sim.checkVisionSensor

Checks whether the vision sensor detects the indicated entity. Detection is silent (no visual feedback) compared to sim.handleVisionSensor. The vision callback functions will be called on the acquired image. Also, the visibility state of the entity is overridden if the entity is an object

Synopsis

int result, list auxPacket1, list auxPacket2, etc. = sim.checkVisionSensor(int sensorHandle
                                                                           int entityHandle)

int result, float[] auxPacket1, float[] auxPacket2, etc. = sim.checkVisionSensor(int sensorHandle
                                                                                 int entityHandle)

Arguments

sensorHandle: handle of the vision sensor object
entityHandle: handle of entity to detect (object or collection), or sim.handle_all to detect all detectable objects

Return values

result: 0 (no detection) or 1 (detection)
auxPacket1: packet of 15 auxiliary values: the minimum of intensity, red, green, blue, depth value, the maximum of intensity, red, green, blue, depth value, and the average of intensity, red, green, blue, depth value
auxPacket2: additional auxiliary value packet (e.g. from an image processing component)
auxPacket3: etc. (the function returns as many tables as there are auxiliary value packets)
