Automatic adjusting of video analytics rules for camera movement

A system comprising:

• one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• maintaining, at a server, a first rule that specifies coordinate points of a first end of a first line and coordinate points of a second end of the first line in a first set of images from a camera,
• wherein the first line is monitored for object crossings in accordance with the first rule;
• providing, by the server to the camera, the first rule to be maintained at the camera;
• determining, by the server, an amount and direction of movement of the camera after the first rule was provided to the camera;
• in response to determining the amount and the direction of movement of the camera after the first rule was provided to the camera, determining, by the server and using the amount and direction of movement of the camera and the first end and the second end of the line, a first transformation for the coordinate points of the first end of the first line and a second transformation for the coordinate points of the second end of the first line, wherein the first transformation for the coordinate points of the first end of the first line match the amount and direction of movement of the camera;
• determining, by the server, coordinate points of a first end of a second line and coordinate points of a second end of the second line in a second set of images captured after the camera moved, the determining comprising:
• determining the coordinate points of the first end of the second line by transforming coordinate points of the first end of the first line by the first transformation, and
• determining the coordinate points of the second end of the second line by transforming coordinate points of the second end of the first line by the second transformation;
• transmitting, by the server to the camera, (i) the coordinate points of the first end of the second line and the coordinate points of the second end of the second line and (ii) a second rule to monitor the second line for object crossings;
• and
• triggering, by the server, at least one processor of the camera to monitor the second line maintained at the camera for object crossings in accordance with the second rule maintained at the camera instead of the first rule.

A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

• maintaining, at a server, a first rule that specifies coordinate points of a first end of a first line and coordinate points of a second end of the first line in a first set of images from a camera,
• wherein the first line is monitored for object crossings in accordance with the first rule;
• providing, by the server to the camera, the first rule to be maintained at the camera;
• determining, by the server, an amount and direction of movement of the camera after the first rule was provided to the camera;
• in response to determining the amount and the direction of movement of the camera after the first rule was provided to the camera, determining, by the server and using the amount and direction of movement of the camera and the first end and the second end of the line, a first transformation for the coordinate points of the first end of the first line and a second transformation for the coordinate points of the second end of the first line, wherein the first transformation for the coordinate points of the first end of the first line match the amount and direction of movement of the camera;
• determining, by the server, coordinate points of a first end of a second line and coordinate points of a second end of the second line in a second set of images captured after the camera moved, the determining comprising:
• determining the coordinate points of the first end of the second line by transforming coordinate points of the first end of the first line by the first transformation, and
• determining the coordinate points of the second end of the second line by transforming coordinate points of the second end of the first line by the second transformation;
• transmitting, by the server to the camera, (i) the coordinate points of the first end of the second line and the coordinate points of the second end of the second line and (ii) a second rule to monitor the second line for object crossings;
• and
• triggering, by the server, at least one processor of the camera to monitor the second line maintained at the camera for object crossings in accordance with the second rule maintained at the camera instead of the first rule.
