Calibrate floorplan projection

Generate the homography to project detections onto a floorplan.

POST/api/camera/calibrateFloorplanProjection

Authorizations

x-auth-apikeystringheaderrequired

Your Rhombus API key. Must be accompanied by the x-auth-scheme header set to api-token (or partner-api-token for partner endpoints).

Authorizationstringheader

Instead of an API key, an OAuth access token: Bearer <token>, with the write scope.

OAuth explains tokens and scopes.

Headers

x-auth-schemeenum<string>headerdefault: api-token

Authentication scheme identifier. Use api-token or partner-api-token with the x-auth-apikey header, api or partner-api with x-auth-apikey plus a client certificate, api-oauth-token or partner-api-oauth-token with x-auth-access-token, and federated-token with x-auth-ft. A request with Authorization: Bearer <token> and no x-auth-scheme is treated as OAuth, and federated-token may also be sent as the x-auth-scheme and x-auth-ft query parameters.

Available options: api-token, api, api-oauth-token, federated-token, partner-api-token, partner-api, partner-api-oauth-token

x-auth-orgstring<RUUID>header

Client organization UUID (22-character RUUID), for partner credentials only. With it the call runs in that client organization with the partner support authority's role. Without it a partner credential runs as the partner organization, which outside the partner endpoints is deprecated (responses carry Deprecation and Sunset: Tue, 05 Jan 2027 00:00:00 GMT). A malformed value returns 400 INVALID_AUTH_ORG; a client organization the partner cannot access returns 403 PARTNER_CLIENT_ACCESS_DENIED.

Length: 22 to 22
