is greater than an effective speech duration threshold corresponding to the priority of the speaker; determining, by the director device, a speaker whose quantity of effective speech times is greater than or equal to 1 as an effective speaker; counting, by the director device, a quantity of effective speakers to determine the quantity of effective speakers; determining, by the director device, a speech mode in the preset time period based on the quantity of effective speakers in the preset time period; and adjusting, by the director device, when the current speaker is different from a speaker shot by the first director camera at the current moment, a shooting angle or a focal length of at least one of the first director camera and the second director camera based on the historical speech information and the speech mode in the preset time period. determining, by a director device, historical speech information in a preset time period based on first video information collected by the first camera in the preset time period and first audio information collected by a plurality of microphones, MICs, in the preset time period, wherein the first camera is configured to collect a local video; determining, by the director device, a current speaker based on second video information collected by the first camera at a current moment and second audio information collected by the plurality of MICs at the current moment; determining, by the director device, a quantity of effective speech times, being the count of effective speeches, of each speaker based on a priority of each speaker in the preset time period and speech duration of each speaker in each speech in the preset time period, wherein each speaker has a priority and the priority of each speaker is preset by an administrator in the director device or the priority of each speaker is determined based on a seat of the speaker in the conference site, wherein each seat in the conference site has a preset priority, and wherein a speech is determined as an effective speech when speech duration of a speaker in a speech is greater than an effective speech duration threshold corresponding to the priority of the speaker; determining, by the director device, a speaker whose quantity of effective speech times is greater than or equal to 1 as an effective speaker; counting, by the director device, a quantity of effective speakers to determine the quantity of effective speakers; determining, by the director device, a speech mode in the preset time period based on the quantity of effective speakers in the preset time period; and adjusting, by the director device, when the current speaker is different from a speaker shot by the first director camera at the current moment, a shooting angle or a focal length of at least one of the first director camera and the second director camera based on the historical speech information and the speech mode in the preset time period.
