Abstract
Techniques for calibrating a device having a stereoscopic camera are disclosed. According to an embodiment, the device calibrates the stereoscopic camera using a target provided by a mobile device. One or more zones each defining an area in a field of view of the calibrated stereoscopic camera are generated. The one or more zones are refined based on input provided by the mobile device.
Claims15
A computer-implemented method for calibrating a device having a stereoscopic camera, the method comprising:
- calibrating the stereoscopic camera using a target displayed on a mobile device, the calibrating comprising:
- detecting, via the stereoscopic camera, the target;
- generating one or more configuration parameters based on a position of the target relative to the stereoscopic camera;
- and
- calibrating the stereoscopic camera according to the configuration parameters;
- generating one or more counting zones each defining an area in a field of view of the calibrated stereoscopic camera;
- and
- refining at least one defined area of a counting zone of the one or more counting zones based on input provided by the mobile device, the refining comprising:
- receiving input indicative of one or more refinements to at least one defined area of a counting zone of the one or more counting zones from the mobile device;
- and
- updating definitions associated with the counting zone of the one or more counting zones based on the refinements.
A non-transitory computer-readable storage medium storing instructions, which, when executed, performs an operation for calibrating a device having a stereoscopic camera, the operation comprising:
- calibrating the stereoscopic camera using a target displayed on a mobile device, the calibrating comprising:
- detecting, via the stereoscopic camera, the target;
- generating one or more configuration parameters based on a position of the target relative to the stereoscopic camera;
- and
- calibrating the stereoscopic camera according to the configuration parameters;
- generating one or more counting zones each defining an area in a field of view of the calibrated stereoscopic camera;
- and
- refining at least one defined area of a counting zone of the one or more counting zones based on input provided by the mobile device, the refining comprising:
- receiving input indicative of one or more refinements to at least one defined area of a counting zone of the one or more counting zones from the mobile device;
- and
- updating definitions associated with the counting zone of the one or more counting zones based on the refinements.
A system, comprising:
- one or more processors;
- and
- a memory storing program code, which, when executed by the one or more processors, performs an operation for calibrating a device having a stereoscopic camera, the operation comprising:
- calibrating the stereoscopic camera using a target displayed on a mobile device, the calibrating comprising:
- detecting, via the stereoscopic camera, the target;
- generating one or more configuration parameters based on a position of the target relative to the stereoscopic camera;
- and
- calibrating the stereoscopic camera according to the configuration parameters;
- generating one or more counting zones each defining an area in a field of view of the calibrated stereoscopic camera, and
- refining at least one defined area of a counting zone of the one or more counting zones based on input provided by the mobile device, the refining comprising:
- receiving input indicative of one or more refinements to at least one defined area of a counting zone of the one or more counting zones from the mobile device;
- and
- updating definitions associated with the counting zone of the one or more counting zones based on the refinements.
